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

— Warren Buffett

Such a great quote from Warren Buffett, highlighting the importance of investment time horizon when considering making an investment. In the short run, who knows what the stock market will do? A week or two after buying any given stock, could the entire stock market fall out of bed? Quite possibly! Should that happen, how would you react? It is an excellent question to think about before hitting the buy button.

For investors who take a multi-year time horizon, the important thing is not what happens in the next week or two, but what the result will be over the long haul. Today, we look at the result investors of the year 2009 experienced, who considered an investment in shares of Comerica, Inc. (NYSE: CMA) and decided upon a decade-long investment time horizon.

Start date: 09/11/2009
$10,000

09/11/2009
$27,419

09/10/2019
End date: 09/10/2019
Start price/share: $27.60
End price/share: $64.07
Starting shares: 362.32
Ending shares: 427.94
Dividends reinvested/share: $8.76
Total return: 174.18%
Average annual return: 10.61%
Starting investment: $10,000.00
Ending investment: $27,419.78

As shown above, the decade-long investment result worked out quite well, with an annualized rate of return of 10.61%. This would have turned a $10K investment made 10 years ago into $27,419.78 today (as of 09/10/2019). On a total return basis, that’s a result of 174.18% (something to think about: how might CMA shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Comerica, Inc. paid investors a total of $8.76/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 CMA has a current yield of approximately 4.18%. 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 $27.60/share purchase price. This works out to a yield on cost of 15.14%.

One more investment quote to leave you with:
