“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

The above quote from Warren Buffett is timeless, and brings into focus the choice about time horizon that any investor should think about before buying a stock they are considering. Behind every stock is an actual business; what will that business look like over a two-decade period?

Today, let’s look backwards in time to 2002, and take a look at what happened to investors who asked that very question about Ecolab Inc (NYSE: ECL), by taking a look at the investment outcome over a two-decade holding period.

Start date: 02/25/2002
$10,000

02/25/2002
$98,147

02/24/2022
End date: 02/24/2022
Start price/share: $22.55
End price/share: $175.94
Starting shares: 443.46
Ending shares: 558.14
Dividends reinvested/share: $19.24
Total return: 881.99%
Average annual return: 12.09%
Starting investment: $10,000.00
Ending investment: $98,147.80

As we can see, the two-decade investment result worked out quite well, with an annualized rate of return of 12.09%. This would have turned a $10K investment made 20 years ago into $98,147.80 today (as of 02/24/2022). On a total return basis, that’s a result of 881.99% (something to think about: how might ECL shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Ecolab Inc paid investors a total of $19.24/share in dividends over the 20 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 2.04/share, we calculate that ECL has a current yield of approximately 1.16%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.04 against the original $22.55/share purchase price. This works out to a yield on cost of 5.14%.
