Investors' biases can affect how they make decisions about buying and selling investments, but it's hard to measure these biases accurately. Traditional financial models don't consider these biases, but a new mathematical framework is being developed to help understand and quantify them. This framework aims to help investors optimize their portfolios by taking into account their behavioral biases. Noise in the financial market makes it challenging to identify the factors driving market behavior, but this new model could help in making better investment decisions.
