AMD rose 10.5% on Monday. The off-exchange tape says it was not a crowd trade. Our dark pool screen scored it 83 for stealth accumulation: off-exchange volume rose while the short share of that volume fell. MSFT 82. NVDA and GOOGL stayed neutral at 66. signumhq.com/app?from=bluesky

NVDA closed at 227. Its call wall — the strike holding the most call open interest into Friday — is 230. Three dollars. That is not a prediction. It is where the contracts are stacked, and it is the kind of thing worth knowing before the open. signumhq.com/app?from=bluesky

"Dark pool volume spiked" usually is not dark pools. FINRA reports two buckets: ATS (actual dark pools) and OTC non-ATS — wholesalers internalizing retail orders. The second is often bigger. And a print tells you where a trade cleared, not who was the aggressor. signumhq.com/app?from=bluesky

"Up 7% after hours" is not the number you see at the open. After-hours % is measured against today's 4pm close. Premarket % is measured against yesterday's close. The ruler changes overnight. A red premarket print after a green after-hours one is often just that. signumhq.com/app?from=bluesky
