The rule you always see for asset allocation is always "Subtract your age from 100, and invest that percentage in stocks, the rest in bonds". I understand the general reasoning behind that, but the rule seems so simplistic that I doubt there is much detailed logic behind it. Among other things, it ignores the role early retirement, expected withdrawal rate, expected longevity, etc. might play in determining the proper mix at any given point in time.
For example, it seems a better approach would be "Assume any major market downturn is unlikely to last more than 10 years. Therefore, keep 10 years worth of living expenses in non-volatile investments (bonds), and the rest in stocks".
Any flaws with this approach? Any approaches that make more sense than the Rule of 100?
