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

— 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 Express Co. (NYSE: AXP) back in 2002: 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: 01/14/2002
$10,000

01/14/2002
$73,569

01/11/2022
End date: 01/11/2022
Start price/share: $31.73
End price/share: $175.38
Starting shares: 315.16
Ending shares: 419.12
Dividends reinvested/share: $18.48
Total return: 635.05%
Average annual return: 10.49%
Starting investment: $10,000.00
Ending investment: $73,569.34

The above analysis shows the two-decade investment result worked out quite well, with an annualized rate of return of 10.49%. This would have turned a $10K investment made 20 years ago into $73,569.34 today (as of 01/11/2022). On a total return basis, that’s a result of 635.05% (something to think about: how might AXP shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that American Express Co. paid investors a total of $18.48/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 1.72/share, we calculate that AXP has a current yield of approximately 0.98%. 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 $31.73/share purchase price. This works out to a yield on cost of 3.09%.

Here’s one more great investment quote before you go:
“October is one of the peculiarly dangerous months to speculate in stocks. The others are July, January, September, April, November, May, March, June, December, August and February.” — Mark Twain
