We’ve all been there, done that: When the markets grow volatile, they can literally make your stomach churn. As a team member of Hill Investment Group, I know better than to get too hung up on the never-ending breaking news in the popular financial press, but I do still find it helpful to read the perspectives of other thought leaders who are as committed as we are to evidence-based investing.

Here are two such pieces published during the recent jolts of market volatility. I found them helpful; I hope you do too:

“When Investing in Stocks Makes You Feel Like Throwing Up and You Do It Anyway,” by Jason Zweig of The Wall Street Journal

Zweig reflects on how awful it felt to stay invested during the Great Recession, but how glad he is now that he overcame his deepest doubts: “A happy few investors, among them Warren Buffett, his business partner Charles Munger and their mentor Benjamin Graham, may have long-term thinking built into them by nature. The rest of us have to cultivate it by nurture.”

“Some alternatives to Evidence-Based Investing,” by Josh Brown, the Reformed Broker

Satire can be a great healer. Here, Brown lists some of the “better” tactics people use instead of evidence-based investing and concludes: “The harvestable errors of emotionally unaware people in the marketplace are a bumper crop for the patient, the sane and the disciplined.” Tough but true love about the wisdom of evidence-based investing.

Who invented the index fund? Most investors would guess it was Vanguard founder John Bogle. Bogle did launch the first publicly available index fund in 1976. After being derided as “Bogle’s folly,” it went on to become today’s Vanguard 500 Index Fund, a name nearly synonymous with indexing.

So it may come as a surprise to learn that Bogle did not actually invent the index fund. That credit goes to three gentlemen who created the first institutional index funds in the early 1970s: Dimensional Fund Advisor board member John “Mac” McQuown, co-founder and Executive Chairman David Booth, and co-founder Rex Sinquefield.

In this brief video, Booth reflects on the evolution of indexing and evidence-based investing, which led to Dimensional’s own value-added approach. “The basic idea of indexing has been an overwhelming success,” says Booth, but “Dimensional built the firm on the idea that we could do better.”

Warren Buffett has now been in the business of running Berkshire Hathaway for 53 years, and counting. In his newly released 2017 letter to shareholders, he reminds us why his name has grown over those years to be nearly synonymous with sound business practice here in America and as a master communicator of the money world.

As usual, his latest letter is filled with advice worth heeding. First, as we previewed in December 2017, Buffett shared the final results of the 10-year bet he placed against hedge funds. He won so dramatically that his opponent threw in the towel last May, before the decade was even through. Reflecting on his win, Buffett wrote (emphasis ours):

The bet illuminated another important investment lesson: Though markets are generally rational, they occasionally do crazy things. Seizing the opportunities then offered does not require great intelligence, a degree in economics or a familiarity with Wall Street jargon such as alpha and beta. What investors then need instead is an ability to both disregard mob fears or enthusiasms and to focus on a few simple fundamentals. A willingness to look unimaginative for a sustained period – or even to look foolish – is also essential.

The wager was all the more telling, in that Buffett often bills himself as a person who avoids unnecessary risks. In this year’s letter, for example, he reiterated:

Our aversion to leverage has dampened our returns over the years. But Charlie and I sleep well. Both of us believe it is insane to risk what you have and need in order to obtain what you don’t need. We held this view 50 years ago when we each ran an investment partnership, funded by a few friends and relatives who trusted us. We also hold it today after a million or so ‘partners’ have joined us at Berkshire.

Exactly. This is our perspective at HIG as well. Take care of your clients above all else. Help people focus on their own goals and the financial fundamentals – regardless of what’s hot and what’s not in trending techniques. Excel at these essentials, and the rest will likely take care of itself.
