“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 decade-long holding period for an investor who was considering Medtronic PLC (NYSE: MDT) back in 2013, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 08/26/2013


End date: 08/23/2023
Start price/share: $52.37
End price/share: $83.68
Starting shares: 190.95
Ending shares: 237.88
Dividends reinvested/share: $19.05
Total return: 99.06%
Average annual return: 7.13%
Starting investment: $10,000.00
Ending investment: $19,908.07

As shown above, the decade-long investment result worked out well, with an annualized rate of return of 7.13%. This would have turned a $10K investment made 10 years ago into $19,908.07 today (as of 08/23/2023). On a total return basis, that’s a result of 99.06% (something to think about: how might MDT shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Medtronic PLC paid investors a total of $19.05/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 2.76/share, we calculate that MDT has a current yield of approximately 3.30%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.76 against the original $52.37/share purchase price. This works out to a yield on cost of 6.30%.
