“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a decade-long period?

Today, let’s look backwards in time to 2009, and take a look at what happened to investors who asked that very question about ResMed Inc. (NYSE: RMD), by taking a look at the investment outcome over a decade-long holding period.

Start date: 08/31/2009
$10,000

08/31/2009
$68,734

08/29/2019
End date: 08/29/2019
Start price/share: $22.96
End price/share: $138.38
Starting shares: 435.54
Ending shares: 496.55
Dividends reinvested/share: $8.59
Total return: 587.13%
Average annual return: 21.26%
Starting investment: $10,000.00
Ending investment: $68,734.64

As we can see, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 21.26%. This would have turned a $10K investment made 10 years ago into $68,734.64 today (as of 08/29/2019). On a total return basis, that’s a result of 587.13% (something to think about: how might RMD shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that ResMed Inc. paid investors a total of $8.59/share in dividends over the 10 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 1.56/share, we calculate that RMD has a current yield of approximately 1.13%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.56 against the original $22.96/share purchase price. This works out to a yield on cost of 4.92%.
