With recent stock market turmoil, there have been plenty of renewed questions from nervous investors about the concept of investing risk. Are stocks really a good idea? Is the volatility worth it? Should I get out now while I still can?
Astute stock market bears point out that there have been many rolling periods where the inflation-adjusted stock market lost money for more than a decade. Recently, a 100% stock market investor starting in 2000 experienced 13 years of negative real returns before finally breaking even. Stocks absolutely do work out well in the long run, but if you’re not prepared to wait them out for at least a decade without questioning your plan and switching course, you may be in for a tough emotional ride. And remember, if you switch portfolios all the time you generally lose money.
Cooler heads are understandably fond of quoting the long term average returns of the stock market. Since the S&P500 averaged an 8.5% inflation-adjusted return since 1900, there are many years of history to prove that if you are patient and invest for the long run, it will all work out for the best. “High risk, high return” is a common mantra, meaning that the extra volatility carries a proportionally higher reward.
The idea that returns are linearly proportional to risk often leads to well-reasoned (but shaky, as I will explain) decisions about asset allocation. Would someone trade 1% a year for significantly more dependable returns? Judging by the popularity of hedge funds with expenses in that range that seems like a reasonable assumption, and retirees looking for consistency over maximum growth might find that particularly appealing. Would they trade 2-3% a year? Maybe not. That’s a lot of money to give up over time. So people study the averages and make the best decision they can.
But what if I told you that the risk adjusted return for stocks is a lot less than you might think?
