Cambria Tail Risk ETF(AMEX:TAIL)

TAIL holds a portfolio of primarily cash and US government bonds, but the primary strategy of the fund involves investing one percent of its holdings every month in out-of-the-money put options on the S&P 500 Index. The strategy involves buying more puts when volatility is low and fewer puts when volatility is high. The main purpose behind holding these options is hedging a portfolio against significant negative movement in the value of US equities, commonly referred to as tail risk. Cambria intends to target options that are 0 to 30% out of the money. Buying puts further out of the money reduces the price tag of this hedge, but also lessens the amount of downside protection provided.
