How options flow changes during earnings season

What earnings season does to implied volatility

The single most pervasive effect of earnings season on the options tape is elevated implied volatility. Before a company reports, the options market prices in uncertainty about what the results will be. That uncertainty appears in IV: options in the name become more expensive relative to historical realised volatility, because buyers are paying for the possibility of a large post-announcement move in either direction.

This IV elevation does not affect one company in isolation during earnings season, it affects dozens of major names simultaneously across four to six weeks. The result is a market-wide IV environment that is structurally higher than non-earnings periods, which has several downstream effects on how the flow reads.

First, options are more expensive to buy, which means the absolute premium on any given print is higher even at the same notional exposure. A call sweep that would cost $300K in a normal week might cost $500K on the same number of contracts in a high-IV environment, because each contract carries more premium. This makes premium size a less reliable proxy for position size during earnings season.

Second, the Vol/OI ratio becomes more important. Since elevated IV makes options more expensive across the board, a high Vol/OI ratio, which measures contracts traded relative to prior open interest, not dollar premium, becomes the cleaner signal of genuine new positioning versus hedging.

The hedging surge: why earnings season generates so much noise

Every major company reporting results means that every institutional fund holding that stock faces binary earnings risk. A fund long 500,000 shares of a large-cap company does not want to absorb the potential 10–20% single-day drawdown if the company misses estimates badly. The standard institutional response is to buy protective puts before the announcement.

During earnings season, this is not one fund hedging one position. It is dozens of large funds simultaneously hedging dozens of large positions across the entire earnings calendar. The resulting put flow is real, large-premium, and often sweep-executed, exactly the characteristics of a directional bearish signal. But structurally it is portfolio insurance, not directional conviction.

The practical implication: any scanner running without an earnings-proximity filter during earnings season is flooded with hedging puts that make names look under institutional bearish attack. The actual signal, funds that are building new directional positions unrelated to their existing equity holdings, is buried beneath the hedging noise.

The four adjustments to make during earnings season

IV crush: the most important post-earnings mechanics

IV crush is the sharp drop in implied volatility that occurs immediately after a binary event resolves. Before an earnings announcement, IV is elevated because the market is pricing in the possibility of a large move in either direction. After the announcement, that uncertainty is gone, the results are known, and the ongoing residual risk of a surprise is much lower. IV contracts sharply, sometimes by 30–50% in a single session.

For options holders, IV crush compresses the market value of their contracts even if the stock moves in their favour. A trader who bought calls expecting a 5% upside and got exactly that can still lose money if the IV crush reduces the option's vega value more than the directional delta gain adds. This mechanics, right on direction, wrong on the trade, is one of the most common expensive mistakes in options trading around earnings.

For flow readers, IV crush creates a post-earnings environment where options are temporarily cheaper in the reporting name. Flow that appears in a name shortly after the IV crush can represent institutions initiating or adding to positions at more attractive premiums than they could have gotten before the announcement. A post-earnings call sweep in a name that beat expectations can be a high-conviction long signal: the buyer is adding exposure after the binary risk is gone, at compressed premiums, with a view on continued upside rather than just the pop.

What strong earnings-season flow looks like

The highest-conviction flow during earnings season tends to come from two categories:

Names well outside the earnings window. A mid-cap company with its earnings report eight weeks away showing a $2M call sweep with 12× Vol/OI in a 45-DTE OTM strike is an unusually clean signal precisely because no earnings context explains it. There is no pre-announcement hedging rationale, no IV elevation from a pending binary event. The institutional buyer is expressing a pure directional view with a defined six-week thesis. These prints tend to be more actionable than the same print in a name reporting in three days.

Post-earnings continuation flow. A company that reported strong results and saw the stock gap up on strong volume will subsequently show post-earnings follow-through in the options market, funds that missed the initial reaction adding exposure after the fact, or existing longs adding to positions with the binary risk resolved. Post-earnings call sweeps at crushed IV levels, in names with strong results, represent a distinct institutional positioning pattern with its own signal profile.

The interplay with the VIX during earnings season

The VIX, the market's real-time measure of 30-day implied volatility on the S&P 500, typically remains elevated during peak earnings season as the aggregated uncertainty from major company reports creates market-level vol. This VIX elevation is a background signal that the entire options market is in a higher-premium state. When the VIX is elevated above 20, option premiums are expensive across the board; when it falls below 15, options are cheap and unusual premium-sized prints carry different weight.

For practical flow reading: during earnings season with elevated VIX, the premium threshold for "significant" may need to be raised proportionally. A $300K print in a low-VIX environment is notable; the same absolute dollar amount in a high-VIX environment may reflect fewer contracts and less conviction than the dollar figure implies. Vol/OI ratio, which is VIX-neutral, is a more consistent signal across different volatility regimes.

Seasonal calendar: when earnings season peaks

Earnings season runs on a predictable quarterly calendar. For context:

• Q4 earnings (January–February): Reporting prior-year full results. Large-cap tech, banks, and consumer names report in the first two weeks of January through mid-February.
• Q1 earnings (April–May): Typically the most concentrated period, the bulk of S&P 500 companies report in a three-to-four week window in April and early May.
• Q2 earnings (July–August): Mid-year results. Overlaps with summer market seasonality.
• Q3 earnings (October–November): Third-quarter results, often accompanied by management guidance revisions that affect the following year's outlook.

Outside these four windows, roughly eight weeks per quarter, the options tape is in a lower-noise state where unusual flow in a name has fewer competing explanations. The six weeks between earnings seasons are typically the cleanest environment for directional flow reading.

The pre-earnings flow window: days 1–10 before the announcement

Pre-earnings options flow does not arrive uniformly across the ten trading days before a company reports. It arrives in distinct waves, and each wave carries a different mix of directional conviction versus risk management. Understanding which wave you are reading is the difference between acting on a signal and acting on noise dressed up as a signal.

Days 10–8 before earnings: the high-information window. Institutions that have done genuine primary research, channel checks with suppliers and distributors, conversations with industry contacts, detailed proprietary financial models, tend to position early. Early positioning serves two purposes: it captures cheaper options before IV fully reflects the event premium, and it avoids the crowd of late-arriving flow that compresses fills in the final days before the announcement. A sweep arriving nine or ten days before earnings represents a buyer who had both the conviction and the operational capacity to act before the rest of the market bid up the IV. These are the highest-information pre-earnings signals on the tape.

Days 7–5: IV acceleration begins. As the announcement date approaches, market makers widen implied volatility to compensate for the binary risk they are taking on as options sellers. The options market "prices in" the earnings event more aggressively during this window. Flow in days 7–5 may still be directional, latecomers expressing a view, but it increasingly overlaps with another source: market makers themselves delta-hedging their own inventory. A market maker who is net short calls adjusts their hedge by buying the underlying stock or offsetting options as IV moves. This rebalancing creates prints that look like institutional flow but are mechanically generated. Separating directional flow from market-maker rebalancing in the 7–5 window requires looking carefully at routing (single exchanges often indicate retail or desk hedging; multi-exchange sweeps suggest directional intent) and whether the trade is adding new open interest or trading against existing positions.

Days 4–2: the noise floor peaks. Risk managers at funds with existing equity positions in the name are required, by mandate, by VAR constraints, or simply by prudence, to buy protective puts before a binary event of this magnitude. They are not making a directional bet. They are paying the cost of insurance on an existing position. During days 4–2, this institutional risk-management flow floods the tape with large-premium put prints. Straddle and strangle buyers, volatility traders who profit from large moves in either direction without caring about direction, also peak in this window. The result: raw put volume is highest, raw premium on the tape is highest, but the directional content per dollar of premium is lowest. A put sweep on day three before earnings should be treated with significant skepticism unless multiple other factors, Vol/OI well above 10×, unusual strike selection far OTM, a name with no obvious existing institutional long position to hedge, argue against the hedging interpretation.

Day 1 (earnings eve): signal value is lowest. The final 24 hours before the announcement is the most expensive options environment of the quarter for that name. IV is at its peak. Any sweep on earnings eve is paying the maximum premium for the minimum remaining time. These prints are almost entirely event hedges (institutional longs protecting against overnight gap risk), last-minute position covers (traders closing positions before the event rather than holding through it), or highly speculative 0DTE or 1DTE plays that expire the next session. The speculative 0DTE plays are directional in intent but are typically retail-sized and signal nothing about institutional conviction. Treat all earnings-eve flow as high noise, low signal.

The inverse rule: proximity to earnings is inversely related to directional content. The key insight that synthesises the above is a sliding confidence discount on pre-earnings flow based on how close it arrives to the announcement date. A sweep arriving 10 days before earnings carries the highest probability of being directional institutional conviction. A sweep arriving 2 days before carries the lowest. This is not absolute, there are exceptions, but as a prior applied to the entire pre-earnings universe, it holds well. When evaluating any pre-earnings print, the first question should be: how many trading days away is the announcement date?

Post-earnings flow: the three patterns that matter

Once a company reports, the options tape in that name resets. IV crush compresses premium. Hedging positions unwind. What remains is new positioning, and new positioning after an earnings announcement has high information content because the buyer already knows the result. There is no earnings-outcome uncertainty for post-report flow. It is pure directional or recovery thesis, expressed in a crushed-IV environment.

Three distinct post-earnings flow patterns appear repeatedly on the tape, each with its own read and action implication.

Pattern 1, IV crush plus call sweep: the continuation buy. A company reports a strong beat. The stock gaps up 8% at the open. IV crushes 35–45% on that same session as the uncertainty that inflated pre-earnings options is resolved. In the hours after the announcement, same session or next session, a large call sweep appears in the next expiry (15–30 DTE), routed across multiple exchanges at the ask. This is the post-earnings pattern with the clearest signal. The institution paying up for these calls already knows the results. They have absorbed the gap. They are not positioning for the earnings pop, they missed it or chose not to. They are initiating a new multi-week thesis on continued momentum: the beat is real, the guidance is strong, and the stock has further upside over the next month. The use of a near-term expiry (15–30 DTE) confirms they are not expressing a long-term investment view; this is a momentum continuation trade. The crushed IV makes the options cheaper than they were pre-report, which is an added incentive to position now rather than before. Post-earnings continuation sweeps in a name that beat estimates are among the cleanest signals of the earnings season cycle.

Pattern 2, Post-earnings put sweep against a small gap: the partial exit. A company beats estimates but the stock barely moves, up 2% on a pre-earnings implied move of 6%. The stock's post-earnings trajectory is technically positive, but the move disappointed relative to what the options market was pricing in as likely. Institutions that held the stock into earnings as a directional bet (expecting a larger move) are now in a complicated position: the thesis worked directionally, but the magnitude underdelivered. In this scenario, put sweeps may appear, not as an expression of bearishness, but as partial position hedging. An institution that was long both stock and calls into earnings may sell part of the upside and buy near-dated puts to protect the remaining position. The resulting print looks like a bearish signal on a scanner but is better read as a position management trade. The distinguishing factors: stock is up (not down), put DTE is short (hedging against further disappointment), and Vol/OI may be moderate rather than extreme. This pattern is ambiguous, it is worth noting, but it does not have the directional clarity of Pattern 1 or Pattern 3.

Pattern 3, Post-miss reversal call sweep: the dip buy. A company misses estimates. The stock falls 12–15% in a session. IV was already elevated pre-earnings; post-miss, the stock drops sharply and IV partially recovers (because downside uncertainty increases). Two to three sessions after the initial selloff, the stock stabilises near a technical support level. Then a large call sweep appears: 30–60 DTE, ask-side, Vol/OI above 6×, at a strike 10–15% above current price. This is the smart-money dip buy pattern, and it is one of the more reliable post-earnings setups on the tape. The institution is making a specific argument: the market overreacted to the miss. The long-term thesis is intact. The stock at this price represents value. The use of 30–60 DTE (rather than 7–14 DTE) is the key tell, it signals a multi-week recovery thesis, not a short-term bounce trade. The institution is not playing for a single session; they are expressing a view that the stock will recover meaningfully over the next month or two. The OTM strike selection (10–15% above current price) amplifies the recovery thesis further, they need a substantial move to profit, but they're willing to take that risk because they believe the selloff was excessive. When this pattern appears near technical support with high Vol/OI and a 45+ DTE expiry, it warrants close attention.

Finding the clean flow during earnings season: the non-reporting universe

The most common mistake during earnings season is treating the entire options tape as uniformly contaminated by earnings noise. It is not. At any point during the six-to-eight-week earnings window, only a fraction of the investable universe is in active pre-announcement hedging mode. The rest of the market, names that have already reported or are far from their next reporting date, is generating flow in an environment largely uncontaminated by earnings-specific distortions. This is the clean universe, and during earnings season it is the highest-quality flow environment available.

The window structure of earnings season. The S&P 500 does not report simultaneously. The calendar is staggered across six to eight weeks, with different sectors on different schedules. Banks report in the first two weeks of January; technology mega-caps follow in late January and early February; consumer names stagger through February. At any point during this period, 60–70% of names have either already reported (post-IV crush, post-hedging unwind) or have not yet entered their pre-announcement hedging window (earnings more than 10 trading days away). These names represent the majority of the universe despite being in an earnings-season calendar context.

How to identify the clean universe. The filter is straightforward: a name is in the clean window if its next earnings date is more than 10 trading days away AND its prior quarterly results have been public for at least 5 trading days (enough time for post-earnings hedging unwinds to clear). Names that satisfy both conditions can be evaluated with standard flow analysis methodology, the same score thresholds, Vol/OI criteria, and DTE windows that apply in non-earnings periods. Names that fail either condition get the elevated-noise treatment: higher score threshold, closer scrutiny of hedging vs directional routing, and the sliding pre-earnings confidence discount from the section above.

Why clean-window names are especially interesting during earnings season. During earnings season, the attention and capital allocation capacity of institutional trading desks is heavily consumed by managing their earnings-exposed positions. A fund with concentrated positions in ten reporting names spends the bulk of its risk management bandwidth on those ten names during the earnings window. Against that backdrop, a fund that chooses to initiate a significant new options position in a name entirely unrelated to earnings, a clean-window name, is making a deliberate choice to deploy capital in a non-earnings context despite the surrounding noise and competing demands. The conviction implied by that deliberate attention allocation is itself a secondary signal. A $3M call sweep in a clean-window name during peak earnings season carries a different weight than the same print outside earnings season, because the institution is competing for bandwidth with a dozen active earnings decisions to make that trade.

The cross-sector rotation thesis. A particularly powerful clean-window pattern emerges when a non-reporting mid-cap in a sector shows large call sweeps while that sector's leading names are actively reporting strong results. Consider a scenario where large-cap cloud software companies are reporting and beating estimates across the board. Their earnings calls are full of positive commentary on enterprise IT spending. Two days after the second major beat, a mid-cap infrastructure software company, which reports in eight weeks, sees a $2.5M call sweep with high Vol/OI at the ask. This is not a coincidence. Institutions are reading the sector's earnings commentary and rotating into names that will benefit from the same tailwinds but haven't yet had their results reflect it. The clean-window mid-cap is a sector rotation trade grounded in the leading names' earnings data. This is one of the most information-dense flow patterns available during earnings season: the buying institution is using real, freshly reported data from peer companies to make their positioning decision.

Practical workflow during earnings season. The cleanest operating procedure is to maintain a separate "clean window" watchlist that refreshes daily based on the reporting calendar. As the calendar updates, new names report, new names enter the pre-announcement window, the clean list shifts. Flow alerts in clean-window names get processed with standard methodology. Flow in pre-announcement names get the earnings-proximity discount. Flow in names within 48 hours of reporting gets discarded for directional purposes. This three-tier triage keeps the signal-to-noise ratio manageable throughout the six-to-eight-week period rather than treating the entire season as uniformly degraded.

Reading sector-wide earnings flow patterns

Single-name flow analysis during earnings season captures one dimension of the information available on the tape. The second dimension, which is often underutilised, is the inter-name flow pattern across a sector as the earnings calendar unfolds. Sectors do not report all at once; they report sequentially, with some names going first and others following days or weeks later. That sequence creates a structured information cascade that sophisticated institutions exploit, and the flow tape records it.

When sector leaders report: the extrapolation effect. Technology mega-caps report in a specific sequence each earnings season. The results of the first name set expectations for the entire group. When the leading name beats estimates and provides strong guidance on a key theme, AI infrastructure spending, cloud adoption rates, digital advertising recovery, institutions immediately begin repositioning in the names that haven't yet reported. The call flow in the second and third names to report begins to accumulate within 24–48 hours of the first name's results. By the time the third name reports, the institutional view on the sector's earnings trajectory has been substantially shaped by the first two reports, and that view is already written into the options tape of every subsequent reporter in the group. Reading the sector flow sequence, not just each name in isolation, reveals the institutional consensus view as it forms in real time.

The sector contagion effect. A significant beat from one leading name creates call flow propagation across the entire sector within hours. The pattern is consistent enough to qualify as a repeatable trading signal: watch for unusual call activity in sector peers within 24–48 hours of a leading name reporting strong results. The corollary holds as well, a significant miss creates put hedging propagation across the sector. The speed of this propagation has increased in recent years as algorithmic institutional desks process earnings transcripts and guidance commentary in real time and reposition simultaneously across the sector. The flow appears on the tape before the sell-side has even published its morning-after research notes on the leading reporter.

The "ahead of the reporting peers" pattern. In sectors with a staggered earnings calendar, the early reporters serve as leading indicators for the late reporters. When a mid-cap regional retailer reports first in the retail earnings cycle and shows strong same-store sales growth and upbeat consumer commentary, the options tape in the large-cap retailers who report two to three weeks later will reflect this almost immediately. Institutions extrapolate from the mid-cap's real consumer data to their large-cap positioning. Call sweeps in TGT, WMT, or COST following a strong mid-cap retail report, before the large-caps have reported, represent one of the most information-dense patterns on the earnings-season tape. The institution is not guessing; they are using reported data from an early reporter to predict the late reporter's results.

Banking season as the canonical example. The financial sector earnings calendar in January is the clearest available illustration of sequential sector flow analysis. JPMorgan, Wells Fargo, Citigroup, and Goldman Sachs typically report in the first two weeks of January, followed by regional banks days later. After the mega-bank reports are complete, the options tape in the regional bank ETF (KRE) and individual regional names (ZION, FHN, FITB) tells a clear story: if the sector's results are collectively strong, net interest margins holding, credit quality intact, loan growth positive, call flow propagates into the regionals before they report. If the mega-banks show credit stress or NIM compression, put flow appears in the regionals. The regional bank tape in mid-January is essentially a real-time institutional survey on whether the mega-bank results represent the sector or just the largest players. Knowing how to read that sequential flow gives you the institutional sector view before the regional earnings arrive.

How to track this systematically. The key tool is a sector reporting calendar that shows which names within each sector report early versus late. With that calendar in hand, you can build a monitoring workflow: when an early reporter releases results, immediately scan for unusual call or put flow in the late reporters in the same sector over the subsequent 48 hours. A spike in Vol/OI across multiple late reporters in the same sector following an early reporter's beat is the inter-name propagation pattern in action. Most flow platforms aggregate by ticker, not by sector sequence, the analyst's job is to apply the sector calendar context to what is otherwise a list of individual prints.

Case studies: earnings-season flow that worked and flow that didn't

Abstract frameworks are only as useful as the concrete scenarios that validate them. Three detailed scenarios below illustrate the concepts from earlier sections in practice, two where reading the flow correctly would have been profitable, and one where a common misread would have led to an incorrect directional conclusion.

Scenario 1, Early pre-earnings positioning that paid off. A large-cap enterprise software company is nine trading days from its quarterly earnings announcement. The stock has drifted sideways for three weeks and shows no unusual activity on standard scanners. On this day, a $3.1M call sweep appears: 21 DTE, 5% OTM strike, routed across three exchanges at the ask within a 14-minute window. Vol/OI is 9.4×, confirming that this is new positioning, not trading against existing open interest. Implied volatility is elevated but has not yet reflected the full earnings event premium, earnings are still more than a week away, so the market has not fully priced in the binary risk.

Applying the pre-earnings proximity framework: nine days out places this squarely in the high-information window (days 10–8). The routing (multi-exchange sweep) and timing (mid-session, not a burst of small orders) are consistent with institutional execution. The 21 DTE expiry means the option will expire roughly 12 days after the earnings announcement, enough time to participate in a post-earnings run if the results are strong, without exposing the buyer to the long slow theta decay of a 60-DTE position. Two days later, IV on the name rises a further 15% as the event premium builds. At expiration, the company reports a significant beat, the stock gaps up 11%, and the calls settle at approximately 4.1× the premium paid. The early buyer captured both the directional move and the IV expansion between day 9 and the announcement. The lesson: early pre-earnings sweeps with high Vol/OI, multi-exchange routing, and a DTE that spans just past the announcement date represent the earnings-season flow setup with the best risk/reward on the pre-report side.

Scenario 2, The earnings hedge misread. A well-known mega-cap consumer technology company is three trading days from its earnings announcement. A $14.8M put block appears on the tape: single exchange, mid-market fill, 7 DTE (expires two days after earnings). Every basic flow alert fires, this is the largest put print in the name in three months. Financial media picks up the alert. The stock falls 2.3% that session, partly attributed to the "bearish flow." After earnings, the company reports a strong beat across all metrics and the stock rallies 9% in the following session. The put block loses most of its value.

The flags that identified this as a hedge rather than a directional bet were present from the start: it was a block (printed as a single transaction on one exchange), not a sweep (aggressive market-order execution across multiple venues). The fill was mid-market, not at the ask, a buyer with directional conviction pays the ask to ensure execution; a hedger is indifferent to whether they get mid or slightly below mid because their goal is protection, not aggressive entry. The DTE of 7 meant the option expired two days after earnings, the minimum protective window, consistent with an overnight insurance purchase rather than a multi-week bearish thesis. And the date, day three before earnings, placed it squarely in the peak-noise window for risk-management puts. The $14.8M figure was large enough to attract attention, but size is not signal. A fund long $900M of the stock in its portfolio spends $14.8M on a short-dated put block as cheap insurance. The lesson: block routing, mid fill, and earnings proximity (days 4–2) together override any amount of premium. These structural characteristics mean hedging, not direction, almost every time.

Scenario 3, Post-earnings continuation call sweep in a beaten-down name. A mid-cap biotechnology company reports quarterly earnings that miss revenue estimates by 8% and reduce full-year guidance slightly. The market reacts sharply, the stock falls 14% in a single session. IV spikes during the sell-off (implied volatility on a name that just had a negative binary event often rises, not falls, because the uncertainty about the longer-term impact of the miss creates new vol premium). The stock settles near a technical support level established during the prior quarter's consolidation.

Three trading sessions after the initial drop, the stock is flat to slightly up, the immediate selling has exhausted itself. A $2.4M call sweep appears: 45 DTE, 12% OTM strike (meaning the stock needs to rally 12% from current levels to reach the money), ask-side execution across two exchanges, Vol/OI of 6.2×. This is Pattern 3 from the post-earnings framework, the post-miss recovery thesis.

The read on this print is informed by several converging signals. The 45 DTE immediately disqualifies it as a short-term bounce trade, a day trader or a speculator on a mean-reversion spike would use 7–14 DTE. The 45-day window is multi-week positioning. The 12% OTM strike communicates that the buyer believes the selloff was an overreaction: they need a significant recovery to profit, and they are comfortable initiating at that level. The ask-side execution signals urgency, they wanted to be positioned now, before a potential recovery begins. The Vol/OI of 6.2× confirms this is new open interest, not a roll or hedge on an existing position. IV at this point is partially elevated from the post-miss uncertainty, but lower than the pre-earnings peak, giving the buyer a reasonable entry on option premium. The lesson: post-earnings put flow (the initial sell-off) and post-earnings call flow (the recovery thesis) are structurally different animals. The put flow that accompanies a miss is often reactive and mechanical. The call flow that appears two to three sessions later in a stabilised, beaten-down name is deliberate and thesis-driven. It is the more actionable post-earnings signal of the two.

Frequently asked questions

How does earnings season affect options flow?

Earnings season creates elevated market-wide implied volatility, a surge in options volume, and widespread pre-earnings protective put buying that generates large-premium prints across the tape. These hedging prints can bury genuinely directional signals. The key adjustments: extend the earnings exclusion window to 10 trading days, raise the score threshold, prioritise names that have already reported (post-IV crush), and treat sector-wide flow patterns separately from single-stock reads.

Is options flow reliable during earnings season?

Options flow during earnings season is noisy but not useless. Filtering more strictly, score threshold 85+, earnings exclusion 10 days, keeps the cleanest signals visible. Names well outside their reporting window and names that have already reported are the best flow-reading environments during the period. The six weeks between earnings seasons are the cleanest environment for standard flow analysis.

What is IV crush in options flow?

IV crush is the sharp post-announcement drop in implied volatility. Before earnings, IV is elevated because options price in uncertainty about the result. After the announcement, that uncertainty collapses and IV drops sharply, compressing options prices regardless of which direction the stock moved. IV crush is why buying options into earnings can lose money even when you're right on direction. Post-earnings, crushed IV creates cheaper options, which can make post-result institutional positioning more attractive to buy.

How do I filter options flow during earnings season?

Four adjustments: extend the earnings exclusion window from 5 to 10 trading days; raise the score threshold to 85+; prioritise names that have already reported and where IV crush has occurred; and read sector-wide flow patterns as macro signals rather than individual conviction. Vol/OI ratio is more reliable than absolute premium during earnings season since VIX elevation makes the same premium buy fewer contracts.

What happens to options flow after earnings?

After a company reports, IV crush compresses remaining options premium sharply. Post-earnings flow reflects position adjustments, covering shorts, rolling options, or new directional positioning based on the results. Post-earnings call sweeps in a company that beat expectations can be high-conviction signals: the buyer is adding long exposure after the binary risk is resolved, at crushed IV levels, expressing confidence in continued upside rather than just the initial earnings reaction.
