Dark pool share: 40% off-exchange — 9pp 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: 45% vs a 53% norm.

What it means: MOS shows quiet institutional accumulation off-exchange (17% above normal volume, short-selling down 7.9 points vs. the stock's norm), signaling patient buying despite a bearish news backdrop. Standing option positions lean bullish (more calls than puts), though recent traded flow is balanced and squeeze pressure is low.
News vs the money

News is bearish (share price pressure from import competition), yet the money shows institutions buying quietly off-exchange at reduced short-selling levels—a classic divergence suggesting smart money sees the dip as temporary or the long-term story as intact.
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.
