What the institutional money is doing on BBIO right now — dark pool, options positioning, and where the news and the money disagree. Free.
Strong clinical data contrasts with defensive option positioning: puts outnumber calls 1.32-to-1, and no new bullish option positions opened despite the announcement.
Positive pipeline milestone arrives with put-heavy option hedging (1.32 put-call ratio) and no new upside positioning, indicating skepticism about near-term catalysts.
Accelerating sales growth clashes with defensive hedging: put-call ratio of 1.32 and no new bullish option opens suggest institutions are bracing for execution or cash-burn concerns.
Recent rally sits against put-heavy option positioning (1.32 ratio) and no fresh bullish bets, suggesting smart money is hedging upside rather than chasing it.
Bullish sales narrative meets defensive option structure: put-call ratio of 1.32 and no new upside positioning indicate institutions are pricing in execution and cash-burn risk despite revenue momentum.
A divergence is when the news narrative and the institutional money flow point in opposite directions — a bearish headline while large call premium is bought, or heavy dark-pool selling under a bullish story. It signals the crowd and the desks may disagree.
Dark-pool volume — The share of trading executed off-exchange, at wholesalers and dark pools. About half of all US share volume prints there on an ordinary day, so the level by itself says almost nothing. What carries information is the distance from this name’s own recent norm, and whether the off-exchange size ran above its usual.
Off-exchange short share — How much of that off-exchange volume was sold short. The median across all listed names is about 49%, because wholesalers filling retail buy orders sell short and cover later. A reading near half is plumbing, not a bearish vote — compare it to the same name’s own 20-day norm.
Max pain — The price where the most options expire worthless — positioning often gravitates toward it near expiry.
Call wall / Put floor — Strikes with the heaviest call/put open interest — they often act as short-term resistance and support.
Put/Call ratio — Below ~0.7 leans bullish (more calls); above ~1 leans defensive (more puts).
