Jonathan Clements wrote my favorite personal finance book of 2016 — How to Think About Money. People have an odd relationship with money because we spend most of our time stressed out about it. This book does a great job of trying to get people into the right frame of mind about their financial decisions and using money to make them happier, not miserable.
While discussing the need to embrace humility when investing, Clements brought up a fascinating story about an interview he did with the late-great Peter Bernstein in the mid-1990s. With a little help from the author himself I tracked down that original interview. Here’s the part that jumped out at me (taken from the original piece in the WSJ):
The bear market of 1973-74 nearly halved the Dow Jones Industrial Average, sending it spiraling down from a January 1973 peak of 1051.70 to 577.60 in December 1974. It was a slide that permanently changed the way people judged investment performance.
Before the fall, institutional and individual investors often didn’t bother to measure the returns their money managers produced against a benchmark index. Instead, they innocently turned over their money to bank trust departments and insurance companies, never doubting that they would get results that handily outpaced the Dow Jones Industrial Average.
What’s more, when performance comparisons were made in the 1950s and 1960s, they weren’t very meaningful. Money managers often looked just at the price change for the industrial average, says Peter Bernstein, an economic consultant and former money manager in New York. What about dividends, which historically have accounted for almost half of the market’s total return? They were ignored.
The 1973-74 bear market changed all that. Investors, burned by the plunge, vowed to keep closer tabs on their portfolio managers by comparing each manager’s performance with a benchmark. For many managers, the comparison didn’t prove flattering. That, in turn, prompted some investors to use investments that removed the manager from the decision making: index funds.
Before the bear market, ”managers were expected to regularly beat the market by 20%,” recalls Stephen Rogers, chairman of pension consultants Rogers, Casey & Associates in Darien, Conn. ”Most investors just relied on what their managers told them [about performance]. It was only with the 1973-74 [plunge] that things got torn apart.”
To recap, before the mid-1970s, investors:
- didn’t really know how to benchmark their investment performance correctly.
- ignored dividends when calculating performance comparisons.
- compared everything — even bonds — to the Dow Jones.
- really had no idea whether or not their money managers were any good or not.
Investment professionals spend a ton of time digging through historical market data to tease out the best strategies, trades or allocations (I’m no different). Yet very few ever try to place context around the state of the investment industry when performing backtests or scenario analysis.
There are so many facets to money management that are completely different now than they were in the past — trading costs, fund expenses, data availability, competition for outperformance, knowledge, the make-up of the investor base, investment offerings, research capabilities, technology, asset allocation preferences, demographics, geopolitical events, economic policies, access to advice and information and much more.
These things will be different in the future too.
Before the 1990s it was basically impossible for most investors to invest in small caps, emerging markets, commodities, many foreign markets or smart beta/factor-based funds.
There’s also a huge list of interest rate sensitive asset classes that didn’t really exist the last time we had a sustained rising rate environment — high yield bonds, private equity, unconstrained bond funds and REITs to name a few.
Some things in the the markets are never different (i.e., human nature) but many things are always different.
My point here is that it’s really difficult to understand historical market data without first considering a whole host of outside variables.
The entire Clements interview with Bernstein is worth a read:
