Waiting out tech weakness cost money on October 20, 2026: the Nasdaq 100 erased its session decline and flipped green, recovering $550 billion in market cap in 45 minutes, according to The Kobeissi Letter. Sidelined traders who moved aggressively into tech on the morning dip caught the entire reversal.
Institutional buyers stepped into the pronounced intraday dip before retail investors could react, which makes exiting on short-term weakness expensive.
The reversal is a reminder of how quickly sentiment can shift in large-cap tech. Morning sellers who acted on the early decline found the floor pulled out from under their thesis within the same trading session.
The episode reinforces a pattern that has defined tech trading in recent cycles: pronounced intraday dips tend to attract institutional buyers before retail investors can react, making it costly to exit on short-term weakness.
