摘要

投资者希望在寻求投资组合回报的同时避免下行风险带来的痛苦。多元化投资组合(尤其是只做多的投资组合)在市场动荡期间提供缓解的能力近年来受到了攻击,许多人说,在投资者最需要多元化投资组合的时候,多元化投资组合就完全消失了。这里的证据表明,经常被重复的“在危机中所有相关性归一”是夸大其词。相反,对投资者来说,多元化与以往一样重要。此外,实现全球多元化投资组合也从未如此容易。虽然全球多元化投资组合在过去并没有消除投资组合下跌的风险,但它已被证明既能提供有意义的下行保护,同时也是一种有效的投资组合;也就是说,为所承担的风险提供足够的回报。

Putting 2020 into Perspective: Diversification May Work Better than You Think
Investors wish to avoid the pain of downside risk while seeking portfolio returns. The ability of a diversified portfolio, especially long-only, to provide relief during market turbulence has come under attack in recent years with many saying that diversification disappears altogether when investors need it most. The evidence here suggests the oft repeated “all correlations go to one in a crisis” is an exaggeration. Instead, diversification remains as relevant to investors today as ever before. Furthermore, achieving a globally diversified portfolio is also never before easier. Although a global diversified portfolio has not eliminated the risk of declines in portfolios in the past, it has been shown to provide both meaningful downside protection while also being an efficient portfolio; that is, in providing a sufficient return for the risk taken.
