“I buy on the assumption that they could close the market the next day and not reopen it for five years.”

— Warren Buffett

The Warren Buffett investment philosophy calls for a long-term investment horizon, where a five year holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into 3M Co (NYSE: MMM)? Today, we examine the outcome of a five year investment into the stock back in 2014.

Start date: 12/16/2014
$10,000

12/16/2014
$12,152

12/13/2019
End date: 12/13/2019
Start price/share: $159.05
End price/share: $168.79
Starting shares: 62.87
Ending shares: 71.98
Dividends reinvested/share: $24.44
Total return: 21.50%
Average annual return: 3.98%
Starting investment: $10,000.00
Ending investment: $12,152.24

The above analysis shows the five year investment result worked out as follows, with an annualized rate of return of 3.98%. This would have turned a $10K investment made 5 years ago into $12,152.24 today (as of 12/13/2019). On a total return basis, that’s a result of 21.50% (something to think about: how might MMM shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that 3M Co paid investors a total of $24.44/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 5.76/share, we calculate that MMM has a current yield of approximately 3.41%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 5.76 against the original $159.05/share purchase price. This works out to a yield on cost of 2.14%.
