“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— 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 UnitedHealth Group Inc (NYSE: UNH) back in 1999, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 06/28/1999
$10,000

06/28/1999
$357,340

06/26/2019
End date: 06/26/2019
Start price/share: $7.89
End price/share: $243.47
Starting shares: 1,267.43
Ending shares: 1,467.29
Dividends reinvested/share: $16.98
Total return: 3,472.42%
Average annual return: 19.57%
Starting investment: $10,000.00
Ending investment: $357,340.78

The above analysis shows the twenty year investment result worked out exceptionally well, with an annualized rate of return of 19.57%. This would have turned a $10K investment made 20 years ago into $357,340.78 today (as of 06/26/2019). On a total return basis, that’s a result of 3,472.42% (something to think about: how might UNH shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that UnitedHealth Group Inc paid investors a total of $16.98/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 4.32/share, we calculate that UNH has a current yield of approximately 1.77%. 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 $7.89/share purchase price. This works out to a yield on cost of 22.43%.
