“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 twenty year period?

Today, let’s look backwards in time to 1999, and take a look at what happened to investors who asked that very question about Smith (A O) Corp (NYSE: AOS), by taking a look at the investment outcome over a twenty year holding period.

Start date: 03/22/1999
$10,000

03/22/1999
$224,144

03/19/2019
End date: 03/19/2019
Start price/share: $3.32
End price/share: $52.13
Starting shares: 3,012.05
Ending shares: 4,296.92
Dividends reinvested/share: $4.50
Total return: 2,139.98%
Average annual return: 16.82%
Starting investment: $10,000.00
Ending investment: $224,144.98

As shown above, the twenty year investment result worked out exceptionally well, with an annualized rate of return of 16.82%. This would have turned a $10K investment made 20 years ago into $224,144.98 today (as of 03/19/2019). On a total return basis, that’s a result of 2,139.98% (something to think about: how might AOS shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Smith (A O) Corp paid investors a total of $4.50/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 .88/share, we calculate that AOS has a current yield of approximately 1.69%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of .88 against the original $3.32/share purchase price. This works out to a yield on cost of 50.90%.
