As a follow-up to Vanguard founder Jack Bogle’s 2015 stock market prediction paper and related Morningstar article, here are a few selected slides from the presentation deck by Jack Bogle at the Bogleheads XIV conference in October 2015.

The formula for predicting future stock market returns is:

Future stock returns = Current dividend yield + Predicted earnings growth ± (Reversion to long-term average P/E ratio)

The formula for predicting future bond market returns is:

Future bond returns = Current yield to maturity

At 6% nominal for stocks and 3% nominal for bonds, both 10-year numbers are below long-term averages. However, the 10-year breakeven inflation rate based on TIPS and Treasury yields is roughly 1.5% as of now (late 2015). Using those inflation numbers would result in 4.5% real returns for stocks and 1.5% real returns for bonds, a brighter picture than that painted by other forecasts.

Admittedly it is not a large sample size, but here is a plot of how the 10-year predictions have done so far (1990-2014):

As noted previously, I like to keep track of these forecasts along with those provided by:

  1. Good article. The last chart seems off though. When comparing actual to estimated returns shouldn’t the scale be the same for both? I think if the scale were the same, the estimated returns would show more divergence from actual returns.

  2. High risk / Low return / No place is safe.

    Though I calculated that if the brilliant Iraq and Afghanistan illegal invasions never occurred and that money was divided up and distributed to tax payers who actually pay taxes it would have probably resulted in a check for about $35,000 per tax payer. Which would almost cover the cost to the non-criminal elite for living with zero percent interest rates for 8 years.

    Jonathan,
    Great article, I never invest in Bonds because they bring small interest rates. When I want to play on safe I invest in funds they are much better solution for safe investing, with higher numbers then bonds. I would rather be bit risky player, with average interest of 7% then safe player with interest of 3%.

    • I am not sure what you mean by saying “When I want to play on safe I invest in funds”. What do you mean by funds? It doesn’t make any sense.

  4. Could you please share where are you allocating funds? Vti/bond?
