State Street’s approach measures confidence directly and quantitatively by assessing the changes in investor holdings of risky assets.The idea is simple: the more of their portfolios that sophisticated investors are willing to devote to riskier as opposed to safer investments, the greater their risk appetite or confidence. When risk appetite increases, investors move to increase, in the same proportion, their holdings of each risky investment. This process may occur when there is good news and prices are up, but could also happen over a period of bad news and falling prices. As a result, the risk appetite of institutional investors is a separate and distinct measure from the behavior of prices. Actual investor holdings and recent purchases provide a solid foundation on which to base a measure of investor confidence.
