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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a five year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Zoetis Inc (NYSE: ZTS)? Today, we examine the outcome of a five year investment into the stock back in 2020.

Start date: 10/08/2020
$10,000

10/08/2020
  $9,117

10/07/2025
End date: 10/07/2025
Start price/share: $163.17
End price/share: $142.77
Starting shares: 61.29
Ending shares: 63.86
Dividends reinvested/share: $6.90
Total return: -8.83%
Average annual return: -1.83%
Starting investment: $10,000.00
Ending investment: $9,117.88

As shown above, the five year investment result worked out poorly, with an annualized rate of return of -1.83%. This would have turned a $10K investment made 5 years ago into $9,117.88 today (as of 10/07/2025). On a total return basis, that’s a result of -8.83% (something to think about: how might ZTS shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Zoetis Inc paid investors a total of $6.90/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 2/share, we calculate that ZTS has a current yield of approximately 1.40%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2 against the original $163.17/share purchase price. This works out to a yield on cost of 0.86%.
