Imagine you are a wealth manager who has been asked to assess the investment strategies of a high-net-worth individual, Mr. Smith, who has expressed concerns about market volatility. Mr. Smith displayed a tendency towards overconfidence in his previous investment decisions, which led to significant losses during market downturns. In light of behavioral finance, analyze how Mr. Smith's biases can affect his investment management and the overall portfolio construction process. Discuss practical strategies you could implement to mitigate the impact of these biases while aligning the investment strategy with his risk tolerance and financial goals. Provide specific examples of behavioral finance concepts that influence investor decisions and how these can be addressed in wealth management.
