When Hindsight Becomes Foresight: Replicating Investment Performance

Introduction

We have now analyzed dozens of private and non-private market funding methods, comparable to merger arbitrage and personal fairness, respectively, over the previous couple of years, and one widespread theme has emerged. Many of the merchandise described in additional than 300 analysis papers merely present publicity to the inventory market in difficult wrappers. As soon as the tide goes out, the chance publicity is similar in all places.

We are able to reveal this phenomenon in numerous methods. The commonest method is to easily run an element publicity evaluation. Funding merchandise marketed as providing uncorrelated returns usually exhibit excessive betas to the inventory market, which highlights a lack of diversification benefits.

However there may be a good less complicated and maybe extra highly effective method to illustrate this level: through the use of a mix of the S&P 500 and money to copy the historic efficiency of an funding product with the identical stage of danger.

We lately created Time Machine, a freely accessible software with which buyers can replicate the efficiency of any mutual fund, exchange-traded fund (ETF), or US inventory utilizing simply the S&P 500 and money.

To reveal Time Machine’s facility on social media, we analyzed the iMGP DBi Hedge Technique ETF (DBEH), which tracks the 40 main lengthy–brief fairness hedge funds, and located that an 81% allocation to the S&P 500 and a 19% allocation to money would have delivered virtually the identical efficiency with the identical volatility.

From our perspective, these Time Machine outcomes known as the utility of this ETF into query. A revered Twitter commentator, then again, countered that the fund’s three-year observe file was too brief to attract any conclusions and that our replication course of was merely based mostly on hindsight. These had been honest factors, so we expanded our evaluation.

Lengthy–Quick Fairness Hedge Fund Efficiency

For the reason that purpose is to copy equity-like returns with much less danger, or precisely what a S&P 500 plus money portfolio supplies, we use lengthy–brief fairness hedge funds as case research. To guage every, we chosen indexes which have prolonged histories throughout a number of market cycles. The Eurekahedge Lengthy Quick Equities Hedge Fund Index and HFRX Fairness Hedge Index each have 20 years of historical past, which ought to be adequate.

However Eurekahedge has a CAGR of 8.1% versus 2.0% for HFRX. On condition that each combination the returns of single lengthy–brief fairness hedge funds, such a big discrepancy is alarming and makes it troublesome to guage every technique’s attractiveness. Which one is healthier?

In fact, the variety of funds in every index varies, however the essential driver could also be that Eurekahedge permits new fund managers to import their previous observe data as soon as they begin reporting. Since solely fund managers with good previous efficiency ask to be included in these indexes, a type of survivorship bias could also be at work. So, capital allocators could be clever to disregard the Eurekahedge index and focus, as we do in the remainder of our evaluation, on the extra real looking HFRX.

Replicating Lengthy–Quick Hedge Funds

The HFRX Fairness Hedge Index’s volatility was 6.1% over the 2003 to 2023 interval, which we might have replicated with a 52% allocation to the S&P 500 and 49% to money. However the replication portfolio’s CAGR would have been 3.7% in contrast with 2.0% for the hedge funds, and the drawdown would have fallen from 31% to 19%. This leads to considerably greater risk-adjusted returns for the replication portfolio.

To make certain, buyers wouldn’t have to conduct any due diligence on the S&P 500, whereas hedge fund evaluation is an costly course of that requires an preliminary evaluation in addition to ongoing monitoring. Moreover, an S&P 500 ETF at this time has principally zero bills, whereas hedge funds include excessive administration and efficiency charges. So, who wouldn’t favor the replication portfolio?

Additional Ideas

Though a easy S&P 500 and money portfolio would have achieved greater absolute and risk-adjusted returns than lengthy–brief fairness hedge funds, may our evaluation nonetheless be based mostly on hindsight and have little relevance for anticipated returns?

Sure, however given the 0.71 correlation between the HFRX Fairness Hedge Index and the S&P 500, there may be little query that lengthy–brief fairness hedge funds provide diluted fairness publicity.

Moreover, the HFRX index’s upside beta to the S&P 500 was 0.16 in contrast with 0.25 on the downside. As such, fairness hedge funds observe falling shares greater than rising ones. Clearly, this ratio is at parity for any S&P 500 and money mixture.

In some unspecified time in the future, hindsight turns into foresight.
