When in March 2011 nuclear disaster hit Japan and major corrupted mass media said everything is fine, some smart independent hedge funds and traders were placing bets together worth billions. What they did was very simple, they sold Nikkei 225 futures and bought for the same amount either S&P 500 or Dow, Nasdaq futures pocketing the difference that today equals 15% profit with no risk.
I expect this to continue well into 2012 and this simple long/short index trade will reward you again with minimum 10%. This kind of trade is suitable even for a very conservative investor who otherwise would not trade index arbitrage, but I see it as an opportunity that is hard to resist. Corporate bonds don't pay this much, even junk bonds not, government bonds on the opposite kill the yield with inflation. This is a very low risk trade and is safer than a government bond these days, paying you by the end of December 2012 10% plus. Because both Nikkei 225 (either US$ or JPY traded) and S&P 500, Dow futures are very liquid, you can allocate to this trade even $20,000,000,000 by selling short $10,000,000,000 worth of Nikkei 225 futures traded either in Japan or Singapore (in U.S it's not advised to sell more than $100,000,000 worth of Nikkei 225 futures traded on CME, because big investment banks who are market makers in this product will get to kill you, you are stealing their trade :-) liquidity factor) and buying $10,000,000,000 worth of S&P 500 futures (ES). Now because this is a big trade and will make you many enemies amongst investment banks on Wall Street who will look for ways to kill your trade by manipulating the market short term and make you get out at a loss, that's why use $5,000,000,000 margin for this long/short $20,000,000,000 trade. In 2012 send me a greeting card with best wishes, because your mega hedge fund will be worth at least $2,000,000,000 more. This trade suits both very big and small traders, I am not greedy you make money trading my ideas. I believe if you profit from me, I profit too.
