Dark pool share: Off-exchange volume was quiet at 0.7× its norm
Off-exchange prints never touch the public book, so they move size without moving the quote. That is the point of using them. Large players were quiet in this name that day. The share (42.1%) may look normal, but the absolute size behind it was thin.

What it means: Options positioning leans toward more calls than puts on standing positions, but recent traded volume leans defensive with more puts than calls. Off-exchange activity is near its norm with no clear accumulation or distribution signal, so the money picture is mixed.
News vs the money
CarMax shares are down 5.8% since its Q2 earnings report; is it a buy, sell, or hold?
The news points to a mixed picture of higher sales and margin pressure, while the money signals are mixed too, with standing positions leaning call-heavy and recent volume leaning put-heavy.
Zacks Investment Research · 10/08
CarMax shares fell 4.2% in Wednesday trading, trading as low as $56.25.
The drop is a price move without a clear match in the positioning data, and recent volume leaned toward puts, which agrees with the decline rather than contradicting it.
Defense World · 10/02
Zacks rates CarMax as a strong value stock based on its style scores.
The rating is a valuation view, and the money signals do not clearly confirm or challenge it.
Zacks Investment Research · 10/01
Is CarMax a buy after its latest earnings report, given the stock jumped and then slipped back below its pre-earnings price?
The stock slipping back below its pre-earnings level fits the put-heavy recent volume, while standing call positions point the other way.
The Motley Fool · 09/30
CarMax will hold a Strategic Update webcast on November 3, 2026, from 8:00 to 9:30 a.m. ET.
This is a scheduled company event, and the current positioning data does not show a clear reaction to it.

What is a “divergence”?
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).
