In his 2005 e-book The World Is Flat: A Transient Historical past of the Twenty-first Century, Thomas Friedman famous that the convergence of know-how and occasions allowed India, China and lots of different international locations to change into a part of the worldwide provide chain for companies and manufacturing, “flattening” the worldwide financial system. That flattening led to a major improve within the correlation of returns of U.S. and worldwide shares.
From 1970 via 1989, the correlation of the S&P 500 Index to the MSCI EAFE Index was simply 0.49. From 1990 through1999, the correlation elevated barely, to 0.54. Sadly, over the previous 23 years (2000-2022), the correlation elevated to 0.87. Because the world turned extra built-in and know-how advantages unfold shortly, correlations amongst fairness property rose, decreasing the advantages of world diversification.
One other vital level to contemplate is that in crises, such because the Nice Recession and the COVID-19 pandemic, the correlation of all fairness asset lessons tends to rise towards 1. That leads many to consider that fairness diversification not works. Nevertheless, diversification advantages come not simply from correlations however from the dispersion of returns as properly. As seen within the desk beneath, there was a large dispersion of returns in virtually yearly since 2000—demonstrating that there are nonetheless giant diversification advantages.
The underside line is that whereas there are nonetheless diversification advantages from investing internationally, the advantages have been decreased. That will increase the significance of including different distinctive sources of danger and return to your portfolio, as financial idea suggests, in an effort to scale back the potential dispersion of returns (minimize the tail danger).
The empirical proof, supported by financial idea, means that an funding technique needs to be based mostly on three key ideas: First, markets are extremely, although not completely, environment friendly. That results in the conclusion that lively administration is a loser’s recreation. Second, if markets are environment friendly, it follows that it’s best to consider that every one distinctive sources of danger have comparable risk-adjusted returns. Third, if all distinctive sources of danger have comparable risk-adjusted returns, the logical conclusion is that portfolios needs to be diversified throughout as many distinctive/unbiased sources of danger and return (not simply market beta danger) as you possibly can determine that meet the standards of persistence, pervasiveness, robustness to varied definitions, implementability (survives transactions prices) and possessing intuitive risk- or behavioral-based explanations that present causes for believing the premium ought to persist sooner or later.
With these core ideas in thoughts, there are a number of methods buyers can add different distinctive sources of danger to their portfolios. They’ll improve their publicity to fairness components which have met all of the established standards: dimension, worth, momentum and profitability/high quality. The desk beneath reveals the correlation of returns of those components.
Not solely can buyers diversify throughout components, however via using long-short issue funds, equivalent to AQR’s QRPRX and QSPRX, they will diversify throughout shares, bonds, commodities and currencies as properly, offering additional diversification advantages.
The SEC’s approval of interval funds (with restricted quarterly liquidity) has supplied buyers with the chance to spend money on different distinctive sources of danger (together with illiquidity danger), equivalent to client loans (via such funds as Stone Ridge Asset Administration’s LENDX), reinsurance (via such funds as Stone Ridge’s SRRIX and SHRIX and Pioneer Amundi’s XILSX) and the non-public debt of companies (via such funds as Cliffwater’s CCLFX and CELFX).
Investor Takeaways
The flattening of the worldwide financial system has decreased, although not eradicated, the advantages of worldwide diversification. Diversifying throughout different distinctive sources of danger components and different investments permits buyers to create extra environment friendly portfolios—decreasing volatility, narrowing the potential dispersion of returns and dramatically decreasing the tail danger inherent in conventional 60/40 portfolios.
There actually is nothing new right here. The endowments of Harvard and Yale have been incorporating distinctive sources of danger of their portfolios for many years. And Bridgewater’s Ray Dalio has been touting the advantages of a “danger parity” strategy for many years as properly. Fortuitously, immediately’s retail buyers now have entry to such methods with out having to pay the normal 2 and 20 charges of hedge funds, which go away the fund sponsors with all the advantages. Nor do buyers need to pay the excessive charges of lively managers. Many low-cost ETFs now present entry to the aforementioned components. And the SEC’s approval of interval funds has additionally introduced extra competitors, considerably lowered fund expense ratios and eradicated efficiency charges.
The decreased diversification advantages of worldwide equities and the nonetheless traditionally low yields accessible on the most secure bonds, mixed with elevated entry to lower-cost different investments that present distinctive sources of danger and return, ought to trigger buyers to contemplate growing their allocations to alternate options from the standard 10-15% to perhaps 25-30%—which might nonetheless be properly beneath the allocation to alternate options of, for instance, the Yale and Harvard endowments.
