What the institutional money is doing on INSM right now — dark pool, options positioning, and where the news and the money disagree. Free.
News frames this as a competitive horse race, but options traders have built almost no new positions and are holding balanced hedges—no conviction on either direction.
The news is promotional, but options traders have not positioned ahead of the event—no new bets placed, suggesting low near-term catalyst expectations.
The news hints at smart-money accumulation in healthcare, but Insmed's own options show no new positioning and below-normal off-exchange activity—no evidence of institutional buying here.
News confirms passive ownership, but options traders show no new directional conviction and are trading well below their normal off-exchange volume—passive holding, not active accumulation.
This is a concrete positive catalyst—first-in-class approval—yet options traders have not opened new upside positions and off-exchange volume remains 35% below normal, suggesting the market has already priced it in or lacks conviction.
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).
