Great returns, albeit it in the fantasy land of paper trading. Anything is possible in the short term. Long term? Real money? Whole different game.
What specific trades accomplished this? Amazing. If I could make 4 times the amount I have right now I would just quit and go live on the beach. I know several people who seemed to have results like this paper trading and lost 100% of their money in under 2 months when they went to real money. It seems like if it were this easy the MIT/Harvard quant guys would be doing it.
My guess unfortunately is he went belly up. I will play it straight here- I went from 200K to over a million and now am back to 100K after a few years- granted I spent a couple hundred thousand on living expenses, medical expenses, etc. And I personally know three people, and heard from my broker of many more stories, people who pursued options strategies and ended up with as much as 1000% loss (as in, the guy went from 50K to 100K to owing almost a million dollars, broker should never have allowed this of course). The reality is on a long term basis maybe 1 in 100 people can beat the market averages. At least that's how I feel. I need 900% gain to get back to my high water mark so I am trying to decide if I should even try or just give up.
