I'm looking at Fidelity's portfolio performance tab, and my account history is starting to be long enough to be able to view the risk measurements tab.
Of course there is annualized return, but I'm wondering how much should I keep an eye on other metrics such as standard deviation, sharpe ratio, or comparative metrics such as risk-adjusted alpha when comparing to S&P?
Likewise, I have some accounts that are buy & hold/S&P cost averaging, and another account that is focused on options trading. Do these metrics like sharpe ratio/risk-adjusted alpha still apply for options accounts given that the account can swing so much?
For people that do look at this stuff, how do you approach risk management?
