US businessman, investor and philanthropist David Booth, founded global asset management firm, Dimensional Fund Advisors, 40 years ago. Here, he has brought together five timeless lessons from his decades in the finance industry.
Gambling is a short-term bet. If you treat the market like a casino, and you’re picking stocks or timing the market, you need to be right twice - in an aim to buy low and sell high. Professor Fama showed that it’s unlikely for any individual to be able to pick the right stock at the right time, especially more than once.
Investing, on the other hand, is long term. While all investments have risk, there are things you can do as a long-term investor to manage those risks and be prepared. As Nobel laureate Merton Miller said, “diversification is your buddy.” Investing is buying a little bit of almost every company and holding them for a long time. The only bet you’re making is on human ingenuity to find productive solutions to the world’s problems.
Over the past 100 years, the US stock market, as measured by the S&P 500, has returned a little over 10% on average per year but hardly ever close to 10% in any given year. The same is true of dozens of other markets around the world that have delivered strong long-term average returns.
Stock market behaviour is uncertain, just like most things in our lives. None of us can make uncertainty disappear but dealing thoughtfully with uncertainty can make a huge difference in our investment returns, and even more importantly, our quality of life.
The way to deal with uncertainty is to prepare for it. Without uncertainty, there would be no opportunity to do better than a relatively riskless return like that from a money market fund. We always emphasise that risk and expected returns are related, which means you can’t have more of one without more of the other. Make the best-informed choices you can, then monitor performance and make portfolio adjustments as necessary.
Come up with a plan to get back on track in case things don’t go as expected. Remember, you can’t control markets, so don’t blame yourself for results outside your control. Try to relax knowing you’ve made the best-informed choices you can. A trusted financial adviser, a fiduciary who puts your interests first can help you cultivate this sort of discipline and long-term perspective.
I was compelled to approach investing differently by the research Fama and other leading academics were doing to better understand markets and returns. There’s general agreement on what financial science tells us, yet so much can be gained or lost in application. Just as some sports teams can consistently execute their strategies better than others, investment professionals can consistently add value by dealing better with market mechanics.
Bob Merton and Myron Scholes were recognised as Nobel laureates for their options-pricing model, which shows that flexibility has value. Great implementation requires paying attention to detail, applying judgment, and being flexible.
If an investment sounds too good to be true, it probably is. When people ask me if I’m investing in the latest shiny investment idea, I tell them, “If I don’t understand something, I don’t invest in it.” That’s because I’ve seen a lot of fads come and go.
TV pundits handing out stock tips? Friends letting friends in on their next big investment? I see these more as entertainment than information.
Stress is induced when people think that they can time markets or find the next winning stock, or that they can hire people who can. There is no compelling evidence that professional stock pickers can consistently beat the markets. Even after one outperforms, it’s difficult to determine whether a manager was skillful or lucky.
The good news is you can still do well without having to find what markets might have missed. While markets are unpredictable and may even seem chaotic at times, they have an underlying order. Buyers and sellers come together and trade, which is the activity that sets market prices. Unless each side agrees to a price, they don’t trade.
New information and expectations about returns are quickly incorporated. Consistently finding big winners is difficult, but everybody can have access to the expected returns that a diversified, low-cost portfolio can generate.
It can be difficult to stay on the investment course during periods of extreme market volatility. At the end of March 2020, the S&P 500 was down nearly 20% for the year. Record amounts of money exited from equity mutual funds and went into money market accounts. Those investors who stayed out of the equity market missed out on the subsequent 56% gain in the S&P 500 over the next 12 months. We will all remember 2020 for the rest of our lives. It serves as an example of how important it is to maintain discipline and stick to your plan.
By learning to embrace uncertainty, you can also focus more on controlling what you can control. You can make an impact on how much you earn, how much you spend, how much you save, and how much risk you take. This is where a professional you trust can really help. Discipline applied over a lifetime can have a powerful impact.
