Yes except you are missing the simple fact that you cannot find anything that will double your money with only a 10% chance of losing it. If you are willing to accept a 50% chance of losing it then there are plenty of ways to meet your double or nothing requirements. Someone with $1,000,000 would love to place 20 $50k bets on such a proposition...just think what kind of return a fund manager would have with those odds...you are not thinking logically.
if this is true do like that guy from london and put it all on red...his entire life savings he sold everything and banked it...
It is much harder to find that many double or nothing opportunities in the market place. It is also harder for a fund manager due to liquidity issues. I think if one is careful and with proper execution, you can find 90% win and 10% losing trades with great pay off, if you are a small time trader.
Buy a brick of crack - 90% you'd double your money in a year, downsides are potential prison term and drive by "attention" for taking over someone elses territory
I'll humor the troll. Buy an SPX DNT 1300/1600 with a Mar 3, 08 expiration. $8,500 pays $50,000 if neither barrier is hit. The pricing is accurate/executable. Rinse, repeat.
