“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 Stanley Black & Decker Inc (NYSE: SWK)? Today, we examine the outcome of a ten year investment into the stock back in 2015.

Start date: 09/30/2015
$10,000

09/30/2015
  $9,801

09/29/2025
End date: 09/29/2025
Start price/share: $96.98
End price/share: $73.90
Starting shares: 103.11
Ending shares: 132.61
Dividends reinvested/share: $28.40
Total return: -2.00%
Average annual return: -0.20%
Starting investment: $10,000.00
Ending investment: $9,801.68

As shown above, the ten year investment result worked out poorly, with an annualized rate of return of -0.20%. This would have turned a $10K investment made 10 years ago into $9,801.68 today (as of 09/29/2025). On a total return basis, that’s a result of -2.00% (something to think about: how might SWK shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Stanley Black & Decker Inc paid investors a total of $28.40/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 3.32/share, we calculate that SWK has a current yield of approximately 4.49%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 3.32 against the original $96.98/share purchase price. This works out to a yield on cost of 4.63%.
