XBI unusual options flow

Latest scored XBI prints

How the score works

Every print gets a 0 to 100 score from premium size, aggressiveness of the fill, volume versus open interest, time to expiry and how far the strike sits from the stock. A XBI sweep at the ask with big premium and short dating scores high. The full method is in the unusual options flow guide.

What unusual XBI options flow can tell you

Not every XBI options trade matters. What moves the needle is size and intent: a large premium order swept across the ask, a block printed far from the current price, or a burst of short-dated contracts ahead of a catalyst. When call premium dominates the XBI tape, traders are paying up for upside; when puts lead, they are paying for protection or positioning for a fall. The scored view on this page separates those standout orders from routine two-way flow, so you are reading intent rather than raw volume.

How to read the XBI tape

Start with the call-versus-put premium split at the top of the page: it is the fastest read on which way the day's money is leaning in SPDR Biotech ETF. Then look at the individual prints. A high score means real premium, an aggressive fill, and short dating relative to how far the strike sits from the stock, the combination that tends to lead a move rather than follow it. One large XBI sweep says more than a hundred small, evenly split orders. Because the same method runs on every name, a XBI score is directly comparable to any other ticker on the board.

Why traders watch XBI

SPDR Biotech ETF is the biotech sector chain, a favorite for catalyst season. That is exactly why its options chain draws attention: liquid, active names give the clearest read on where conviction is building, and their flow often moves before the headlines catch up. RadarPulse keeps the most unusual XBI prints from the latest session next to Congressional trades and 13F filings on the same tickers, so you can see when more than one kind of smart money lines up on XBI.

XBI and the index and sector etfs

XBI sits in the index and sector etfs group, the index and sector ETFs where macro hedges and broad conviction land. Traders often watch the whole cluster together, since a strong, one-sided bid in one name can front-run a rotation the rest follow. When unusual XBI flow shows up, it is worth checking whether the same conviction is printing across peers like SPY, QQQ, IWM. RadarPulse scores every one of them on the same 0 to 100 scale, so the read is apples to apples across the index and sector etfs.
