iBillionaire - an iphone app and index that lets you track the investments of popular billionaires. It purports to offer a snapshot of where the most successful investors are putting their money. The company behind the concept hopes to follow up with an iBillionaire exchange-traded fund. The ETF would allow regular investors to buy shares in a portfolio that tracks the index, effectively putting their money where the billionaires mouths' are. According to iBillionaire, its own index would have outperformed the S&P 500 by 9.23 percentage points in the last year. Skeptical?
