“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a two-decade holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into American Tower Corp (NYSE: AMT) back in 2000: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full two-decade investment time horizon and then actually held for these past 20 years, here’s how that investment would have turned out.

Start date: 09/29/2000
$10,000

09/29/2000
$74,818

09/28/2020
End date: 09/28/2020
Start price/share: $37.69
End price/share: $240.00
Starting shares: 265.34
Ending shares: 311.51
Dividends reinvested/share: $20.60
Total return: 647.63%
Average annual return: 10.58%
Starting investment: $10,000.00
Ending investment: $74,818.73

As shown above, the two-decade investment result worked out quite well, with an annualized rate of return of 10.58%. This would have turned a $10K investment made 20 years ago into $74,818.73 today (as of 09/28/2020). On a total return basis, that’s a result of 647.63% (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 $20.60/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 4.56/share, we calculate that AMT has a current yield of approximately 1.90%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 4.56 against the original $37.69/share purchase price. This works out to a yield on cost of 5.04%.
