ECL max pain for the Oct 16, 2026 expiry is $270, from the Fri Oct 2 options chain. The last price, $277.07, is 2.6% above it. Call wall $300 · put floor $270.
What the institutional money is doing on ECL right now — dark pool, options positioning, and where the news and the money disagree. Free.
The options market is priced for upside (three times more calls than puts in open positions), but no new money has entered recently, so this bullish lean reflects older conviction rather than fresh buying.
Options traders are positioned for upside (call-heavy), but the lack of fresh positioning and below-normal off-exchange volume suggest this view is not being actively reinforced by new institutional money.
Options positioning remains call-heavy, but no new contracts have opened recently, indicating the bullish lean is static rather than building.
Call-heavy options positioning aligns with the dividend-strength narrative, but the absence of new open interest means traders are not actively betting on acceleration.
Options traders favor calls over puts by a wide margin, and the stock is trading near the call-strike wall at $300, consistent with bullish positioning—but no new money has entered to push the bet further.
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).
