“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— 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 twenty year holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of American Tower Corp (NYSE: AMT) back in 2000. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 02/14/2000
$10,000

02/14/2000
$66,371

02/13/2020
End date: 02/13/2020
Start price/share: $44.88
End price/share: $256.90
Starting shares: 222.84
Ending shares: 258.16
Dividends reinvested/share: $17.28
Total return: 563.20%
Average annual return: 9.92%
Starting investment: $10,000.00
Ending investment: $66,371.95

As we can see, the twenty year investment result worked out well, with an annualized rate of return of 9.92%. This would have turned a $10K investment made 20 years ago into $66,371.95 today (as of 02/13/2020). On a total return basis, that’s a result of 563.20% (something to think about: how might AMT shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that American Tower Corp paid investors a total of $17.28/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 4.04/share, we calculate that AMT has a current yield of approximately 1.57%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 4.04 against the original $44.88/share purchase price. This works out to a yield on cost of 3.50%.
