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

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a two-decade holding period for an investor who was considering Cummins, Inc. (NYSE: CMI) back in 2001, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 10/04/2001
$10,000

10/04/2001
$415,664

10/01/2021
End date: 10/01/2021
Start price/share: $8.49
End price/share: $227.96
Starting shares: 1,177.86
Ending shares: 1,822.49
Dividends reinvested/share: $42.84
Total return: 4,054.56%
Average annual return: 20.48%
Starting investment: $10,000.00
Ending investment: $415,664.13

As we can see, the two-decade investment result worked out exceptionally well, with an annualized rate of return of 20.48%. This would have turned a $10K investment made 20 years ago into $415,664.13 today (as of 10/01/2021). On a total return basis, that’s a result of 4,054.56% (something to think about: how might CMI shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Cummins, Inc. paid investors a total of $42.84/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 5.8/share, we calculate that CMI has a current yield of approximately 2.54%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 5.8 against the original $8.49/share purchase price. This works out to a yield on cost of 29.92%.

Another great investment quote to think about:
