The S&P 500® Risk Control 10% Indices offer investors greater stability and a reduction in the overall risk level of the S&P 500, widely regarded as the best single gauge of the U.S. equities market. By integrating a volatility control within the index rules, Standard & Poor’s provides a new level of innovation for investors looking to gain exposure to the U.S. equity markets while limiting their risk. Currently, S&P Indices offers four risk controlled versions of the S&P 500.

The S&P 500 Risk Control Indices utilize the existing S&P 500 methodology, plus an overlying mathematical algorithm designed to control the level of risk of the index by establishing a specific volatility target and dynamically adjusting the exposure to the S&P 500 based on its observed historic volatility.

S&P 500 Risk Control Indices include:

• S&P 500 Risk Control 10% Index
• S&P 500 Daily Risk Control 5% Index
• S&P 500 Daily Risk Control 15% Index
• S&P 500 Monthly Risk Control 12% Index

  S&P 500 Daily Risk Control 5% Index	The S&P 500 Daily Risk Control 5% Index represents a portfolio consisting of the S&P 500 Index and a cash component accruing interest based on LIBOR. The index is dynamically adjusted to target a 5% level of volatility. Volatility is calculated as a function of historical returns that uses exponential weightings to give more significance to recent observations.  In addition, a short and long term measure of volatility are used to cause the index to deleverage quickly, but increase exposure more gradually on a relative basis. The index rebalances daily.
