“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a decade-long holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Waste Management, Inc. (NYSE: WM)? Today, we examine the outcome of a decade-long investment into the stock back in 2009.

Start date: 12/07/2009
$10,000

12/07/2009
$44,803

12/05/2019
End date: 12/05/2019
Start price/share: $33.79
End price/share: $111.47
Starting shares: 295.95
Ending shares: 401.93
Dividends reinvested/share: $15.79
Total return: 348.03%
Average annual return: 16.18%
Starting investment: $10,000.00
Ending investment: $44,803.68

As we can see, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 16.18%. This would have turned a $10K investment made 10 years ago into $44,803.68 today (as of 12/05/2019). On a total return basis, that’s a result of 348.03% (something to think about: how might WM shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Waste Management, Inc. paid investors a total of $15.79/share in dividends over the 10 holding period, marking a second component of the total return beyond share price change alone. Much like watering a tree, reinvesting dividends can help an investment to grow over time — for the above calculations we assume dividend reinvestment (and for this exercise the closing price on ex-date is used for the reinvestment of a given dividend).

Based upon the most recent annualized dividend rate of 2.05/share, we calculate that WM has a current yield of approximately 1.84%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.05 against the original $33.79/share purchase price. This works out to a yield on cost of 5.45%.
