“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 Ecolab Inc (NYSE: ECL)? Today, we examine the outcome of a five year investment into the stock back in 2017.

Start date: 12/28/2017
$10,000

12/28/2017
  $11,402

12/27/2022
End date: 12/27/2022
Start price/share: $134.53
End price/share: $145.45
Starting shares: 74.33
Ending shares: 78.41
Dividends reinvested/share: $9.44
Total return: 14.05%
Average annual return: 2.66%
Starting investment: $10,000.00
Ending investment: $11,402.66

As we can see, the five year investment result worked out as follows, with an annualized rate of return of 2.66%. This would have turned a $10K investment made 5 years ago into $11,402.66 today (as of 12/27/2022). On a total return basis, that’s a result of 14.05% (something to think about: how might ECL shares perform over the next 5 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Ecolab Inc paid investors a total of $9.44/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 2.12/share, we calculate that ECL has a current yield of approximately 1.46%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.12 against the original $134.53/share purchase price. This works out to a yield on cost of 1.09%.
