Remembering the Wisdom of ‘St.’ Jack Bogle

The Vanguard founder’s three timeless pillars of investing

Timothy J. Keating //February 7, 2019//

John Clifton Bogle, Jr., the Vanguard founder who brought low-cost index funds to the masses, died earlier this month at the age of 89. His critics snidely referred to him as “St. Jack” because they felt his critiques of the mutual fund industry specifically, and Wall Street generally, were often sanctimonious.

If the label of sanctimony is the cross that Bogle had to bear for his conversion to the gospel of low costs, count us among his disciples. One Wall Street Journal columnist elegantly summed up Bogle’s lifetime achievement as “lowering the costs of investing almost to the vanishing point.”

By now, the Vanguard story is well-known. Believing it was foolish to pay high fees to fund managers trying to outperform the market — since so few actually do — Bogle created the first equity index mutual fund in 1976. The rest is history. At about $5 trillion in assets under management, the Vanguard Group is now the world’s second largest asset manager, and index funds now represent nearly 50 percent of all mutual fund assets.

Bogle wrote 13 books devoted to elucidating some basic principles he felt investors should follow: saving regularly, buying and holding investments rather than trying to time the market, diversifying those investments and staying the course. He also gave us more than a few priceless quotes reflecting fundamental truths, including this gem: “In the fund business, you get what you don’t pay for.” In other words, every dollar not paid to a fund manager or for administrative expenses means an extra dollar of return for investors.

The Wall Street Journal editorial board elevated Bogle to the same pantheon of business titans as Henry Ford, Sam Walton and Michael Dell for his role in driving down prices for the benefit of the masses. And in Berkshire Hathaway’s 2016 annual report, Warren Buffet said "If a statue is ever erected to honor the person who has done the most for American investors, the hands-down choice should be Jack Bogle." 

For the first few decades of Bogle’s crusade, the principal argument against indexing was that it amounted to a guarantee of “average” — and therefore mediocre — results. But as the years passed and the data rolled in, it became clear that active managers were systematically, over every time period, underperforming index returns.

Nobel laureate William Sharpe revealed the reason. “Because active and passive returns are equal before cost, and because active managers bear greater costs, it follows that the after-cost return from active management must be lower than that from passive management.”

In fact, based on the now indisputable evidence, index funds actually give the investor top-decile returns.  Better than average is a mathematical certainty, but the best performance is surprising. 

We have recognized Bogle’s enormous influence in past articles, in particular, with respect to a simple, reliable model he developed for forecasting 10-year stock and bond returns and on the index fund’s 40th anniversary in 2016.

To be sure, we profoundly disagree with two of Bogle’s long-held positions on asset allocation and the benefits of international equities. But although Bogle believed in a 60 percent stocks/40 percent bonds asset allocation model and that American investors need not hold any foreign equities, these differences amount to mere quibbles over policy.

Even more important than the gift of lower costs and arguably the greatest part of Bogle’s legacy are some of the fundamental truths and timeless principles that shaped his worldview and formed the foundational pillars of the overall investment wisdom he imparted.  Here, we share three:

  1. Long-Term Thinking

There are only so many ways to explain the pitfalls of short-term thinking and the benefits of a long-term perspective.  Here’s one you aren’t likely to forget:

If you never peek from the age of 20 to the age of 70, you’ll rip that first 401(k) statement open at age 70, and I recommend you have a doctor on hand because you’ll go into a dead faint. Your heart might even stop. You’re going to have an amount of money you can’t even imagine.

Takeaway:  Think in decades, not days.


  1. Behavior

Benjamin Graham famously said, “The investor’s chief problem — and even his worst enemy — is likely to be himself.” Similarly, Nobel Prize-winning behavioral economist Daniel Kahneman advised, “All of us would be better investors if we just made fewer decisions.” Here is Bogle’s more memorable spin on the same subject:

While the interests of Wall Street’s businesses are well served by an aphorism “Don’t just stand there — do something!” The interests of Main Street’s investors are well served by an approach that is its diametrical opposite: “Don’t do something — just stand there!”

Takeaway:  Investor behavior — not investment performance — drives the financial outcomes experienced by most investors.


  1. Simplicity

Sir William of Ockham was a 14th century English Franciscan friar and scholastic philosopher whose “razor,” or law of parsimony, postulated that the simplest solution to a problem is the solution most likely to be correct, and that problems should not be more complicated than necessary. Bogle loved Occam’s razor and referenced it often:

Avoid complexity and rely on simplicity and parsimony and your investments should flourish.

Takeaway: Amen. Thank you, ‘St.’ Jack Bogle, for helping to crush the crisis of complexity and making the investment world a simpler place for those choosing to abide by this everlasting wisdom.
