“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 Merck & Co Inc (NYSE: MRK)? Today, we examine the outcome of a five year investment into the stock back in 2015.

Start date: 08/28/2015
$10,000

08/28/2015
$18,058

08/27/2020
End date: 08/27/2020
Start price/share: $55.37
End price/share: $85.82
Starting shares: 180.60
Ending shares: 210.39
Dividends reinvested/share: $10.12
Total return: 80.55%
Average annual return: 12.54%
Starting investment: $10,000.00
Ending investment: $18,058.23

As we can see, the five year investment result worked out quite well, with an annualized rate of return of 12.54%. This would have turned a $10K investment made 5 years ago into $18,058.23 today (as of 08/27/2020). On a total return basis, that’s a result of 80.55% (something to think about: how might MRK shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Merck & Co Inc paid investors a total of $10.12/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 2.44/share, we calculate that MRK has a current yield of approximately 2.84%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.44 against the original $55.37/share purchase price. This works out to a yield on cost of 5.13%.
