“I buy on the assumption that they could close the market the next day and not reopen it for five 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 five year holding period for an investor who was considering Marsh & McLennan Companies Inc. (NYSE: MMC) back in 2018, bought the stock, ignored the market’s ups and downs, and simply held through to today.

Start date: 12/03/2018
$10,000

12/03/2018
  $24,233

11/30/2023
End date: 11/30/2023
Start price/share: $89.10
End price/share: $199.42
Starting shares: 112.23
Ending shares: 121.50
Dividends reinvested/share: $10.43
Total return: 142.29%
Average annual return: 19.39%
Starting investment: $10,000.00
Ending investment: $24,233.60

As shown above, the five year investment result worked out exceptionally well, with an annualized rate of return of 19.39%. This would have turned a $10K investment made 5 years ago into $24,233.60 today (as of 11/30/2023). On a total return basis, that’s a result of 142.29% (something to think about: how might MMC shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Marsh & McLennan Companies Inc. paid investors a total of $10.43/share in dividends over the 5 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 2.84/share, we calculate that MMC has a current yield of approximately 1.42%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.84 against the original $89.10/share purchase price. This works out to a yield on cost of 1.59%.
