What was your dumbest investment decision?

I'll start: I sold VFV at a loss once 🤡

Oh yeah and i sold AAPL right before its recent run up... On WS... at a loss...

A couple more:

Sold NUVEI @100, DCBO @79.99, LSPD @90, all of them literally like the Friday or so before they all started doing their thing the following week or two

Sold all big 5 banks under $100, list goes on. I'm dumb

The AAPL one is definitely my worst though 🪦🪦🪦
