My comments from Twitter LINK

Interesting take on #Beta.
Significance of early work on #MPT was its application of #Statistics to investments. Slope ("beta") & intercept ("alpha) of #LinearRegression were already ancient concepts then.

Now they are commonly available tools. #Morningstar won't exist without such tools.
Sharpe's claim to fame is the #SharpeRatio that interestingly doesn't depend on MPT - #StandardDeviation can be found directly (& is more stable than beta).
