“When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.”
— 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 two-decade holding period for an investor who was considering Martin Marietta Materials, Inc. (NYSE: MLM) back in 1999, bought the stock, ignored the market’s ups and downs, and simply held through to today.
| Start date: | 05/13/1999 |

|||
| End date: | 05/10/2019 | ||||
| Start price/share: | $67.75 | ||||
| End price/share: | $215.87 | ||||
| Starting shares: | 147.60 | ||||
| Ending shares: | 195.49 | ||||
| Dividends reinvested/share: | $25.00 | ||||
| Total return: | 322.00% | ||||
| Average annual return: | 7.46% | ||||
| Starting investment: | $10,000.00 | ||||
| Ending investment: | $42,180.13 | ||||
As we can see, the two-decade investment result worked out well, with an annualized rate of return of 7.46%. This would have turned a $10K investment made 20 years ago into $42,180.13 today (as of 05/10/2019). On a total return basis, that’s a result of 322.00% (something to think about: how might MLM shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]
Notice that Martin Marietta Materials, Inc. paid investors a total of $25.00/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 1.92/share, we calculate that MLM has a current yield of approximately 0.89%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 1.92 against the original $67.75/share purchase price. This works out to a yield on cost of 1.31%.
Another great investment quote to think about:
“Although it’s easy to forget sometimes, a share is not a lottery ticket… it’s part-ownership of a business.” — Peter Lynch
