“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 UnitedHealth Group Inc (NYSE: UNH), by taking a look at the investment outcome over a decade-long holding period.

Start date: 05/29/2009
$10,000

05/29/2009
$104,336

05/28/2019
End date: 05/28/2019
Start price/share: $26.60
End price/share: $242.06
Starting shares: 375.94
Ending shares: 431.12
Dividends reinvested/share: $15.75
Total return: 943.57%
Average annual return: 26.42%
Starting investment: $10,000.00
Ending investment: $104,336.63

As we can see, the decade-long investment result worked out exceptionally well, with an annualized rate of return of 26.42%. This would have turned a $10K investment made 10 years ago into $104,336.63 today (as of 05/28/2019). On a total return basis, that’s a result of 943.57% (something to think about: how might UNH shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that UnitedHealth Group Inc paid investors a total of $15.75/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 3.6/share, we calculate that UNH has a current yield of approximately 1.49%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.6 against the original $26.60/share purchase price. This works out to a yield on cost of 5.60%.

One more investment quote to leave you with:
