“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 two-decade 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 two-decade investment into the stock back in 2001.

Start date: 04/19/2001
$10,000

04/19/2001
$18,453

04/16/2021
End date: 04/16/2021
Start price/share: $114.47
End price/share: $133.59
Starting shares: 87.36
Ending shares: 138.22
Dividends reinvested/share: $63.60
Total return: 84.65%
Average annual return: 3.11%
Starting investment: $10,000.00
Ending investment: $18,453.92

As shown above, the two-decade investment result worked out as follows, with an annualized rate of return of 3.11%. This would have turned a $10K investment made 20 years ago into $18,453.92 today (as of 04/16/2021). On a total return basis, that’s a result of 84.65% (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 $63.60/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 6.52/share, we calculate that IBM has a current yield of approximately 4.88%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 6.52 against the original $114.47/share purchase price. This works out to a yield on cost of 4.26%.
