Dark pool share: 26% off-exchange — 25pp below the market
Off-exchange prints never touch the public book, so they move size without moving the quote. That is the point of using them. Most of the day cleared on the lit market — either there was nothing to hide, or the large players sat out. Short share of the off-exchange piece: 62% vs a 54% norm.

What it means: CNK's options market shows a call-heavy lean (0.7 put-to-call ratio) with minimal squeeze pressure, but positioning is thin—no new large option positions opened yesterday, and off-exchange volume sits slightly elevated at 1.11x normal with a modest short bias (62% vs. 54% norm), suggesting cautious institutional handling rather than conviction either way.
News vs the money
⚡ DIVERGENCETheater stocks rally amid short-squeeze talk
News frames a squeeze story, but the money shows almost no squeeze tension (score of 5) and call-heavy positioning without fresh large bets, so the rally appears driven by sentiment, not forced covering.

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.
How to read these numbers
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).
