Portfolio performance evaluation is the last step in the portfolio management process where the investor examines how well the portfolio objectives have been achieved. It allows the investor to evaluate their own portfolio performance to identify mistakes and improve. Portfolio managers of mutual funds and investment companies also undergo evaluation to assess the performance of the portfolios they manage and their skills. Investors in mutual funds want to evaluate fund performance to select the best performing and lowest risk funds. Portfolio evaluation looks at performance from a transaction, security, or portfolio level perspective with the portfolio level being the best since it considers overall return and risk.
