“Only buy something that you’d be perfectly happy to hold if the market shut down for 10 years.”

— 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 ten year holding period for an investor who was considering Mastercard Inc (NYSE: MA) back in 2012, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 08/20/2012


End date: 08/18/2022
Start price/share: $42.72
End price/share: $357.36
Starting shares: 234.08
Ending shares: 248.05
Dividends reinvested/share: $10.11
Total return: 786.43%
Average annual return: 24.38%
Starting investment: $10,000.00
Ending investment: $88,614.65

The above analysis shows the ten year investment result worked out exceptionally well, with an annualized rate of return of 24.38%. This would have turned a $10K investment made 10 years ago into $88,614.65 today (as of 08/18/2022). On a total return basis, that’s a result of 786.43% (something to think about: how might MA shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Mastercard Inc paid investors a total of $10.11/share in dividends over the 10 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 1.96/share, we calculate that MA has a current yield of approximately 0.55%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.96 against the original $42.72/share purchase price. This works out to a yield on cost of 1.29%.
