“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

Investors can learn a lot from Warren Buffett, whose above quote teaches the importance of thinking about investment time horizon, and asking ourselves before buying any given stock: can we envision holding onto it for years — even a five year holding period possibly?

Suppose a “buy-and-hold” investor was considering an investment into Cintas Corporation (NASD: CTAS) back in 2018: back then, such an investor may have been pondering this very same question. Had they answered “yes” to a full five year investment time horizon and then actually held for these past 5 years, here’s how that investment would have turned out.

Start date: 04/16/2018
$10,000

04/16/2018
  $28,041

04/13/2023
End date: 04/13/2023
Start price/share: $172.91
End price/share: $459.78
Starting shares: 57.83
Ending shares: 60.99
Dividends reinvested/share: $16.86
Total return: 180.40%
Average annual return: 22.93%
Starting investment: $10,000.00
Ending investment: $28,041.30

As we can see, the five year investment result worked out exceptionally well, with an annualized rate of return of 22.93%. This would have turned a $10K investment made 5 years ago into $28,041.30 today (as of 04/13/2023). On a total return basis, that’s a result of 180.40% (something to think about: how might CTAS shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Cintas Corporation paid investors a total of $16.86/share in dividends over the 5 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 4.6/share, we calculate that CTAS has a current yield of approximately 1.00%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 4.6 against the original $172.91/share purchase price. This works out to a yield on cost of 0.58%.
