URGENT: PYTHON AND DATA ANALYSING QUESTION

Based on standard Portfolio Theory, If and when we define assets to follow normal distribution we are able to describe the asset dynamics in terms of mean and standard deviation as well as co-variances between different stocks and achieve optimal portfolio allocation. In practice however, we do not observe normal distribution when dealing with real-world asset prices or other finance driven time series. Is the Portfolio Theory still applicable for our understanding of the underlying dynamics in asset pricing?

a. True

b. False
