a friend blipped me this link with no comment, and i said "nah, i'm not going to post there". but i changed my mind.
anyhow...i've been shorting top % gainers - most times intraday, sometimes a couple day short. the initial impetus had been going around in my head for more than 10 years, for when i hadn't traded for too many years, i'd get into some stocks near tops and watch a bunch of them fade. my winners saved me, and made me money, but i've used it for a while.
i have a *ton* of rules i adhere to, some based on fundamentals, some on technicals, for NOT shorting top % gainers. i don't have them written down, but i do a bunch of checking on each stock before i enter it.
if something feels wrong after i'm in a position, where the stock doesn't act as it should, i'll get out. sometimes, i'll be wrong, and it will collapse more. c'est la vie.
it's definitely not for everyone, and because i limit size traded, it's not something that can be expanded out for position. i don't use it as my exclusive trading method - i have a couple other things i do as well. and i'd be more hesitant about doing it in futures or commodities.
oh, CPSL is shortable again at IB. i doubt i'll be shorting it today.
