How the index fund industry began.
Since ProShare Advisors launched its first inverse ETFs in June of 2006, hedging your portfolio has never been easier. Little wonder that the Bethesda, Md.-based money manager has garnered a whopping $16 billion in assets in less than two years. All you have to do is buy the Proshares Short S&P 500 ETF (AMEX: SH) and your portfolio is protected from any market downdrafts, which lately have become very drafty indeed.
