Brokerage houses, funds, all those guys have power through nite. Go away with the seller being KT, so stupid. He plan sales 500k blocks. If you get a job trading fresh out of grad school your entry level job will generally find you at the helm of a million dollars in cash to trade with.
There arent really rules. If you lose a half million you go bye bye. If you make 5 million betting on pennies, you get recognition. everybody wants the big office so it's as cut throat as anywhere. The more boutique agencys are pretty hands off. They hire good people and let it rip. Its not like they have a pork belly desk at hedge funds. I wouldn't be surprised if there was someone within a hedge fund involved in the trading.
