“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: 11/29/1999
$10,000

11/29/1999
$19,332

11/26/2019
End date: 11/26/2019
Start price/share: $104.19
End price/share: $135.09
Starting shares: 95.98
Ending shares: 143.25
Dividends reinvested/share: $56.10
Total return: 93.51%
Average annual return: 3.35%
Starting investment: $10,000.00
Ending investment: $19,332.50

As we can see, the twenty year investment result worked out as follows, with an annualized rate of return of 3.35%. This would have turned a $10K investment made 20 years ago into $19,332.50 today (as of 11/26/2019). On a total return basis, that’s a result of 93.51% (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.]

Beyond share price change, another component of IBM’s total return these past 20 years has been the payment by International Business Machines Corp of $56.10/share in dividends to shareholders. Automatic reinvestment of dividends can be a wonderful way to compound returns, and for the above calculations we presume that dividends are reinvested into additional shares of stock. (For the purpose of these calcuations, the closing price on ex-date is used).

Based upon the most recent annualized dividend rate of 6.48/share, we calculate that IBM has a current yield of approximately 4.80%. 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 $104.19/share purchase price. This works out to a yield on cost of 4.61%.

One more investment quote to leave you with:
“Investors should always keep in mind that the most important metric is not the returns achieved but the returns weighed against the risks incurred. Ultimately, nothing should be more important to investors than the ability to sleep soundly at night.” — Seth Klarman
