Sigh. Here's the truth, everybody knows a guy at work who claims they make money "day trading."
If you know more than 1 person who beats the market consistently by trading, you should open a fund-of-funds and start investing institutional money, ASAP. The Harvard endowment would love to speak with you.
This is absurd. You don't know my friends, and you say they are lying?
Daytrading for a single account and managing a multi-billion dollar fund are completely different strategies and need completely different skillsets. You should educate yourself before talking authoritatively on subjects you don't know very much about.
