Is performance or asset gathering driving growth in hedge fund industry assets? And why does the answer matter to hedge fund investors?

In summary…

In the wake of recent market volatility, even more investors are seeking downside protection from hedge funds, resulting in large inflows into the hedge fund industry. But if we look back at the growth of hedge fund AUM over the past decade, where has the huge growth over the period come from?

  • Hedge fund industry assets have grown by 63% in the past decade.
  • When we look at the hedge fund industry in aggregate, the vast majority of this dollar growth has come from positive performance, rather than net inflows.
  • However, dig a bit deeper and you find that this is not true across the board. When we look at funds individually, only 47% of funds have generated profits that have exceeded net inflows.

According to the Aurum Hedge Fund Data Engine*, hedge fund industry assets have grown by $1.3tn in the past ten years. That’s 63% growth in a decade. Over the same period, the number of actively reporting hedge funds has actually fallen by 19%.

Hedge funds are often criticised for focusing on generating management fee income by accumulating assets through asset raising, often to the detriment of performance generated for their investors. Investment options narrow as assets increase, with larger managers limited to the most liquid investments, and less able to trade around positions.

But has the growth in hedge fund industry assets really come from asset raising/net inflows? Or has the growth come more from positive performance?

Hedge fund industry

Drilling into the data in the Aurum Hedge Fund Data Engine shows that net inflows contributed just 5% to hedge fund industry growth over the period whilst performance contributed 95% of the reported $1.3tn of hedge fund industry asset growth seen over the past decade.

Strategy level

Is the observation the same across hedge fund strategies? P&L growth for all hedge fund strategies monitored by the Aurum Hedge Fund Data Engine exceeded net inflows, with the exception of arbitrage. For some strategies, specifically credit, equity long/short, event driven, long biased, macro, and multi-strategy, performance represents more than 100% of the growth in assets, with these strategies experiencing net outflows in aggregate over the period.

Why has arbitrage been the exception? Subscriptions into arbitrage funds gained momentum after the increased market volatility in March 2020. It’s hard to draw direct conclusions, however it is likely that this, and the subsequent ongoing volatility, has piqued investor interest for non-directional and convexity strategies, like tail protection and volatility arbitrage.

Fund level

So far we’ve looked at the hedge fund industry in aggregate, and the trends when we look at hedge funds grouped into strategies. But if we drill down even further to the individual fund level, it’s quite a different picture. Only 47% of individual hedge funds have generated profits that have exceeded net inflows in the past decade. Only 71% of individual hedge funds have had cumulative positive net returns over the decade.

As mentioned above, the hedge fund industry is often criticised for accumulating investors’ assets in order to collect management fees, delivering lacklustre performance in return. However, breaking down the growth in the industry into performance generated and net subscriptions tells a different story at the headline level. Hedge fund growth in almost all strategies over the past decade has been predominantly performance-driven, i.e. growth has been predominantly organic.

But, decomposing the asset growth of the hedge fund industry in aggregate, or even by strategy, masks the role of individual funds in these trends. Despite performance representing 95% of the growth in hedge fund industry assets over the past decade, only half of funds made profits that exceeded net inflows over that period.

Rigorous due diligence and manager selection is critical for hedge fund investors. There are no shortcuts when analysing hedge funds, but the benefits are there for investors that are able to put in the significant investment in time and knowledge that is required.
