“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 3M Co (NYSE: MMM)? Today, we examine the outcome of a ten year investment into the stock back in 2013.

Start date: 03/18/2013
$10,000

03/18/2013
  $13,141

03/15/2023
End date: 03/15/2023
Start price/share: $105.41
End price/share: $102.78
Starting shares: 94.87
Ending shares: 127.91
Dividends reinvested/share: $49.02
Total return: 31.46%
Average annual return: 2.77%
Starting investment: $10,000.00
Ending investment: $13,141.08

As shown above, the ten year investment result worked out as follows, with an annualized rate of return of 2.77%. This would have turned a $10K investment made 10 years ago into $13,141.08 today (as of 03/15/2023). On a total return basis, that’s a result of 31.46% (something to think about: how might MMM shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that 3M Co paid investors a total of $49.02/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 6/share, we calculate that MMM has a current yield of approximately 5.84%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 6 against the original $105.41/share purchase price. This works out to a yield on cost of 5.54%.

One more piece of investment wisdom to leave you with:
“The ideal business is one that earns very high returns on capital and that keeps using lots of capital at those high returns. That becomes a compounding machine.” — Warren Buffett
