FYI: The recency effect—that the most recent observations have the largest impact on an individual’s memory and, consequently, on perception—is a well-documented cognitive bias. This bias could impact investment behavior if individuals focus only on the most recent returns and project them into the future. Such behavior may lead investors to experience a reduction in their risk tolerance (which, in turn, can lead to selling) after a bear market, when valuations are lower and expected returns are higher. Conversely, recency may lead investors to experience an increase in their risk tolerance (which, in turn, can lead to buying) after a bull market, when valuations are now higher and expected returns are lower.
