Another Look At The Total Return Roller Coaster
Note from dshort: I received a recent email requesting an update to my Total Return Roller Coaster series. I've now updated the charts below based on monthly data through the March close.
Here's an interesting set of charts that will especially resonate with those of us who follow economic and market cycles.
Imagine that five years ago you invested $10,000 in the S&P 500. How much would it be worth today, with dividends reinvested but adjusted for inflation?
The purchasing power of your investment has increased to $26,567 for an annualized real return of19.70%.
Had I posed the same question in March 2009, the answer would have been a depressing $5,521. The-5.93% real return would have cut the purchasing power of your initial investment nearly in half.
Fun Runs of the Roller Coaster
Let's increase the timeframe to 10 years. Strangely enough, the annualized return is slightly worse. Your $10K has grown to a little over $16K adjusted for inflation, an annualized real return of 4.87%.
The 15-year timeframe is quite disappointing. Your one-and-a-half decade investment of $10K has only grown to about 13.4K adjusted for inflation for a measly annualized real return of 1.94%.
If we extend our investment horizon to 20 years, the roller coaster is less volatile with higher lows and lower highs.
The volatility decreases further with a 30-year timeline. But even for that three-decade investment, the annualized returns since the 1901 have ranged from less than 2% to over 11%.
As these charts illustrate, and as many households have discovered during the 21st century so far, investing in equities carries substantial risk. Households approaching retirement should understand this risk and make rational decisions about diversification. In the past I've suggested that they should also consider fixed income alternatives for that part of the nest egg that will pay non-discretionary expenses not covered by Social Security and pensions. Unfortunately this traditional wisdom has been less helpful in recent years owing to the Fed Zero Interest Rate Policy (ZIRP) and various stimulus strategies, which have collectively shrunk interest rates.
