Fantasy-Busting: Alts’ Uncorrelated Returns Diversify Portfolios

Shattered Windshield

Introduction

Different investments accounted for $13 trillion in belongings underneath administration (AUM) in 2021, practically twice what it was 2015. By 2026, that determine is predicted to succeed in greater than $23 trillion, according to Preqin research. Increase occasions are right here for enterprise capitalists, personal fairness (PE), and hedge fund managers.

Though 2022 hasn’t been sort to enterprise capital, amongst different options, some fund managers are faring higher than others. Why? As a result of they will finesse their investments’ valuations. PE funds haven’t any each day mark-to-market accounting, to allow them to easy losses out throughout a number of quarters.

The ingenuity of this observe is that although they’ve related threat publicity PE returns appear uncorrelated to equities. On paper, the whole lot appears to be like nice.

Correlations are the hallmark of other investments. Producing uncorrelated returns in a yr when the normal 60/40 equity-bond portfolio has posted double digit losses is a fast solution to seize investor curiosity and capital. Nevertheless, correlations are like icebergs floating within the sea, there’s a lot hiding beneath the floor.

So simply what are the pitfalls of utilizing correlations to decide on different methods?

The Different Champions

To seek out out, we chosen seven well-known methods from the hedge fund universe which have attracted billions from capital allocators. Our knowledge is sourced from HFRX, which has each day returns going again to 2003. This practically 20-year interval covers a number of market cycles when different methods ought to have demonstrated their worth by offering diversification advantages.

We calculated these hedge fund methods’ correlations to conventional asset lessons. Three of those methods — fairness hedge, merger arbitrage, and event-driven — have S&P 500 correlations in extra of 0.5. It wouldn’t make a lot sense so as to add these to an fairness portfolio given their related threat profiles.

Nevertheless, three methods demonstrated low inventory market correlations with out excessive correlations to US investment-grade bonds. This means they could supply some worth for buyers.

Quantifying Diversification’s Advantages

When offered with a variety of other methods, a capital allocator ought to choose these with the bottom correlations to shares and bonds since they show the very best diversification potential.

To check this speculation, we sorted the seven hedge fund methods by their common correlations to shares and bonds and ran simulations that added a 20% allocation to every technique to a 60/40 equity-bond portfolio after which rebalanced on a quarterly foundation.

Opposite to expectations, including an alternate allocation didn’t enhance the Sharpe ratios for the 2003 to 2022 interval.

What’s much more uncommon is that there doesn’t appear to be any relationship among the many correlations. For instance, merger arbitrage had the next common correlation to shares and bonds than fairness market impartial. But including the latter to a conventional portfolio didn’t result in a considerably greater Sharpe ratio.

We subsequent calculated the utmost drawdowns for all of the portfolios. These all occurred in the course of the international monetary disaster (GFC) in 2009. Each shares and bonds fell, very like they’ve this yr.

Our equity-bond portfolio plunged 35%, whereas our diversified portfolios all declined between 31% and 39%. Such threat discount isn’t significantly spectacular.

However as with our earlier Sharpe ratio evaluation, the utmost drawdowns didn’t fall additional when extra diversifying different methods had been added.

We might count on a linear relationship between lowering correlations and drawdowns, a minimum of till correlations attain zero. In the event that they develop into too adverse, as with a tail risk strategy, then diversification advantages deteriorate once more. We’re anticipating an sad smile, however nobody is smiling.

So, are correlations failing buyers of their efforts to establish helpful different methods?

Truthful Climate Correlations

One partial clarification for our outcomes is that correlations are deceiving. Even when they’re near zero on common, there nonetheless could also be intervals of excessive correlation. Sadly, correlations typically spike precisely when buyers require uncorrelated returns. 

Take merger arbitrage for example. The technique is often uncorrelated to equities, however when inventory markets crash, mergers crumble. A portfolio with lengthy positions in acquirable firms and quick positions in buying companies may be constructed beta-neutral. However that doesn’t negate financial cycle threat, which can be inherent in shares. 

All our seven different methods misplaced cash in the course of the international monetary disaster between 2008 and 2009. Convertible arbitrage misplaced much more than equities. That’s fairly an accomplishment because the S&P 500 declined by 53%.

Why else have options failed to enhance Sharpe ratios and cut back drawdowns? As a result of, frankly, they’re horrible at being profitable. They could generate engaging returns earlier than charges, however their web returns for buyers have been poor over the past 19 years.

The S&P 500 produced a CAGR of 9.5% for the 2003 to 2022 interval, however that isn’t the precise benchmark for hedge fund methods. Beating bonds is a extra cheap objective, and solely merger arbitrage achieved it. And that technique is simply too strongly correlated to equities to supply a lot in the best way of diversification.

Inflation was roughly 2% for this era, so CAGRs under that suggest adverse actual returns. Inflation is way greater immediately, so the goalposts for these methods have moved a lot additional away.

Additional Ideas

Correlations alone are usually not sufficient to establish different methods. A extra nuanced method is required. Particularly, buyers ought to measure correlations when shares are falling. This can weed out merger arbitrage and different methods which have inherent financial threat.

If calculated appropriately, this could reveal that almost all personal asset lessons — PE, VC, and actual property — present the identical threat. They therefore offer limited diversification benefits. We want higher instruments to measure the diversification potential of other methods.

In fact, this doesn’t change the underlying difficulty: Many methods not generate optimistic returns. The common fairness market impartial fund, for instance, misplaced 0.4% per yr since 2003.

The case for uncorrelated adverse returns isn’t a powerful one.
