First post — my painful lesson on conviction sizing

Hey everyone, just joined. My biggest lesson, learned the hard way last year, was around conviction sizing. I had a really strong fundamental read on $MSFT for a bounce, but sized it like a typical swing trade, only to watch it run without me having meaningful exposure. Conversely, I sized an iffy $AMD short much larger because 'it felt right,' only to get squeezed hard. Learning to match conviction with appropriate position sizing is an ongoing battle.
