  • The results of performance attribution can provide valuable insights into the sources of risk and return in an investment portfolio. By understanding the contribution of asset allocation, security selection, and other factors to the portfolio's overall performance, portfolio managers can make informed decisions about how to adjust the portfolio's composition and investment strategy to optimize the risk-return profile. For example, if performance attribution reveals that a significant portion of the portfolio's return is attributable to a particular asset class or investment strategy, the portfolio manager may choose to increase the allocation to that asset class or strategy to enhance the portfolio's overall performance. Conversely, if performance attribution identifies areas where the portfolio is underperforming, the portfolio manager can take steps to address those issues and improve the portfolio's risk-adjusted return.
