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

— Warren Buffett

This inspiring quote from Warren Buffett teaches us the importance of considering our investment time horizon when approaching any given investment: Could we envision ourselves holding the stock we are considering for many years? Even a five year holding period potentially?

For “buy-and-hold” investors taking a long-term view, what’s important isn’t the short-term stock market fluctuations that will inevitably occur, but what happens over the long haul. Looking back 5 years to 2015, investors considering an investment into shares of American Express Co. (NYSE: AXP) may have been pondering this very question and thinking about their potential investment result over a full five year time horizon. Here’s how that would have worked out.

Start date: 12/18/2015
$10,000

12/18/2015
$19,017

12/17/2020
End date: 12/17/2020
Start price/share: $67.87
End price/share: $118.98
Starting shares: 147.34
Ending shares: 159.86
Dividends reinvested/share: $7.26
Total return: 90.21%
Average annual return: 13.71%
Starting investment: $10,000.00
Ending investment: $19,017.18

As we can see, the five year investment result worked out quite well, with an annualized rate of return of 13.71%. This would have turned a $10K investment made 5 years ago into $19,017.18 today (as of 12/17/2020). On a total return basis, that’s a result of 90.21% (something to think about: how might AXP shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that American Express Co. paid investors a total of $7.26/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 1.72/share, we calculate that AXP has a current yield of approximately 1.45%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.72 against the original $67.87/share purchase price. This works out to a yield on cost of 2.14%.
