Zurn Elkay Water Solutions Corporation and Pentair plc Stock Value Grades

Company	Ticker	Value
Zurn Elkay Water Solutions Corporation	ZWS	F
Pentair plc	PNR	D

Successful stock investing involves buying low and selling high, so stock valuation is an important consideration for stock selection.

Buying stocks that are going to go up typically means buying stocks that are undervalued in the first place, although momentum investors may argue that point.

AAII’s A+ Investor Value Grade derives from a stock’s value score. The Value Score is the percentile rank of the average of the percentile ranks of the price-to-sales ratio, price-earnings ratio, enterprise-value-to-EBITDA (EV/EBITDA) ratio, shareholder yield, price-to-book-value ratio and price-to-free-cash-flow ratio. The score is variable, meaning it can consider all six ratios or, should any of the six ratios not be valid, the remaining ratios that are valid. To be assigned a Value Score, stocks must have a valid (non-null) ratio and corresponding ranking for at least two of the six valuation ratios.

Stocks with a Value Score from 81 to 100 are considered deep value, those with a score between 61 and 80 are a good value and so on.

Zurn Elkay Water Solutions Corporation has a Value Score of 18, which is Ultra Expensive. Pentair plc has a Value Score of 33, which is Expensive.

The Value Stock Winner: No Clear Winner

Neither Zurn Elkay Water Solutions Corporation or Pentair plc has a high enough value grade to be considered a “winner.” Investors who are considering these companies should do additional due diligence and research to see if either could be a good addition to their portfolio.

Zurn Elkay Water Solutions Corporation and Pentair plc’s Quality Grades

Company	Ticker	Quality
Zurn Elkay Water Solutions Corporation	ZWS	A
Pentair plc	PNR	A

Like the Value Grade, AAII’s A+ Investor Quality Grade comes from the percentile rank of key metrics. Specifically, the Quality Score is the percentile rank of the average of the percentile ranks of return on assets (ROA), return on invested capital (ROIC), gross profit relative to assets, buyback yield, change in total liabilities to assets, accruals, Z double prime bankruptcy risk (Z) score and the F-Score.

The score is variable, meaning it can consider all eight measures or, should any of the eight measures not be valid, the remaining measures that are valid. To be assigned a Quality Score, stocks must have a valid (non-null) measure and corresponding ranking for at least four of the eight quality measures.

The Quality Score is used to assess the underlying “quality” of a particular stock. A higher-quality stock possesses traits associated with upside potential and reduced downside risk. Backtesting of the Quality Grade shows that stocks with higher grades, on average, outperformed stocks with lower grades over the period of 1998 through 2019.

Stocks receive better grades (higher scores) for having higher scores for the quality subcomponents and worse grades (lower scores) for lower scores for the subcomponents.

Zurn Elkay Water Solutions Corporation has a Quality Score of 94, which is Very Strong. Pentair plc has a Quality Score of 91, which is Very Strong.

The Quality Grade Winner: It’s a Tie!

Looking at the Quality Grade breakdown above, both Zurn Elkay Water Solutions Corporation and Pentair plc have a grade of A. For investors who focus solely on a company’s overall quality, you will need to conduct further research into both companies to see if they are a good fit for your portfolio.

Company	Ticker	Momentum
Zurn Elkay Water Solutions Corporation	ZWS	B
Pentair plc	PNR	D

Momentum grades help to uncover stocks experiencing anomalously high rates of return; research finds that stocks with high relative levels of momentum tend to outperform, whereas those with low levels of momentum tend to continue underperforming. Momentum is based on the price change of a stock over a specified period relative to all other stocks.

Typically, AAII looks at the weighted relative strength over the trailing four quarters. The weighted four-quarter relative strength rank is the relative price change for each of the past four quarters. The most recent quarterly price change is given a weight of 40% and each of the three previous quarters are given a weighting of 20%.

Zurn Elkay Water Solutions Corporation has a Momentum Score of 72, which is Strong. Pentair plc has a Momentum Score of 30, which is Weak.

The Momentum Grade Winner: Zurn Elkay Water Solutions Corporation

Other Zurn Elkay Water Solutions Corporation and Pentair plc Grades

In addition to Value, Quality and Momentum, A+ Investor also provides grades for Growth and Estimate Revisions.

Earnings estimate revisions scores take into account the magnitude of a company’s earnings surprise in its last two reported fiscal quarters. Often, surprises beget further surprises‐or at least continued sales growth (the exact opposite is generally true, too).

Growth investing builds on the idea that stocks of companies exhibiting strong, consistent and prolonged growth outperform those of slower-growth companies. AAII measures growth through consistency of annual sales growth, five-year sales growth rankings adjusted for extreme levels, and consistency of positive annual cash from operations.

These 2 key factors, when combined with the above, provide a holistic view into a particular stock. Further, by joining A+ Investor you can see whether Zurn Elkay Water Solutions Corporation and Pentair plc pass any of our 60+ stock screens that have outperformed the market since their creation.
