When Jack Bogle started the Vanguard 500 Index fund in 1975, I am sure that even he could not have foreseen how successful it would become in changing the way we invest. Not only have index funds become an increasing part of the landscape, but exchange traded funds have also added to the passive investing mix and index-based investing has expanded well beyond the S&P 500 to cover almost every traded asset market in the world. Today, you can put together a portfolio composed of index funds and ETFs to create any market exposure that you want in stocks, bonds or commodities. The growth of passive investing can be seen in the graph below, where I plot the proportion of the US equity market held by passive investors (in the form of ETFs and index funds) and active investors from 2005 to 2016:

To understand the shift to passive investing and why it has accelerated in recent years, we have to look no further than the investment reports that millions of investors get each year from their brokerage houses or financial advisors, chronicling the damage done to their portfolios during the course of the year by frenetic activity. Put bluntly, investors are more aware than ever before that they are often paying active money managers to lose money for them and that they now have the option to do something about this disservice.
Before you attack me for being a dyed-in-the-wool efficient marketer, there is a simple mathematical reason why this statement has to be true. During 2015, for instance, about 40% of institutional money in equities was invested in index funds and ETFs and about 60% in active investing of all types. The money invested in index funds and ETFs will track the index, with a very small percentage (about 0.11%) going to cover the minimal transactions costs. Thus, active money managers have to start off with the recognition that they collectively cannot beat the index and that their costs (transactions and management fees) will have to come out of the index returns. Not surprisingly, therefore, active investors will collectively generate less than the index during every period and more than half of them will usually underperform the index. To back up the first statement, here are the median returns for all actively managed funds, relative to passive index funds for various time periods ending in 2015:

The standard defense that most active investors would offer to the critique that they collectively underperform the market is that the collective includes a lot of sub-standard active investors. I have spent a lifetime talking to active investors who contend that the group (hedge funds, value investors, Buffett followers) that they belong to is not part of the collective and that it is the other, less enlightened groups that are responsible for the sorry state of active investing. In fact, they are quick to point to evidence often unearthed by academics looking at past data that stocks with specific characteristics (low PE, low Price to book, high dividend yield or price/earnings momentum) have beaten the market (by generating returns higher than what you would expect on a risk-adjusted basis). Even if you conclude that these findings are right, and they are debatable, you cannot use them to defend active investing, since you can create passive investing vehicles (index funds of just low PE stocks or PBV stocks) that will deliver those excess returns at minimal costs. The question then becomes whether active investing with any investment style beats a passive counterpart with the same style. SPIVA, S&P’s excellent data service for chronicling the successes and failures of active investing, looks at the excess returns and the percent of active investors who fail to beat the index, broken down by style sub-group.
The third and final line of defense for active investors is that while they collectively underperform and that underperformance stretches across sub-groups, there is a subset of consistent winners who have found the magic ingredient for investment success. That last hope is dashed, though, when you look at the numbers. If there is consistent performance, you should see continuity in performance, with highly ranked funds staying highly ranked and poor performers staying poor. To see if that is the case, I looked at how portfolio managers ranked by quartile in one period did in the following three years:
Note that the numbers in the table, when you look at all US equity funds, suggest very little continuity in the process. In fact, the only number that is different from 25% (albeit only marginally significant on a statistical basis) is that transition from the first to the fourth quartile, with a higher incidence of movement across these two quartiles than any other two. That should not be surprising since managers who adopt the riskiest strategies will spend their time bouncing between the top and the bottom quartiles.
As your final defense of active investing, you may roll out a few legendary names, with Warren Buffett, Peter Lynch and the latest superstar manager in the news leading the list, but recognize that this is more an admission of the weakness of your argument than of its strength. In fact, successful though these investors have been, it becomes impossible to separate how much of their success has come from their investment philosophies, the periods of time when they operated and perhaps even luck. Again, drawing on the data, here is what Morningstar reports on the returns generated by their top mutual fund performer each year in the subsequent two years:
Since it is no longer debatable that passive investing is winning the battle for investor money, and for good reasons, the question then becomes what the consequences will be. The immediate effects are predictable and painful for active money managers.
- The active investing business will shrink: The fees charged for active money management will continue to decline, as they try to hold on to their remaining customers, generally older and more set in their ways. Notwithstanding these fee cuts, active money managers will continue to lose market share to ETFs and index funds as it becomes easier and easier to trade these options. The business will collectively be less profitable and hire fewer people as analysts, portfolio managers and support staff. If the last few decades are any indication, there will be periods where active money management will look like it is mounting a comeback but those will be intermittent.
- More disruption is coming: In a post on disruption, I noted that the businesses that are most ripe for disruption are ones where the business is big (in terms of dollars spent), the value added is small relative to the costs of running the business and where everyone involved (businesses and customers) is unhappy with the status quo. That description fits the active money management like a glove and it should come as no surprise that the next wave of disruption is coming from fintech companies that see opportunity in almost every facet of active money management, from financial advisory services to trading to portfolio management.
- Corporate Governance: As ETFs and index funds increasing dominate the investment landscape, the question of who will bear the burden of corporate governance at companies has risen to the surface. After all, passive investors have no incentive to challenge incumbent management at individual companies nor the capacity to do so, given their vast number of holdings. As evidence, the critics of passive investors point to the fact that Vanguard and Blackrock vote with management more than 90% of the time. I would be more sympathetic to this argument if the big active mutual fund families had been shareholder advocates in the first place, but their track record of voting with management has historically been just as bad as that of the passive investors.
- Information Efficiency: To the extent that active investors collect and process information, trying to find market mistakes, they play a role in keeping prices informative. This is the point that was being made, perhaps not artfully, by the Bernstein piece on how passive investing is worse than Marxism and will lead us to serfdom. I wish that they had fully digested the Grossman and Stiglitz paper that they quote, because the paper plays out this process to its logical limit. In summary, it concludes that if everyone believes that markets are efficient and invests accordingly (in index funds), markets would cease to be efficient because no one would be collecting information. Depressing, right? But Grossman and Stiglitz also used the key word (Impossibility) in the title, since as they noted, the process is self-correcting. If passive investing does grow to the point where prices are not informationally efficient, the payoff to active investing will rise to attract more of it. Rather than the Bataan death march to an arid information-free market monopolized by passive investing, what I see is a market where active investing will ebb and flow over time.
- Product Markets: There are some who argue that the growth of passive investing is reducing product market competition, increasing prices for customers, and they give two reasons. The first is that passive investors steer their money to the largest market cap companies and as a consequence, these companies can only get bigger. The second is that when two or more large companies in a sector are owned mostly by the same passive investors (say Blackrock and Vanguard), it is suggested that they are more likely to collude to maximize the collective profits to the owners. As evidence, they point to studies of the banking and airline businesses, which seem to find a correlation between passive investing and higher prices for consumers. I am not persuaded or even convinced about either of these effects, since having a lot of passive investors does not seem to provide protection against the rapid meltdown of value that you still sometimes observe at large market cap companies and most management teams that I interact with are blissfully unaware of which institutional investors hold their shares.
Should you be an active investor or are you better off putting your money in index funds? The answer will depend on not only what you bring to the investment table in the resources but also on your personal make-up. I have long argued that there is no one investment philosophy that works for all investors but there is one that is just right for you, as an investor. In keeping with this philosophy of personalized investing, I think it behooves each of us, no matter how limited our investment experience, to try to address this question. To start this process, I will make the case for why I am an active investor, though I don’t think any you will or should care. I will begin by listing all the reasons that I will not give for investing actively. Since I use public information in financial statements and databases, my information is no better than anyone else’s. While my ego would like to push me towards believing that I can value companies better than others, that is a delusion that I gave up on a long time ago and it is one reason that I have always shared my valuation models with anyone who wants to use them. There is no secret ingredient or special sauce in them and anyone with a minimal modeling capacity, basic valuation knowledge and common sense can build similar models.
