Why Investors Care
Conventional wisdom suggests investors are confident when stocks are rising and pessimistic when falling. But in fact, the State Street group notes prices tend to be higher when economic fundamentals are strong; i.e., when economic indicators are growing at a healthy clip. But a good investor confidence measure "should indicate whether, for a given set of fundamentals, investors are bullish or bearish on risky assets." State Street believes direct measurement, rather than a survey of portfolio managers who often don't have time to fill out monthly questionnaires, is a more reliable approach to consumer confidence. The investor confidence index is compiled with techniques based on modern portfolio theory. According to State Street, "the more of their portfolios that professional investors are willing to devote to riskier as opposed to safer investments, the greater their risk appetite or confidence." So when investors choose to increase their holdings of risky assets, this confirms their confidence has increased. Incidentally, State Street believes investor confidence can exist in a bear market as well as a bull market. Since market players have become so enamored with consumer attitude surveys, it probably would be useful for both professional portfolio managers and amateur investors to consider investor attitudes.
