“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 Williams Cos Inc (NYSE: WMB)? Today, we examine the outcome of a twenty year investment into the stock back in 2000.

Start date: 05/15/2000
$10,000

05/15/2000
$12,471

05/12/2020
End date: 05/12/2020
Start price/share: $29.98
End price/share: $19.08
Starting shares: 333.56
Ending shares: 653.65
Dividends reinvested/share: $17.23
Total return: 24.72%
Average annual return: 1.11%
Starting investment: $10,000.00
Ending investment: $12,471.21

As we can see, the twenty year investment result worked out as follows, with an annualized rate of return of 1.11%. This would have turned a $10K investment made 20 years ago into $12,471.21 today (as of 05/12/2020). On a total return basis, that’s a result of 24.72% (something to think about: how might WMB shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Williams Cos Inc paid investors a total of $17.23/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 1.6/share, we calculate that WMB has a current yield of approximately 8.39%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.6 against the original $29.98/share purchase price. This works out to a yield on cost of 27.99%.
