Deep Dive into Today's Dark Pool and Option Flow; June 22, 2026
Apologies in advance that this report is late - just fine tuning production and making it more balanced.
Executive Summary
The dominant story today is a bifurcated institutional position in Cadence Design Systems, with floor-executed puts totaling $92.1M at the Sep26 and Aug26 370 strikes sitting alongside a $16.5M floor-executed call buy at the 400 strike - classic collar or hedge-versus-long structure, not a clean directional bet. Micron is the single largest bull theme with over $120M in notional across Dec27 1500 calls, short puts, and near-term structures, and a $277M dark pool buy in AMAT alongside a $342M dark pool buy in AMD reinforces the semiconductor bull bias in the tape. The IGV put buy ($10.8M floor, Aug26 90 strike) alongside SNPS put buys ($10.3M floor, Sep26 400) and the AMD put buy signal a real pocket of software and semi hedging that cuts against the primary bull read. Dark pool shows aggressive selling of broad index ETFs in size - IVV, VOO, SPY combined north of $7.8B - paired with targeted single-name buying in STX, AMD, and AMAT, suggesting rotation out of passive exposure into specific tech names rather than outright risk-off.
