We propose a concept of intraday overreaction characterized by intraday price movements which are corrected within the same trading day. It is a concept of relative overreaction in the sense that the price range within a trading day is large in comparison with the openclose return volatility.

Price volatility and investor overreactions are commonplace in experimental asset markets.
