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

— Warren Buffett

The investment philosophy practiced by Warren Buffett calls for investors to take a long-term horizon when making an investment, such as a five year holding period (or even longer), and reconsider making the investment in the first place if unable to envision holding the stock for at least five years. Today, we look at how such a long-term strategy would have done for investors in McKesson Corp (NYSE: MCK) back in 2018, holding through to today.

Start date: 09/06/2018


End date: 09/05/2023
Start price/share: $125.50
End price/share: $407.13
Starting shares: 79.68
Ending shares: 83.37
Dividends reinvested/share: $9.15
Total return: 239.42%
Average annual return: 27.69%
Starting investment: $10,000.00
Ending investment: $33,945.67

As shown above, the five year investment result worked out exceptionally well, with an annualized rate of return of 27.69%. This would have turned a $10K investment made 5 years ago into $33,945.67 today (as of 09/05/2023). On a total return basis, that’s a result of 239.42% (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.]

Beyond share price change, another component of MCK’s total return these past 5 years has been the payment by McKesson Corp of $9.15/share in dividends to shareholders. Automatic reinvestment of dividends can be a wonderful way to compound returns, and for the above calculations we presume that dividends are reinvested into additional shares of stock. (For the purpose of these calcuations, the closing price on ex-date is used).

Based upon the most recent annualized dividend rate of 2.48/share, we calculate that MCK has a current yield of approximately 0.61%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.48 against the original $125.50/share purchase price. This works out to a yield on cost of 0.49%.

“While some might mistakenly consider value investing a mechanical tool for identifying bargains, it is actually a comprehensive investment philosophy that emphasizes the need to perform in-depth fundamental analysis, pursue long-term investment results, limit risk, and resist crowd psychology.” — Seth Klarman
