Dark Pool Activity Apple September 19 2025
Intro — Earnings Focus
September 19, 2025 was a day where earnings momentum mixed with Fed tailwinds to push U.S. markets into record territory. FedEx surprised with stronger-than-expected results, fueling optimism in the transport sector, while Apple and Nvidia dominated institutional flows. Combined with the Fed’s recent rate cut and extraordinary triple-witching volume, traders face a market brimming with both opportunity and risk today — here’s what it means for traders.
Dark Pool Activity
Apple: three dark pool prints totaling 233,647 shares (~$49.7M) executed at $212.44.
SPY: block of 126,961 shares (~$76.2M) at $600.15.
Quick Take: Institutions are tactically accumulating large tech positions while rebalancing broad-market exposure.
Block Trades
CME reported block activity across futures; specific equity block trade details remain limited in public feeds. Dark pool prints provide a clearer view of stealth institutional flows on an expiration day.

Current News & Events
Market drivers included the Fed’s recent 25bp cut, a Trump-Xi phone conversation on trade and TikTok, and stronger-than-expected earnings from FedEx. These catalysts helped push indices to record closes amid heavy volume.
Quick Take: A trifecta of macro, geopolitical, and earnings news supported institutional risk-taking on Sept 19.
Options / Unusual Activity
Notable flows: CZR puts (V/OI 640.5), SMR puts (~$1.21M premium), AAPL calls (3,325 contracts at $215 strike). Large new positions in KR and TSM observed.
