Estimating Future Stock Returns – Update


I’d say this is getting boring, but it’s pretty fascinating watching the rally run.  Now, this is the seventh time I have done this quarterly analysis.  The first one was for December 2015.  Over that time period, the expected annualized 10-year return went like this, quarter by quarter: 6.10%, 6.74%, 6.30%, 6.01%, 5.02%, 4.79%, and 4.30%.  At the end of June 2017, the figure would have been 4.58%, but the rally since the end of the quarter shaves future returns down to 4.30%.


Jim O’Shaughnessy: Revisting The Ideas Buried In The Graveyard

Yeah, for the the research graveyard, do you ever Read More

We are now in the 93rd percentile of valuations.


This era will ultimately be remembered as a hot time in the markets, much like 1965-9, 1972, and 1997-2001.

The Internal Logic of this Model

I promised on of my readers that I would provide the equation for this model.  Here it is:

10-year annualized total return = 32.77% – (70.11% * Percentage of total assets held in stocks for the US as a whole)

Now, the logic of this formula stems from the idea that the return on total assets varies linearly with the height of the stock market, and the return on debt (everything else aside from stocks) does not.  After that, the formula is derived from the same formula that we use for the weighted average cost of capital [WACC].  Under those conditions, the total returns of the stock market can be approximated by a linear function of the weight the stocks have in the WACC formula.

Anyway, that’s one way to think of the logic behind this.

The Future?

Now, what are some of the possibilities for the future?

Above you see the nineteen scenarios for where the S&P 500 will be in 10 years, assuming a 2% dividend yield, and looking at the total returns that happen when the model forecasts returns between 3.30% and 5.30%.  The total returns vary from 2.31%/year to 6.50%, and average out to 3.97% total returns.  The bold line above is the 4.30% estimate.

As I have said before, this bodes ill for all collective security schemes that rely on the returns of risky assets to power the payments.  There is no conventional way to achieve returns higher than 5%/year for the next ten years, unless you go for value and foreign markets (maybe both!).

Then again, the simple solution is just to lighten up and let cash build.  Now if we all did that, we couldn’t.  Who would be buying?  But if enough of us did it such that equity valuations declined, there could be a more orderly market retreat.

The attitude of the market on a qualitative basis doesn’t seem nuts to me yet, so I am at maximum cash for ordinary conditions, but I haven’t hedged.  When expected 10-year market returns get to 3%/year, I will likely do that, but for now I hold my stocks.

David J. Merkel, CFA, FSA — 2010-present, I am working on setting up my own equity asset management shop, tentatively called Aleph Investments. It is possible that I might do a joint venture with someone else if we can do more together than separately. From 2008-2010, I was the Chief Economist and Director of Research of Finacorp Securities. I did a many things for Finacorp, mainly research and analysis on a wide variety of fixed income and equity securities, and trading strategies. Until 2007, I was a senior investment analyst at Hovde Capital, responsible for analysis and valuation of investment opportunities for the FIP funds, particularly of companies in the insurance industry. I also managed the internal profit sharing and charitable endowment monies of the firm. From 2003-2007, I was a leading commentator at the investment website Back in 2003, after several years of correspondence, James Cramer invited me to write for the site, and I wrote for RealMoney on equity and bond portfolio management, macroeconomics, derivatives, quantitative strategies, insurance issues, corporate governance, etc. My specialty is looking at the interlinkages in the markets in order to understand individual markets better. I no longer contribute to RealMoney; I scaled it back because my work duties have gotten larger, and I began this blog to develop a distinct voice with a wider distribution. After three-plus year of operation, I believe I have achieved that. Prior to joining Hovde in 2003, I managed corporate bonds for Dwight Asset Management. In 1998, I joined the Mount Washington Investment Group as the Mortgage Bond and Asset Liability manager after working with Provident Mutual, AIG and Pacific Standard Life. My background as a life actuary has given me a different perspective on investing. How do you earn money without taking undue risk? How do you convey ideas about investing while showing a proper level of uncertainty on the likelihood of success? How do the various markets fit together, telling us us a broader story than any single piece? These are the themes that I will deal with in this blog. I hold bachelor’s and master’s degrees from Johns Hopkins University. In my spare time, I take care of our eight children with my wonderful wife Ruth.
