Nasdaq 100 Gives Back Every Gain, Sinks Into the Red After $1 Trillion Wipeout

The Nasdaq 100 couldn't hold the line. The index erased all of its gains for the day and tipped into negative territory, according to The Kobeissi Letter. The damage came fast: roughly $1 trillion in market cap disappeared over a span of about five hours.

That's a full round trip inside a single session. The index had been higher, then handed every bit of it back, flipping from green to red before the day was done. The scale of the swing is what stands out — a trillion dollars is not a wobble, it's a stampede for the exits.

The Nasdaq 100 is the market's tech-heavy scoreboard, tracking the 100 largest non-financial companies listed on the Nasdaq exchange. When it lurches, megacap technology names are almost always the ones doing the lurching.

The Kobeissi Letter put the five-hour loss at -$1 trillion in market cap, framing it as a full reversal rather than a slow bleed. No cause was cited in the report, and the index's move spoke for itself.

Now the question is where it settles. Traders will be watching whether the red holds into the close or whether buyers step back in — and whether the broader market follows the Nasdaq 100 down.
