Different investments accounted for $13 trillion in belongings beneath administration (AUM) in 2021, practically twice what it was 2015. By 2026, that determine is anticipated to achieve 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 type to enterprise capital, amongst different alternate options, some fund managers are faring higher than others. Why? As a result of they’ll finesse their investments’ valuations. PE funds don’t have any every day mark-to-market accounting, to allow them to easy losses out throughout a number of quarters.
The ingenuity of this observe is that despite the fact that they’ve related danger publicity PE returns appear uncorrelated to equities. On paper, every thing seems nice.
Correlations are the hallmark of different investments. Producing uncorrelated returns in a yr when the standard 60/40 equity-bond portfolio has posted double digit losses is a fast technique to seize investor curiosity and capital. Nonetheless, 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 information is sourced from HFRX, which has every 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 courses. 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 danger profiles.
Nonetheless, three methods demonstrated low inventory market correlations with out excessive correlations to US investment-grade bonds. This means they could provide some worth for buyers.

Quantifying Diversification’s Advantages
When offered with a spread of different methods, a capital allocator ought to choose these with the bottom correlations to shares and bonds since they display 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 standard portfolio didn’t result in a considerably larger Sharpe ratio.

We subsequent calculated the utmost drawdowns for all of the portfolios. These all occurred throughout the international monetary disaster (GFC) in 2009. Each shares and bonds fell, very similar to they’ve this yr.
Our equity-bond portfolio plunged 35%, whereas our diversified portfolios all declined between 31% and 39%. Such danger discount isn’t notably 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’d anticipate a linear relationship between lowering correlations and drawdowns, not less than till correlations attain zero. In the event that they grow to be too unfavorable, 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 determine 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 usually spike precisely when buyers require uncorrelated returns.
Take merger arbitrage for instance. The technique is usually uncorrelated to equities, however when inventory markets crash, mergers disintegrate. A portfolio with lengthy positions in acquirable firms and quick positions in buying companies could be constructed beta-neutral. However that doesn’t negate financial cycle danger, which can be inherent in shares.
All our seven different methods misplaced cash throughout the international monetary disaster between 2008 and 2009. Convertible arbitrage misplaced much more than equities. That’s fairly an accomplishment for the reason that S&P 500 declined by 53%.

Why else have alternate options failed to enhance Sharpe ratios and cut back drawdowns? As a result of, frankly, they’re horrible at earning money. They might generate engaging returns earlier than charges, however their web returns for buyers have been poor during the last 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 aim, and solely merger arbitrage achieved it. And that technique is just 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 unfavorable actual returns. Inflation is way larger at this time, so the goalposts for these methods have moved a lot additional away.

Correlations alone usually are not sufficient to determine different methods. A extra nuanced strategy is required. Particularly, buyers ought to measure correlations when shares are falling. It will weed out merger arbitrage and different methods which have inherent financial danger.
If calculated appropriately, this could reveal that the majority personal asset courses — PE, VC, and actual property — present the identical danger. They therefore offer limited diversification benefits. We want higher instruments to measure the diversification potential of different methods.
In fact, this doesn’t change the underlying concern: Many methods now not generate constructive returns. The typical fairness market impartial fund, for instance, misplaced 0.4% per yr since 2003.
The case for uncorrelated unfavorable returns isn’t a powerful one.
