“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a five year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into American Tower Corp (NYSE: AMT)? Today, we examine the outcome of a five year investment into the stock back in 2019.

Start date: 04/30/2019
$10,000

04/30/2019
  $10,105

04/29/2024
End date: 04/29/2024
Start price/share: $195.30
End price/share: $174.99
Starting shares: 51.20
Ending shares: 57.74
Dividends reinvested/share: $26.55
Total return: 1.04%
Average annual return: 0.21%
Starting investment: $10,000.00
Ending investment: $10,105.50

As we can see, the five year investment result worked out as follows, with an annualized rate of return of 0.21%. This would have turned a $10K investment made 5 years ago into $10,105.50 today (as of 04/29/2024). On a total return basis, that’s a result of 1.04% (something to think about: how might AMT shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that American Tower Corp paid investors a total of $26.55/share in dividends over the 5 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 6.48/share, we calculate that AMT has a current yield of approximately 3.70%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 6.48 against the original $195.30/share purchase price. This works out to a yield on cost of 1.89%.

Another great investment quote to think about:
“Unless you can watch your stock holding decline by 50% without becoming panic-stricken, you should not be in the stock market.” — Warren Buffett
