Berkshire Hathaway has realized a Sharpe ratio of 0.76, higher than any other stock or mutual fund with a history of more than 30 years, and Berkshire has a significant alpha to traditional risk factors. However, we find that the alpha becomes insignificant when controlling for exposures to...

The prices of Greek closed-end funds behave similarly to the prices of US funds: they deviate substantially from their net asset values (NAVs); they are more volatile than their NAVs; and they are overly-sensitive to the movements of the domestic stock market index. Furthermore, their premia...
