Who's trader's best friend?
Trader's best friend is other people's hope.
You ride the stock up with those hoping to reap excessive return overnight, like OVTI 's pre-ER, or buyout-rumor run. Then you get out before the judgement time of their hope.
You ride the stock down when those hopes burst, like today's DNDN.
The bigger the hope the better.
"Don't bet on hope" is no longer a trading tip as mundane as "control your loss".
Make it the first principle for your survival in the market.
