My name is Preston Yadegar and I'm a sophomore at Boston University in our quant research team within our Finance Club on campus. After reading several posts and responses, I see that of the portfolio metrics Sharpe is more desired than Alpha. If someone produced an algorithm which could generate great Alpha but a standard Sharpe (near 1), what could they do to translate the Alpha into a better Sharpe ratio? I was thinking about this and I think simply reducing leverage could help (by reducing the volatility of portfolio returns). Are there any other tactics we could broadly apply to strategies to translate Alpha into Sharpe? Also, what factors does Quantopian use when calculating Alpha? As I understand it, Alpha is the excess portfolio return unexplained by factors like market returns; are there any other factors used (like oil, gold, etc.)?
