“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 decade-long holding period, or even longer, would fit right into the strategy. How would such a strategy have worked out for an investment into Rockwell Automation, Inc. (NYSE: ROK)? Today, we examine the outcome of a decade-long investment into the stock back in 2013.

Start date: 01/30/2013


End date: 01/27/2023
Start price/share: $88.12
End price/share: $286.46
Starting shares: 113.48
Ending shares: 139.56
Dividends reinvested/share: $33.78
Total return: 299.78%
Average annual return: 14.87%
Starting investment: $10,000.00
Ending investment: $39,985.38

As shown above, the decade-long investment result worked out quite well, with an annualized rate of return of 14.87%. This would have turned a $10K investment made 10 years ago into $39,985.38 today (as of 01/27/2023). On a total return basis, that’s a result of 299.78% (something to think about: how might ROK shares perform over the next 10 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Always an important consideration with a dividend-paying company is: should we reinvest our dividends?Over the past 10 years, Rockwell Automation, Inc. has paid $33.78/share in dividends. For the above analysis, we assume that the investor reinvests dividends into new shares of stock (for the above calculations, the reinvestment is performed using closing price on ex-div date for that dividend).

Based upon the most recent annualized dividend rate of 4.72/share, we calculate that ROK has a current yield of approximately 1.65%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 4.72 against the original $88.12/share purchase price. This works out to a yield on cost of 1.87%.
