All measures of investment risk I've seen rely on volatility. If the market drops suddenly, that's considered more risky than the absence of a market drop. Yahoo shows R squared, standard deviation, Sharpe ratio, and Treynor ratio. For example, the S&P 500:

In theory, if an investment makes +50% more with +100% more volatility, it's "more risky". But this risk, as I understand it, is about selling after a market drop, and missing out on the gains in a recovery. In both the dot-com crash and 2008 crisis, many investors sold while I kept my investments. So does that mean investors can be sorted by risk tolerance? Do many investors gain more risk tolerance over time?
Looking at an R squared or Sharpe ratio, despite investing for decades I don't know what it means to me. It seems like the use of volatility to measure risk seems rather incomplete. I wish there was a better definition that included both investor and the investment.
