From these data, we can plot Sales, EBIT, and EPS versus Year, as shown in the chart below.

Sales (in Millions), EBIT (in Millions), and EPS versus Year for Ecolab, 2002-2011

As evident from the chart above, ECL has demonstrated quite predictable sales and earnings over the past 10 years, allowing us to predict EPS in the near future, say in five years (i.e. Year 2016), using the linear regression equation for EPS = 0.1587 (2016) - 316.83 = 3.1092.

A conservative average P/E estimate for the stock can be obtained as follows:

Signature P/E: A well established stock has a signature P/E, an average P/E it commands in the market based on its business. We calculate this by averaging the Average P/E over the past 10 years, excluding any outliers (data points that fall significantly beyond the other data points). There are no significant outliers, so we average the Average P/Es from the past 10 years to arrive at a signature P/E of 25.7.

High P/E estimate: a conservative high P/E estimate can be calculated by averaging the five lowest High P/Es of the 10 High P/Es from the past 10 years. Averaging the 5 lowest High P/Es from the past 10 years gives 27.4.

Low P/E estimate: a conservative low P/E estimate can be calculated by averaging the five lowest Low P/Es of the 10 High P/Es from the past 10 years. Averaging the 5 lowest Low P/Es from the past 10 years gives 19.7.

Average P/E estimate: this takes the average of the High P/E estimate and the Low P/E estimate, as calculated above, to give a conservative estimate of an average P/E for the stock we can expect. Averaging 27.4 and 19.7 gives us 23.55.

Target Price

Multiplying our EPS projection for 5 years hence by the average P/E estimate gives us a projected average price for the stock: $3.1092 * 23.55 = $73.21, which represents an annual stock price return of 5.1% from the current price = $60. When we add in the 1.3% dividend yield, the total return expected is an annualized 6.4%, which means an investment in ECL today is expected to double in about 11 years.

Given a beta = 0.71 for ECL, a risk-free rate = 2% (using the yield on 10-year Treasury bond as a benchmark), and estimated risk premium of about 5% for the general stock market, we have a discount rate = 2% + 0.71*(5%) = 5.55%. Applying this discount rate of 5.55%, our projected price of $73.21 in 5 years translates to a target price = $56 in today's dollars, which is 7% below the current price of $60 for the stock. For a good margin of safety, investors are well advised to buy only if the current price is at least 20% below the target price, which means a buy price of $45.

Market Expectation

What is the market's expectation of ECL's growth rate given its current market price = $60? Since stock price = dividend * (1 + growth rate) / (discount rate - growth rate), we have growth rate = ((stock price) * (discount rate) - dividend) / (stock price + dividend). Plugging in stock price = $60, dividend rate = $0.80, and discount rate = 5.55%, we get growth rate = 4.2%. This seems reasonable, given that ECL has grown its revenue by 6%, its earnings by 11%, and its dividend by 12% annually over the past 5 years. The growth rate is supposed to slow down a bit as a company matures, so an implied market expected growth rate of 4.2% suggests that the stock is currently fairly valued.

Current P/E Compared With Signature P/E

As an additional consideration, we should also determine how the stock's current P/E compares with its signature P/E, since established stocks tend to revert back to their respective signature P/Es over the long term. The current EPS = 2.14, giving us a current P/E = 28. This is about 109% of the stock's signature P/E of 25.7, again suggesting the stock is fairly price right now. To provide some margin for error, we should look to buy when the current P/E is 80% or less of the stock's signature P/E, which means a buy price around $44.

Risk Index

Lastly, we calculate the Risk Index, calculated as (Current Price - Forecast Low Price)/ (Potential High Price - Forecast Low Price) to give an estimate of the risk: reward ratio. Risk index less than 20% is desired, which gives us +200% potential returns for every risk of 50% loss we assume.

The Forecast Low Price is calculated by multiplying the Low P/E estimate by the Forecast Low EPS, to give a conservative estimate of low price for the stock in 5 years, assuming zero EPS growth and low valuation. Forecast Low EPS is estimated by averaging the EPS over the past 5 years. For growth stocks with predictable earnings growth, EPS in 5 years should not be any lower than this conservative estimate. For ECL, the forecast low EPS is equal to 1.78, so the Forecast Low Price = 19.7 * 1.78 = $35.03.

The Potential High Price is calculated by multiplying the High P/E estimate by the projected EPS in 5 years, giving us a price target in 5 years should the stock command a high P/E. For ECL, this equals 27.4 * 3.1092 = $85.24.

Thus, the Risk Index = ($60 - $35.03) / ($85.24 - $35.03) = 50%. Since this is significantly greater than 20%, the stock has an unfavorable reward to risk ratio at the current price. A pullback to $45 would give a risk index less than 20%.


Ecolab, Inc., currently selling at an all-time high around $60, has a target price = $56. Its current P/E of 28 is higher than its historic P/E of 25.7, and its downside risk outweighs its upside potential. Therefore, I rate the stock a HOLD at the current price. A pullback to $45 would provide conservative investors enough margin of safety to buy as a long-term investment.
