“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 2004.

Start date: 01/29/2004


End date: 01/26/2024
Start price/share: $30.91
End price/share: $52.92
Starting shares: 323.52
Ending shares: 479.21
Dividends reinvested/share: $22.49
Total return: 153.60%
Average annual return: 4.76%
Starting investment: $10,000.00
Ending investment: $25,352.48

As we can see, the two-decade investment result worked out as follows, with an annualized rate of return of 4.76%. This would have turned a $10K investment made 20 years ago into $25,352.48 today (as of 01/26/2024). On a total return basis, that’s a result of 153.60% (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.]

Beyond share price change, another component of SLB’s total return these past 20 years has been the payment by Schlumberger Ltd of $22.49/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 1.1/share, we calculate that SLB has a current yield of approximately 2.08%. 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 $30.91/share purchase price. This works out to a yield on cost of 6.73%.

Another great investment quote to think about:
“If you are not willing to own a stock for 10 years, do not even think about owning it for 10 minutes.” — Warren Buffett
