“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a ten year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Williams Cos Inc (NYSE: WMB) back in 2009. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 06/24/2009
$10,000

06/24/2009
$35,590

06/21/2019
End date: 06/21/2019
Start price/share: $12.15
End price/share: $27.70
Starting shares: 823.05
Ending shares: 1,284.60
Dividends reinvested/share: $13.25
Total return: 255.83%
Average annual return: 13.54%
Starting investment: $10,000.00
Ending investment: $35,590.80

As shown above, the ten year investment result worked out quite well, with an annualized rate of return of 13.54%. This would have turned a $10K investment made 10 years ago into $35,590.80 today (as of 06/21/2019). On a total return basis, that’s a result of 255.83% (something to think about: how might WMB shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Williams Cos Inc paid investors a total of $13.25/share in dividends over the 10 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 1.52/share, we calculate that WMB has a current yield of approximately 5.49%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.52 against the original $12.15/share purchase price. This works out to a yield on cost of 45.19%.
