The Investment Thread

I bought 150 shares of Rivian (RIVN) at $100 on Thursday. Today it briefly hit $150. It's absolutely insane. I intend to hold this for the long term but I had no idea it would get this crazy.

Meanwhile Tesla is down to $986. I'm just wondering how low it will go so I can buy in.
I watched the IPO, but given my history of making bad choices on IPOs I held off on getting any shares, and now I am feeling like it's more of a gamble to get in now...
