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

— 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 two-decade period?

Today, let’s look backwards in time to 2000, and take a look at what happened to investors who asked that very question about Duke Energy Corp (NYSE: DUK), by taking a look at the investment outcome over a two-decade holding period.

Start date: 06/26/2000
$10,000

06/26/2000
$39,603

06/25/2020
End date: 06/25/2020
Start price/share: $51.54
End price/share: $79.45
Starting shares: 194.02
Ending shares: 498.75
Dividends reinvested/share: $56.56
Total return: 296.25%
Average annual return: 7.12%
Starting investment: $10,000.00
Ending investment: $39,603.96

As shown above, the two-decade investment result worked out well, with an annualized rate of return of 7.12%. This would have turned a $10K investment made 20 years ago into $39,603.96 today (as of 06/25/2020). On a total return basis, that’s a result of 296.25% (something to think about: how might DUK shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Duke Energy Corp paid investors a total of $56.56/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 3.78/share, we calculate that DUK has a current yield of approximately 4.76%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.78 against the original $51.54/share purchase price. This works out to a yield on cost of 9.24%.
