The Nasdaq 100 $QQQ just closed right under its 200-day moving average.

This is one of those lines people watch. When price sits below it, the mood shifts. Bulls get cautious. Bears get louder.

It's not a magic line, but it matters because enough traders believe it matters. Self-fulfilling, in a way.

Watch how it behaves here. Does it bounce back above quickly? Or does it keep sliding and turn that level into resistance?

The 200-day has been a decent barometer for whether we're in a healthy uptrend or something messier. Right now, we're in the messy zone.
