Extending time horizons is critical to building wealth

by Richard Bernstein, Richard Bernstein Advisors

The basic tenets of building wealth, like having a well-diversified portfolio with long time horizons, are not difficult concepts that are relatively easy to implement. So, why don’t people follow them?

Throughout financial history there have always been Siren songs of “get rich quick” investments tempting investors to ignore their long-term financial plans for immediate gratification, and rush to newer, better, more exciting investments that promise to quickly build wealth. Unfortunately, these ideas end up destroying wealth rather than building it.

Individual investors today seem to be again straying from proven wealth-building strategies and have become significant risk-takers. The beta of individual investors’ portfolios is near a record high of 1.20 suggesting they are punting prudent diversified portfolios to trade individual stocks (See Chart 1 courtesy of BofA Global Investment Strategy).

Different ways to look at risk/return

Within today’s more speculative backdrop, we thought it appropriate to revisit some of the basic risk/return charts that we started producing more than 20 years ago. The charts below show two different definitions of risk and several different time horizons.

Traditional risk/return analyses incorporate one-year time horizons, but we also look at time horizons based on 3-, 5-, and 10-year holding periods. We use a classic measure of risk, standard deviation, but we also show analyses incorporating the probability of losing money as a risk measure. We’ve long thought investors don’t care as much about volatility as they do about losing money or falling short of a required return.

There are several results that investors tend to find surprising:

1. Risk diminishes as time horizons lengthen.

“Risk” diminishes as time horizons lengthen. In the charts that incorporate the probability of a loss as the measure of risk, lengthening time horizon significantly decreases risk and increasingly makes asset selection purely a function of anticipated return. In other words, lengthening time horizon is one of the easier risk reduction tools.

In the charts that depict risk as the probability of a negative return, note that the asset classes gravitate “west” as the charts move from 12-month to 10-year time periods. Over long time periods, the probability of losing money generally goes down. (This is not true for all asset classes as we discuss below.)

2. Low quality outperforms high quality over the long-term.

Contrary to popular belief, low quality stocks outperform high quality stocks over longer time periods. This really shouldn’t be surprising because it’s the same effect supporting high yield/junk bonds outperforming Treasuries or other high-quality bonds through time.

We define quality using S&P Common Stock Rankings, which are based on the stability and the growth in earnings and dividends over a 10-year period. Because we have been using this measure for nearly 30 years, there is considerable out-of-sample testing to support our contention.

Low quality stocks’ outperformance comes with significant volatility versus high quality stocks, but it does not come with a substantially higher probability of losing money over longer time horizons. That suggests true long-term investors should focus on lower quality stocks.

There has been considerable behavioral finance research on why this is true. That research can be summed up with the statement, “bad companies make very good stocks over the long term.”

3. Small stocks aren’t quite so risky.

It seems intuitive that smaller companies should be riskier than larger companies, but that might not be the case. Other than when analyzing 12-month holding periods, the Russell 2000 had lower volatility and a lower probability of losing money than did the S&P 500®.

Investors today are very focused on “large cap high quality” companies. However, they might be better off with smaller, lower quality stocks if their time horizons are longer than a year.

4. Date cash, but never marry it.

One way the Federal Reserve injects monetary policy into the economy is by increasing or decreasing the relative attractiveness of cash. When the Fed raises short-term interest rates to slow the economy, they explicitly do so to make cash incrementally attractive relative to other asset classes. That attractiveness disintermediates other investments and generally raises the cost of capital in the economy which slows overall economic activity.

Although cash might be currently attractive because of the Fed tightening monetary policy and raising short-term interest rates, cash is a terrible asset class to hold for longer time periods. It ranks as the lowest returning asset class for every time horizon studied. Although investing in cash might be opportunistic from time to time, particularly during periods of secular or rising inflation, the unattractiveness of cash grows exponentially as one extends time horizon. Only Japanese equities and Commodities were inferior investments relative to cash over 10-year time periods, and every other asset class was superior to cash when defining risk as the probability of a loss. So, investors might date cash every now and then, but they probably shouldn’t marry it.

5. Japan and commodities have clearly been hurt by secular disinflation. Could that change?

The two asset classes hurt the most by secular disinflation were Japanese equities and Commodities. These were the two least rewarding asset classes regardless of the time horizon studied, or the definition of risk used. To a lesser extent, small stocks have also been constrained by secular disinflation.

However, we’ve suggested that secular disinflation might be ending if globalization continues to contract. If that turns out to be true, then these asset classes might become more attractive as the global economy shifts from secular disinflation to secular inflation, as we think it might. In addition, most investors are significantly underweighting these asset classes.

Stick with the plan and ignore fear…and greed.

Today’s stock markets are highly speculative and individual investors are more active participants taking more risk than at any time since the Global Financial Crisis. Their enthusiasm should not lead them away from following their previously formulated financial plans.

Financial plans are blueprints for building wealth by reinforcing the building blocks of wealth: diversification and longer time horizons. One might change the paint color on a house, but one should be very thoughtful before making changes to the foundation or structure of the home.

It’s the same with investment portfolios. The next 10 minutes might be exciting, but such a short-term approach could lead to missed opportunities if one doesn’t pay more attention to the next 10 years.

INDEX DESCRIPTIONS:

The following descriptions, while believed to be accurate, are in some cases abbreviated versions of more detailed or comprehensive definitions available from the sponsors or originators of the respective indices. Anyone interested in such further details is free to consult each such sponsor’s or originator’s website.

The past performance of an index is not a guarantee of future results.

Each index reflects an unmanaged universe of securities without any deduction for advisory fees or other expenses that would reduce actual returns, as well as the reinvestment of all income and dividends. An actual investment in the securities included in the index would require an investor to incur transaction costs, which would lower the performance results. Indices are not actively managed, and investors cannot invest directly in the indices.
