“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— 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 Schlumberger Ltd (NYSE: SLB)? Today, we examine the outcome of a twenty year investment into the stock back in 2002.

Start date: 03/11/2002
$10,000

03/11/2002
$22,687

03/08/2022
End date: 03/08/2022
Start price/share: $29.37
End price/share: $45.08
Starting shares: 340.48
Ending shares: 503.10
Dividends reinvested/share: $21.63
Total return: 126.80%
Average annual return: 4.18%
Starting investment: $10,000.00
Ending investment: $22,687.39

As shown above, the twenty year investment result worked out as follows, with an annualized rate of return of 4.18%. This would have turned a $10K investment made 20 years ago into $22,687.39 today (as of 03/08/2022). On a total return basis, that’s a result of 126.80% (something to think about: how might SLB shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Schlumberger Ltd paid investors a total of $21.63/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 .5/share, we calculate that SLB has a current yield of approximately 1.11%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .5 against the original $29.37/share purchase price. This works out to a yield on cost of 3.78%.
