A only in Feb 2016, I was into Alibaba when price hit a near rock bottom at $60 - and I bottled out - on bad news about fake products etc (not relevant to GoPro). Investors dump BABA like a hot potato. Panic struck. I was left behind because I didn't take a reasonable stop-loss. When a stock is near the bottom of the market the usual fear is "OMG.. is it gonna die?!"
Well with GoPro, if it dies the acceptable loss is so favourable. Like on my live platform, 100 shares with stop-loss down at bust level, a margin of only $44 and a loss of $400 for. That's a loss I'd happily take on. I mean this is nothing compared to the worry of Alibaba going from $60 to zero (back in 2016).
At the mo, I'm thinking I'd be stupid not to take the acceptable loss on GoPro. In essence it's a $400 bet that price may double, triple or more in say 1 - 2 years.
