“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

One of the most important things investors can learn from Warren Buffett, is about how they approach their time horizon for an investment into a stock under consideration. Because immediately after buying shares of a given stock, investors will then be able to check on the day-to-day (and even minute-by-minute) market value. Some days the stock market will be up, other days down. These daily fluctuations can often distract from the long-term view. Today, we look at the result of a twenty year holding period for an investor who was considering McKesson Corp (NYSE: MCK) back in 2002, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 02/04/2002


End date: 02/01/2022
Start price/share: $37.15
End price/share: $256.92
Starting shares: 269.18
Ending shares: 315.84
Dividends reinvested/share: $16.32
Total return: 711.47%
Average annual return: 11.03%
Starting investment: $10,000.00
Ending investment: $81,106.52

The above analysis shows the twenty year investment result worked out quite well, with an annualized rate of return of 11.03%. This would have turned a $10K investment made 20 years ago into $81,106.52 today (as of 02/01/2022). On a total return basis, that’s a result of 711.47% (something to think about: how might MCK shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that McKesson Corp paid investors a total of $16.32/share in dividends over the 20 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 1.88/share, we calculate that MCK has a current yield of approximately 0.73%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.88 against the original $37.15/share purchase price. This works out to a yield on cost of 1.97%.
