“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 McKesson Corp (NYSE: MCK)? Today, we examine the outcome of a five year investment into the stock back in 2015.

Start date: 11/10/2015


End date: 11/09/2020
Start price/share: $184.66
End price/share: $178.51
Starting shares: 54.15
Ending shares: 56.79
Dividends reinvested/share: $6.94
Total return: 1.37%
Average annual return: 0.27%
Starting investment: $10,000.00
Ending investment: $10,135.81

As we can see, the five year investment result worked out as follows, with an annualized rate of return of 0.27%. This would have turned a $10K investment made 5 years ago into $10,135.81 today (as of 11/09/2020). On a total return basis, that’s a result of 1.37% (something to think about: how might MCK shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that McKesson Corp paid investors a total of $6.94/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 1.68/share, we calculate that MCK has a current yield of approximately 0.94%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.68 against the original $184.66/share purchase price. This works out to a yield on cost of 0.51%.
