What are the implications of efficient capital market?

Efficient capital markets imply that asset prices reflect all available information, making it difficult for investors to consistently achieve returns above the market average. This efficiency can lead to optimal resource allocation, as capital is directed towards the most promising investments. However, it may also result in reduced opportunities for investors to exploit mispriced assets, which can limit potential profits. Additionally, the reliance on market efficiency can lead to increased volatility, as prices react quickly to new information.
