What is everyone buying today and why?

Curious what everyone is buying or watching today. Are you adding to long-term positions, taking profits, buying the dip, chasing momentum, or just sitting in cash? Feels like the market has been moving really fast lately and every day there’s a new theme getting attention. AI, semis, small caps, nuclear, copper, space, biotech, defense, crypto names hard to tell what is actually worth buying and what is just another short-term hype trade. I’m trying to build a better watchlist instead of randomly chasing whatever is green. So what are you looking at today? What’s the setup? Why now? Is it a short-term trade or something you’d actually hold? What would make you cut it? No ticker-only comments. Give the reason too.
