Alternative Title: The Gap Everywhere
There exist many flavors of market timing.
Some are obvious:
On dollar-weighted basis, equity mutual fund investors under-perform buy-and-hold by 6.2% per year during the past 30 years.
ETFs investors under-performing buy-and-hold by -2.28% per year between 2010 and 2016.
Individual stock investors give up -1.3% per year between 1926 to 2002.
Market forecasting newsletters 1983-1995 don’t forecast.
Others are less obvious and more sophisticated:
Hedge fund investors realized a dollar-weighted 2.9% over a 28-year period, trailing buy-and-hold by 3.2%
Endowments returned 3.8% from 2009 to 2016 trailing 60/40 by 5.5%
Overall, the average asset owner GAP from this “quick and dirty” meta-study is -3.1% per year.
Yes, there has been some criticism of how dollar-weighted returns are calculated, and it should be addressed. Nevertheless, investors are not surprised to see these results because their personal and anecdotal experience confirms them.
To me, the most surprising is the size of the Gap in total portfolios: 28,000 endowments lag 60/40 by 5.5% per year since 2009, and multi-asset mutual fund investors lag 60/40 by 6.8% per year since 1987. Are these results representative of the average asset owner’s total portfolio Gap?
Of course, the endowment Gap is not just a product of traditional short-term market-timing (here), but poor asset allocation decisions. However, asset allocation choices can be seen as just another form of trying to time the market over longer-horizons because just like short-term market timing, its main goal is still to avoid the drawdown risk.
Traditional investment professionals often struggle with IRR measure of return used in Private Equity industry. And while IRR’s do have their challenges, when properly modified, they could make traditional investors more accountable for the bad market timing decisions. Well-performing approaches and managers typically raise record assets at the peak of their performance, and then their performance deteriorates. IRR’s would capture this asymmetry and help guard investors against the common failures of asset allocation.
I wonder how large the Gap is for allocations to emerging markets, REITs, commodities, TIPs and MLP’s? And what about Risk Parity and Factor Investing?
Investors have become significantly more aware of the negative impact of high fees on their performance and hence the huge rise in passive investing and dropping fees. The cost of taxes has also been well understood producing various advances to mitigate it (tax loss harvesting, lower turnover, retirement and college saving plans, and variable life insurance solutions).
Yet today, I believe, the dollar vs. time weighted Gap still remains as the single largest unsolved ‘cost’ facing investors. (Ideas for solutions are welcomed in the comments).
