Regal Rexnord Corporation, Rockwell Automation and Inc. Growth Grades

Company	Ticker	Growth
Regal Rexnord Corporation	RRX	B

The foundation of growth investing is seeking out stocks of companies exhibiting strong, consistent and prolonged growth that is expected to continue into the future.

In order to compute the growth score and assign it a letter grade, the percentile ranks for each of three components‐consistency of annual sales growth, five-year sales growth rankings adjusted for extreme levels, and consistency of positive annual cash from operations‐must be determined. These three rank figures are added together, and the sum is ranked against the entire stock universe to arrive at a company’s Growth Score to create an equal distribution of grades.

The companies in the bottom 20% of the stock universe receive Growth Grades of F, considered to be very weak, while those in the top 20% receive A grades, which are considered very strong.

Regal Rexnord Corporation has a Growth Score of 72, which is Strong. Rockwell Automation, Inc. has a Growth Score of 97, which is Very Strong.

The Growth Grade Winner: Rockwell Automation, Inc.

Regal Rexnord Corporation, Rockwell Automation and Inc.’s Quality Grades

Company	Ticker	Quality
Regal Rexnord Corporation	RRX	A
Rockwell Automation, Inc.	ROK	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.

Regal Rexnord Corporation has a Quality Score of 83, which is Very Strong. Rockwell Automation, Inc. has a Quality Score of 96, which is Very Strong.

The Quality Grade Winner: It’s a Tie!

Regal Rexnord Corporation, Rockwell Automation and Inc.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
Regal Rexnord Corporation	RRX	D
Rockwell Automation, Inc.	ROK	B

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

Estimate revisions offer an indication of what analysts are thinking about the short-term prospects of a firm. Estimate revisions are based on the statistical significance of a firm’s last two quarterly earnings surprises and the percentage change in its consensus estimate for the current fiscal year over the past month and past three months.

Regal Rexnord Corporation has a Earnings Estimate Score of 32, which is Negative. Rockwell Automation, Inc. has a Earnings Estimate Score of 75, which is Positive.

The Earnings Estimate Revisions Grade Winner: Rockwell Automation, Inc.

As you can clearly see from the Earnings Estimate Revisions Grade breakdown above, Rockwell Automation, Inc. has a better Earnings Estimate Revisions Grade than Regal Rexnord Corporation. For those who are specifically looking for companies with better short-term prospects when compared to other companies in the same industry, Rockwell Automation, Inc. could be a good stock to invest in. However, it’s important to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Other Regal Rexnord Corporation, Rockwell Automation and Inc. Grades

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

Momentum grades help 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.

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.

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 Regal Rexnord Corporation, Rockwell Automation and Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
