If you had $10K to invest in a single stock that isn't part of the Mag 7, what would it be?

Beginner here. Bought ASTS at $6 and sold at $9 cause I needed the money a few years ago. I know nobody has a crystal ball and you shouldn't trust people online for your investments but honestly, if you invested in only the top 3-5 stocks that kept getting recommended here (ASTS, RKLB etc.) you'd be doing pretty well.

This post is just for a bit of fun and at my own risk so I'm not looking for any ETF or Mag 7 recommendations, I'm looking for some fun moonshot stocks like ASTS again.
