The Problem with Optimal f
What does “optimal” mean, anyway? In the first part of this series, we discovered that the staked fraction of capital that yields the greatest compounded returns also yields a less-than-optimal level of drawdown. To realize the greatest return on capital, an investor in SPY since its inception should have used over 3x leverage to buy in. This would have yielded the greatest compounded rate of return, but would have induced a 97% (!!!) max drawdown along the way. Since a 20% retracement from peak equity causes most investors to start tossing in their sleep, this approach doesn’t seem very realistic. This post will help traders maximize their gains while still getting their beauty rest!
