Explanation:
The graph illustrates a gradual adjustment of the stock price following the release of public information, rather than an instantaneous jump to a new equilibrium. This delayed reaction indicates that the market is not semi-strong form efficient. In a market that is inefficient at the semi-strong level, active portfolio managers can exploit the slow incorporation of public information into stock prices to generate risk-adjusted excess returns (alpha). Therefore, active management may indeed result in excess return. Passive management, which simply aims to replicate market returns, would not specifically exploit this inefficiency.
