Is $QQQ at 732.9 getting ahead of itself on tech momentum?

Watching $QQQ today, hitting 732.9 after that nearly 1.3% jump. It's been a monster run, obviously, and the underlying tech strength is hard to argue with. But with the high of the day at 733.75, I'm starting to wonder if we're seeing a bit of 'mania' kicking in, especially as it feels like the broader market isn't quite as universally strong. Are we just chasing momentum here, or is there a genuine, fundamental reason for this pace that I'm missing? I'm curious to hear if others are thinking similarly, or if I'm just being overly cautious.
