# That's how the U.S. stock market is.Once the market identifies a theme or concept, such as AI disrup

That's how the U.S. stock market is.

Once the market identifies a theme or concept, such as AI disrupting tool-based software, stock prices in the U.S. market will plummet wildly.

This could, of course, be a misjudgment.

However, do not buy in lightly.

Because you might be catching a "falling knife" (Peter Lynch).

It will keep falling until you despair, making your heart bleed.
