How good are Vanguard’s active funds?



Investors, and indeed financial professionals and commentators, are often confused by the fact that Vanguard provides actively managed funds. I must admit, as one of Vanguard’s biggest fans, that it slightly puzzles me too.

Vanguard is, of course, virtually synonymous with passive investing. It was Vanguard’s founder, Jack Bogle, who launched the first index fund for retail investors in the mid-1970s, and who has since became the most vociferous critic of active management.

Yet not only does Vanguard offer active funds, it also (at least here in the UK) enthusiastically promotes them. It’s not about active and passive, Vanguard’s marketing message goes; it’s all about cost.

To a large extent, that’s true. As research by Morningstar and others has consistently shown, cost is the single most accurate predictor of future fund returns. Certainly, Vanguard’s active fund fees are generally considerably lower than those of its rivals.

But, given the choice of an active Vanguard fund and a passive one, which should you go for? The investment author Andrew Hallam conducted research into this question in March 2015. He looked at the performance of Vanguard’s equity and bond funds, across seven different categories, over the previous ten years.

In some categories, Hallam found, the active funds produced the higher returns (particular in international equities). But, overall, Vanguard’s index funds beat the active funds by 0.71% per year. 

Now, 71 basis points might not sound like a great deal, but when that figure is compounded over several decades, it can add up to a substantial amount.

Someone else who has looked at this issue closely is the financial adviser and author Mark Hebner. In June 2016 Hebner analysed the performance of all 60 of Vanguard’s US-based active funds which had a track record of at least ten years.

The fees, he confirmed, were substantially lower than the industry average. Vanguard charged an average of 0.36% for its equity funds and 0.21% for its bond funds.

Hebner then looked at turnover ratios. The average was 40% for equity funds and 90% for bond funds; in other words, a typical holding period was between one and two-and-a-half years. These figures are much more in line with the industry average and imply that Vanguard’s active managers tend to make decisions based on short-term outlooks. Although transaction costs aren’t included in the headline fee, they are borne by the investor and have a significant on net returns.

The next question Hebner addressed was whether Vanguard investors could expect superior performance in return for the premium they were paying for active management. This is what he found:

  • 30 funds (50% of the total), since inception, had outperformed their benchmark index, i.e. delivered POSITIVE alpha, or returns over and above the index;
  • 30 funds (again, 50% of the total), since inception, had underperformed their benchmark index, or delivered NEGATIVE alpha; and
  • two funds (3.3% of the total) had outperformed their benchmarks with sufficient consistency to provide 95% confidence that such outperformance would persist as opposed to being based on random outcomes.

This distinction between repeatable skill and random chance is very important. By random chance alone, you would expect either one or two of the funds analysed (1 in 40 to be precise) to produce what’s called statistically significant alpha. Put another way, no more of Vanguard’s funds outperformed than you would expect just from random chance.

“In general,” Hebner concluded, “Vanguard has not demonstrated that their process of hiring the best analysts and managers and implementing their investment strategies is superior to anyone else. To say they apply a unique process to just two of their investment strategies seems very unlikely.”

So, then, are Vanguard’s low-cost active funds a good bet? They are, as with all active funds, most definitely a bet. But a good one? Well, because the fees are lower, using an active fund from Vanguard is a better bet than choosing a typical average fund.

But the bottom line is that markets are pretty darned efficient. All active management, low-fee or otherwise, is a zero-sum game before costs and a negative-sum game after costs. Not even Vanguard, for all the good that it’s done for investing and for investors, can escape those brutal facts.

Do Vanguard’s active managers possess skill and insight or have resources at their disposal that active managers that all the other big fund houses don’t? The figures don’t lie, and the figures suggest they don’t.
