“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a two-decade holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of UnitedHealth Group Inc (NYSE: UNH) back in 2004. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 08/09/2004
$10,000

08/09/2004
  $230,465

08/06/2024
End date: 08/06/2024
Start price/share: $30.69
End price/share: $568.35
Starting shares: 325.84
Ending shares: 405.46
Dividends reinvested/share: $47.20
Total return: 2,204.41%
Average annual return: 16.98%
Starting investment: $10,000.00
Ending investment: $230,465.31

As we can see, the two-decade investment result worked out exceptionally well, with an annualized rate of return of 16.98%. This would have turned a $10K investment made 20 years ago into $230,465.31 today (as of 08/06/2024). On a total return basis, that’s a result of 2,204.41% (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 $47.20/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 8.4/share, we calculate that UNH has a current yield of approximately 1.48%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 8.4 against the original $30.69/share purchase price. This works out to a yield on cost of 4.82%.
