Best & Worst 10-Year Returns in Stock Market History (thru 2012)

10-Year Rolling Returns (Decade Returns)

This post graphs not only the best and worst decades in stock market history, but returns for all 10-year periods since around 1900; these are so-called 10-year rolling returns .

Stock Market Rolling 10-Year Returns Graph

Dow 10-Year Rolling Returns

Above is a graph of the 10-year total return of the DJIA (Dow Jones Industrial Average) beginning around 1900. (Note: Click on graph to expand it.) Each point on the graph represents the average annual return earned by a hypothetical investor who bought the Dow at that year-end and sold 10 years later, reinvesting dividends in the interim. For example, the first point on the graph shows that an investor who bought at year-end 1900, reinvested dividends annually, and sold at year-end 1910 earned 6.8% per year. Note that the returns prior to 1929 are estimated (which is why I sometimes omit them).

Stock Market Returns for a Decade are Cyclical, and Can be Negative

This is the same data as was used for the 10-year return histogram in the Stock Market Yearly Returns since 1929 post. However, this presentation gives us a significantly different impression. The histogram left us with the impression that 10-year returns have been consistently between 0% and 20%, and much less variable than yearly returns. That’s true. However, that presentation was incomplete because:

• It completely hides the cyclicality.
• It started in 1929 and missed the fact that 10-year returns can in fact be negative (a key reason why I started in 1901 for this post)
• It wasn’t as clear how often returns are almost zero

Note: This is another example of the boom and bust nature of the stock market alluded to in the discussion of the graph in 100 Years of Stock Market History .

The Best and Worst 10-Year Returns in Dow Jones History (since 1900)

So, what were the best & worst 10-year periods to own stocks? That is, in hindsight, when would have been the best and worst years to buy?

The best 10-year periods to own stocks were the years beginning in:

• 1918: the return was about 19.5% per year for the next 10 years
• 1948 & 49: 18.5% annual return
• 1987 & 88: about 18.5% annual return

The worst years to buy were:

• 1922: the return was 0.4% per year for the next 10 years
• 1928: -1.3% annual return — the only 10-year loss in my data; 1927 & 1929 were both just barely positive. All because of the 1929-1932 stock market crash .
• 1964: annual return of 0.3%

Note: FYI, the decades ending in 2008 and 2009 didn’t make the above list, but they’re next. The decade ending in 2009 is 6th at 1.3%; 2008 is 7th at 1.7%. For the most recent 10 years, ending 2012, the return was 7.2%.

Average Returns for a Decade, and the Impact of Inflation & Expenses

On average, stock market returns for a decade were around 10% per year. However, the 10-year returns varied considerably, depending on your start year.

The graph shows several instances of near-zero 10-year returns. To my way of thinking, a decade is a long time to go with essentially no return on your investment. In addition, there were a number of 10-year periods with returns of 5% or less. Remember, these returns have not been adjusted for inflation. If you assume that over this period inflation has averaged about 3% per year, then the less than 5% nominal returns become less than 2% in real terms, and the near-zero returns become negative. (For a more detailed discussion of nominal vs real rates of return, see this post .)

A Better Way to Look at Stock Market Returns — Especially for Retirement Planning

The graph above should make it clear that investors don’t always get average returns! Sometimes returns are above average; sometimes returns are below average. What if the market returns only 5 or 6% in the next 10 years instead of 10%? What are the chances of that? What impact would that have on your retirement portfolio?
