back to basics: why does a longer time horizon imply a greater risk tolerance?
I realize that w a longer time horizon, we have more time to recover from losses.
but. intuitively, just because I have a longer time to recover, doesn't mean i like it any better!
take for example an endowment that's intended to spend itself out of existence in 10 years or less.
intuitively, I'd say screw it, rite? I only got 10 years, let's rock and roll! let's live a little, get ourselves nice risky assets w. juicy returns. but noooo, apparently, short horizon, so must be risk averse.
does this time horizon business actually have anything to do w. volatility? given that volatility grows @ the rate of sqrt (time), this actually reduces volatility estimates w. longer time horizons.
so could one conclude that, ceteris paribus, longer time horizon == smoothed / lower volatility estimates ====> essentially higher Sharpe ratio, and therefore you're basically getting a better deal for your risk, and THAT is what actually makes you less risk averse? |
