After this pullback ends, most sectors will launch the largest-level uptrend wave of this bull market, and the gains will make your head spin.

This is determined by the trend laws of large-cycle K-line patterns, and you can tell at a glance how things should move normally.
I'm not buying anything now and patiently waiting until the end of April. After the major pullback ends, I'll average down. It's only more than 20 trading days anyway.
That's when it will be raining gold everywhere.
Expected downside for each variety in this major pullback:
Innovative pharmaceuticals, media, baijiu, satellite communications, Hang Seng Tech: 10%
Gold industry, semiconductor materials: 20%
These are ETFs, not futures or stocks. Even if they drop 80%, there's no need to cut losses—just average down.
