“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 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 Schlumberger Ltd (NYSE: SLB)? Today, we examine the outcome of a two-decade investment into the stock back in 1999.

Start date: 04/15/1999
$10,000

04/15/1999
$23,215

04/12/2019
End date: 04/12/2019
Start price/share: $30.50
End price/share: $45.65
Starting shares: 327.87
Ending shares: 508.85
Dividends reinvested/share: $23.05
Total return: 132.29%
Average annual return: 4.30%
Starting investment: $10,000.00
Ending investment: $23,215.94

The above analysis shows the two-decade investment result worked out as follows, with an annualized rate of return of 4.30%. This would have turned a $10K investment made 20 years ago into $23,215.94 today (as of 04/12/2019). On a total return basis, that’s a result of 132.29% (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 $23.05/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 2/share, we calculate that SLB has a current yield of approximately 4.38%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2 against the original $30.50/share purchase price. This works out to a yield on cost of 14.36%.
