Recent research demonstrates that comovement can be due to both the trading patterns of noise traders and underlying economic fundamentals. As comovement can be measured much more accurately than expected returns, it can be used to identify securities for which the influence of noise traders is high and thus the securities most likely subject to mispricing. Analysis of comovement is a screening device that can provide important information about potential mispricing.
