Years ago, it was easy to make money. Those who were around during the 1970s may even remember earning near 20%. A three-month CD in December 1980 earned over 18%, according to data from the Federal Reserve. Such rates are near 0.18% today — far below the core inflation rate (+1.3% year-over-year). At that rate, a $100 investment would grow to only $101.80 over ten years.

Evaporating Interest Rates

And don’t think buying longer-term bonds is the answer, either. Ten-year U.S. Treasury bonds now yield 0.7% compared to over 3% just two years ago. A $100 investment in a zero-coupon 10-year U.S. Treasury held for ten years would grow to only $105.75. Many are concluding that tying up $100 to earn $1.80 or $5.75 over TEN YEARS is not at all appealing. Look at the table below and see what $100 invested in cash or long-term Treasuries generated (above and beyond the initial principal) to during past decades. Creating gains was as easy as falling off a log. Just hold U.S. government-backed Treasury bills or bonds and let compounding do its thing.

These sorts of returns are not available today and have not been for some time now. Funds that used to find a home in the Treasury market are looking for return elsewhere. We can’t know with certainty what equity markets will return in the future, but it is possible to make a reasoned and educated guess. To do so, we could start with a dividend yield plus growth approach.

What About Stocks?

Chart A below starts with a U.S. economy growth estimate from the Congressional Budget Office (yellow area). To this estimate, we add the S&P 500 dividend yield (blue area). What we see is a declining and lower estimate of long-run, real stock returns. We don’t expect reality to match this expectation, but it makes for a reasonable starting point when estimating returns.

Chart A

Estimating Return: Dividend Plus Growth Approach

To round out the discussion, it is helpful to look at potential stock returns alongside bond returns. The graph below shows the real, inflation-adjusted yield on long-term U.S. Treasury Bonds (yellow line) alongside our real, inflation-adjusted S&P 500 estimated return from above (blue line). As you can see, the fall in interest rates, decline in dividend yield, and slower growth should lead to a moderation of portfolio returns.

What’s an Investor to Do?

Accepting returns the market has to offer, and adjusting lifestyle and expectations, is one viable option. In most respects a very simple and sensible one.

Yet, it is not beyond reason to look to do better. One way to do so is to adopt a tactical strategy to over-or-underweight asset classes in your portfolio. This approach is called Tactical Asset Allocation, or TAA. Such tactical management starts with a strategic portfolio that aligns with your overall goals. From that point, it may be possible to exploit the following to try to improve returns and/or mitigate risk:

  1. Identifying changes in market environment;
  2. Identifying valuation problems before others do; or
  3. Identifying trends within sub-asset classes.

Time to Think Active, Not Passive

It is important to note that such a program is an “overlay” that can compliment an existing financial plan. By our definition, TAA is not about swinging for the fences or timing when to get in or out of the market. What we are describing is an approach to making measured and disciplined tactical bets to try and exploit certain market inefficiencies with the aim of augmenting return and/or mitigating some risk.

We can do little about the starting point for interest rates and valuations. An ongoing and systematic program of tactical adjustments may make sense for an environment of low interest rates and potentially lower future stock returns. The 50% run-up since March has left many feeling elated, frustrated, and/or bewildered. During times like this, it is especially important to return to basics.

Markets often tell us explicitly what returns to expect and, more often, we are left to make reasonable estimates. Whether the estimates are made explicit or not doesn’t matter. Each investor in a 401(k), index fund, mutual fund, or stock and bond account is making assumptions about return each day. Some will act on assumptions and others will not.

A passive investing approach may have worked in the past, but we think the road ahead may prove frustrating. The time for taking a different and more tactical approach may now be upon us.
