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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a two-decade holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Comerica, Inc. (NYSE: CMA)? Today, we examine the outcome of a two-decade investment into the stock back in 2000.

Start date: 01/18/2000
$10,000

01/18/2000
$28,156

01/16/2020
End date: 01/16/2020
Start price/share: $43.06
End price/share: $68.24
Starting shares: 232.22
Ending shares: 412.60
Dividends reinvested/share: $28.99
Total return: 181.56%
Average annual return: 5.31%
Starting investment: $10,000.00
Ending investment: $28,156.39

The above analysis shows the two-decade investment result worked out well, with an annualized rate of return of 5.31%. This would have turned a $10K investment made 20 years ago into $28,156.39 today (as of 01/16/2020). On a total return basis, that’s a result of 181.56% (something to think about: how might CMA shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Comerica, Inc. paid investors a total of $28.99/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 2.68/share, we calculate that CMA has a current yield of approximately 3.93%. 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 $43.06/share purchase price. This works out to a yield on cost of 9.13%.

One more piece of investment wisdom to leave you with:
