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

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a ten year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Marsh & McLennan Companies Inc. (NYSE: MMC)? Today, we examine the outcome of a ten year investment into the stock back in 2009.

Start date: 10/22/2009
$10,000

10/22/2009
$50,013

10/21/2019
End date: 10/21/2019
Start price/share: $25.27
End price/share: $99.74
Starting shares: 395.73
Ending shares: 501.64
Dividends reinvested/share: $11.82
Total return: 400.33%
Average annual return: 17.46%
Starting investment: $10,000.00
Ending investment: $50,013.98

As shown above, the ten year investment result worked out exceptionally well, with an annualized rate of return of 17.46%. This would have turned a $10K investment made 10 years ago into $50,013.98 today (as of 10/21/2019). On a total return basis, that’s a result of 400.33% (something to think about: how might MMC shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Marsh & McLennan Companies Inc. paid investors a total of $11.82/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 1.82/share, we calculate that MMC has a current yield of approximately 1.82%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.82 against the original $25.27/share purchase price. This works out to a yield on cost of 7.20%.
