“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— 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 decade-long period?

Today, let’s look backwards in time to 2009, and take a look at what happened to investors who asked that very question about American Electric Power Co Inc (NYSE: AEP), by taking a look at the investment outcome over a decade-long holding period.

Start date: 07/24/2009
$10,000

07/24/2009
$43,790

07/23/2019
End date: 07/23/2019
Start price/share: $30.94
End price/share: $89.51
Starting shares: 323.21
Ending shares: 489.04
Dividends reinvested/share: $20.92
Total return: 337.74%
Average annual return: 15.91%
Starting investment: $10,000.00
Ending investment: $43,790.99

The above analysis shows the decade-long investment result worked out exceptionally well, with an annualized rate of return of 15.91%. This would have turned a $10K investment made 10 years ago into $43,790.99 today (as of 07/23/2019). On a total return basis, that’s a result of 337.74% (something to think about: how might AEP shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that American Electric Power Co Inc paid investors a total of $20.92/share in dividends over the 10 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 2.68/share, we calculate that AEP has a current yield of approximately 2.99%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.68 against the original $30.94/share purchase price. This works out to a yield on cost of 9.66%.

Another great investment quote to think about:
“I believe in the discipline of mastering the best that other people have ever figured out. I don’t believe in just sitting down and trying to dream it all up yourself. Nobody’s that smart.” — Charlie Munger
