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

— Warren Buffett

Such a great quote from Warren Buffett, highlighting the importance of investment time horizon when considering making an investment. In the short run, who knows what the stock market will do? A week or two after buying any given stock, could the entire stock market fall out of bed? Quite possibly! Should that happen, how would you react? It is an excellent question to think about before hitting the buy button.

For investors who take a multi-year time horizon, the important thing is not what happens in the next week or two, but what the result will be over the long haul. Today, we look at the result investors of the year 2010 experienced, who considered an investment in shares of UnitedHealth Group Inc (NYSE: UNH) and decided upon a decade-long investment time horizon.

Start date: 01/22/2010
$10,000

01/22/2010
$105,248

01/21/2020
End date: 01/21/2020
Start price/share: $33.16
End price/share: $300.53
Starting shares: 301.57
Ending shares: 350.30
Dividends reinvested/share: $18.99
Total return: 952.77%
Average annual return: 26.53%
Starting investment: $10,000.00
Ending investment: $105,248.29

The above analysis shows the decade-long investment result worked out exceptionally well, with an annualized rate of return of 26.53%. This would have turned a $10K investment made 10 years ago into $105,248.29 today (as of 01/21/2020). On a total return basis, that’s a result of 952.77% (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.]

Beyond share price change, another component of UNH’s total return these past 10 years has been the payment by UnitedHealth Group Inc of $18.99/share in dividends to shareholders. Automatic reinvestment of dividends can be a wonderful way to compound returns, and for the above calculations we presume that dividends are reinvested into additional shares of stock. (For the purpose of these calcuations, the closing price on ex-date is used).

Based upon the most recent annualized dividend rate of 4.32/share, we calculate that UNH has a current yield of approximately 1.44%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 4.32 against the original $33.16/share purchase price. This works out to a yield on cost of 4.34%.
