“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a twenty year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into International Business Machines Corp (NYSE: IBM)? Today, we examine the outcome of a twenty year investment into the stock back in 1999.

Start date: 07/12/1999
$10,000

07/12/1999
$14,891

07/10/2019
End date: 07/10/2019
Start price/share: $137.81
End price/share: $140.47
Starting shares: 72.56
Ending shares: 106.05
Dividends reinvested/share: $53.10
Total return: 48.97%
Average annual return: 2.01%
Starting investment: $10,000.00
Ending investment: $14,891.07

As shown above, the twenty year investment result worked out as follows, with an annualized rate of return of 2.01%. This would have turned a $10K investment made 20 years ago into $14,891.07 today (as of 07/10/2019). On a total return basis, that’s a result of 48.97% (something to think about: how might IBM shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that International Business Machines Corp paid investors a total of $53.10/share in dividends over the 20 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 6.48/share, we calculate that IBM has a current yield of approximately 4.61%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 6.48 against the original $137.81/share purchase price. This works out to a yield on cost of 3.35%.
