When Hindsight Becomes Foresight: Replicating Investment Performance

Introduction

We now have analyzed dozens of private and non-private market funding methods, corresponding to merger arbitrage and personal fairness, respectively, over the previous few 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 sophisticated wrappers. As soon as the tide goes out, the danger publicity is similar in every single place.

We will show 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 scarcity of diversification advantages.

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

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

To show 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 nearly 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 monitor document was too brief to attract any conclusions and that our replication course of was merely primarily based on hindsight. These had been honest factors, so we expanded our evaluation.

Lengthy–Brief Fairness Hedge Fund Efficiency

Because the purpose is to duplicate equity-like returns with much less threat, 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 Brief Equities Hedge Fund Index and HFRX Fairness Hedge Index each have 20 years of historical past, which needs to be adequate.

However Eurekahedge has a CAGR of 8.1% versus 2.0% for HFRX. On condition that each mixture the returns of single lengthy–brief fairness hedge funds, such a big discrepancy is alarming and makes it tough to judge 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 monitor information 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 smart to disregard the Eurekahedge index and focus, as we do in the remainder of our evaluation, on the extra reasonable HFRX.

Replicating Lengthy–Brief 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 ends in considerably greater risk-adjusted returns for the replication portfolio.

To make sure, traders don’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, would possibly our evaluation nonetheless be primarily based 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 supply 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 draw back. 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.

Sooner or later, hindsight turns into foresight.
