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

— 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 Xcel Energy Inc (NASD: XEL) back in 2000, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 02/22/2000
$10,000

02/22/2000
$91,507

02/20/2020
End date: 02/20/2020
Start price/share: $18.31
End price/share: $70.67
Starting shares: 546.08
Ending shares: 1,293.93
Dividends reinvested/share: $22.50
Total return: 814.42%
Average annual return: 11.70%
Starting investment: $10,000.00
Ending investment: $91,507.86

As we can see, the twenty year investment result worked out quite well, with an annualized rate of return of 11.70%. This would have turned a $10K investment made 20 years ago into $91,507.86 today (as of 02/20/2020). On a total return basis, that’s a result of 814.42% (something to think about: how might XEL shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Xcel Energy Inc paid investors a total of $22.50/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 1.62/share, we calculate that XEL has a current yield of approximately 2.29%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.62 against the original $18.31/share purchase price. This works out to a yield on cost of 12.51%.
