“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 Schlumberger Ltd (NYSE: SLB)? Today, we examine the outcome of a two-decade investment into the stock back in 2004.

Start date: 03/22/2004
$10,000

03/22/2004
  $25,943

03/21/2024
End date: 03/21/2024
Start price/share: $31.18
End price/share: $54.44
Starting shares: 320.72
Ending shares: 476.37
Dividends reinvested/share: $22.67
Total return: 159.33%
Average annual return: 4.88%
Starting investment: $10,000.00
Ending investment: $25,943.21

As shown above, the two-decade investment result worked out as follows, with an annualized rate of return of 4.88%. This would have turned a $10K investment made 20 years ago into $25,943.21 today (as of 03/21/2024). On a total return basis, that’s a result of 159.33% (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 $22.67/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 1.1/share, we calculate that SLB has a current yield of approximately 2.02%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.1 against the original $31.18/share purchase price. This works out to a yield on cost of 6.48%.

One more piece of investment wisdom to leave you with:
