“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 Marathon Oil Corp. (NYSE: MRO), by taking a look at the investment outcome over a two-decade holding period.

Start date: 02/14/2000
$10,000

02/14/2000
$27,153

02/11/2020
End date: 02/11/2020
Start price/share: $6.97
End price/share: $11.57
Starting shares: 1,434.72
Ending shares: 2,348.51
Dividends reinvested/share: $8.79
Total return: 171.72%
Average annual return: 5.12%
Starting investment: $10,000.00
Ending investment: $27,153.50

The above analysis shows the two-decade investment result worked out well, with an annualized rate of return of 5.12%. This would have turned a $10K investment made 20 years ago into $27,153.50 today (as of 02/11/2020). On a total return basis, that’s a result of 171.72% (something to think about: how might MRO shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Marathon Oil Corp. paid investors a total of $8.79/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 .2/share, we calculate that MRO has a current yield of approximately 1.73%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .2 against the original $6.97/share purchase price. This works out to a yield on cost of 24.82%.
