英文摘要:
We discuss - in what is intended to be a pedagogical fashion - generalized \"mean-to-risk\" ratios for portfolio optimization. The Sharpe ratio is only one example of such generalized \"mean-to-risk\" ratios. Another example is what we term the Fano ratio (which, unlike the Sharpe ratio, is independent of the time horizon). Thus, for long-only portfolios optimizing the Fano ratio generally results in a more diversified and less skewed portfolio (compared with optimizing the Sharpe ratio). We give an explicit algorithm for such optimization. We also discuss (Fano-ratio-inspired) long-short strategies that outperform those based on optimizing the Sharpe ratio in our backtests.

中文摘要:
我们将以一种教学方式讨论投资组合优化的广义“平均风险”比率。夏普比率只是这种广义“平均风险”比率的一个例子。另一个例子是我们所称的法诺比率(与夏普比率不同,法诺比率独立于时间范围)。因此,对于长期投资组合而言,优化Fano比率通常会导致投资组合更加多样化,扭曲程度更低(与优化Sharpe比率相比)。我们给出了这种优化的显式算法。我们还讨论了(受Fano比率启发的)多空策略,这些策略在我们的回溯测试中优于基于优化夏普比率的策略。
