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

— 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 five year holding period for an investor who was considering ResMed Inc. (NYSE: RMD) back in 2016, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 10/13/2016
$10,000

10/13/2016
$42,182

10/12/2021
End date: 10/12/2021
Start price/share: $63.85
End price/share: $252.25
Starting shares: 156.62
Ending shares: 167.23
Dividends reinvested/share: $7.41
Total return: 321.84%
Average annual return: 33.36%
Starting investment: $10,000.00
Ending investment: $42,182.07

As shown above, the five year investment result worked out exceptionally well, with an annualized rate of return of 33.36%. This would have turned a $10K investment made 5 years ago into $42,182.07 today (as of 10/12/2021). On a total return basis, that’s a result of 321.84% (something to think about: how might RMD shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that ResMed Inc. paid investors a total of $7.41/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 1.68/share, we calculate that RMD has a current yield of approximately 0.67%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.68 against the original $63.85/share purchase price. This works out to a yield on cost of 1.05%.

Another great investment quote to think about:
“If you are not willing to own a stock for 10 years, do not even think about owning it for 10 minutes.” — Warren Buffett
