In the past, you only needed to remember one phrase: “A historic plunge = a golden buying opportunity”

It was ripped up in the early hours of November 6: the Nasdaq 100 closed down 6.36%, wiping out $2.3 trillion in a single day—the biggest drop since March 2020—and falling nearly 15% from its October peak; the Philadelphia Semiconductor Index plunged 12.25% into bear-market territory, while the VIX surged 70% to 28.18.

Don’t rush to slap a “golden buying opportunity” label on it.

Consider three things:
① Selling pressure hasn’t run its course—UBS warns that systematic funds will sell more than $100 billion on Friday, and “this correction may not have bottomed yet.”

② This is a repricing of policy—Democratic lawmakers have said that “the top priority on the first day of the next Congress will be to pause advanced AI development.” Meanwhile, Texas, where 27% of all planned US data-center capacity is located, elected its first Democratic governor in more than 30 years whose central campaign promise was to pause approvals.

③ Key technical levels have all broken—the Nasdaq fell below its 200-day moving average, and the spot-futures basis widened to its largest gap since April.

In plain English: federal legislation still has to get past a presidential veto, so the real thing to watch is the states. Texas accounts for 27%. Yesterday, investors sold stocks that had become too expensive; today, they’re selling risks they can’t stomach. This isn’t an accident—it’s a repricing.

How much does this have to do with your portfolio?
Three moves:
Don’t catch a falling knife: before the $100 billion in selling pressure hits, any rebound is a chance to sell.

Check your positions: momentum ETFs plunged 8.2% in one day, their worst drop since 2020, while QQQ volume was 100% above its 20-day average. Crowding is your risk exposure.

If you’re looking to buy the dip, wait for three signals: the VIX falls back from 28, the $100 billion in selling pressure is absorbed, and there’s news on Texas legislation.

Risk warning: the Nasdaq Golden Dragon China Index rose 0.43% against the trend—money is looking for an exit. Don’t mistake “down a lot” for “cheap.” There’s only one signal to admit you’re wrong: the VIX quickly falls below 20, or Democrats publicly clarify that the ban is only posturing. Either would invalidate the defensive thesis.

Checkpoints: systematic fund-flow data next week and progress on legislation in the Texas state legislature.

This isn’t a bubble bursting—it’s the first time someone has pulled the plug on “AI that never runs out of steam.”

The direction is clear: stay defensive in the short term and wait for selling pressure to run its course. We’re not at the edge of the golden buying opportunity yet.
