"Nasdaq slides as investors dump semiconductors, taking profit after an 80%+ H1 surge" — tech is in active profit-taking with valuations called "overstretched" and a high bar into earnings that don't begin in earnest until ~July 13 (past this window). QQQ just fell three straight sessions (736→725→712.6), breaking momentum, with added AI-infra worries (Meta cloud push, OpenAI IPO delay). Crowd is already heavily short (2/8), so no contrarian bonus, but with no positive catalyst inside the week I side with the downward momentum toward the 706/693 support.
