“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 twenty year holding period for an investor who was considering ResMed Inc. (NYSE: RMD) back in 2003, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 12/04/2003
$10,000

12/04/2003
  $187,832

12/01/2023
End date: 12/01/2023
Start price/share: $10.05
End price/share: $159.64
Starting shares: 995.02
Ending shares: 1,176.06
Dividends reinvested/share: $15.72
Total return: 1,777.46%
Average annual return: 15.79%
Starting investment: $10,000.00
Ending investment: $187,832.16

As shown above, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 15.79%. This would have turned a $10K investment made 20 years ago into $187,832.16 today (as of 12/01/2023). On a total return basis, that’s a result of 1,777.46% (something to think about: how might RMD shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that ResMed Inc. paid investors a total of $15.72/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 1.92/share, we calculate that RMD has a current yield of approximately 1.20%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.92 against the original $10.05/share purchase price. This works out to a yield on cost of 11.94%.
