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.

Regeneron Pharmaceuticals, Inc. has a Growth Score of 82, which is Very Strong. Sarepta Therapeutics, Inc. has a Growth Score of 29, which is Weak.

The Growth Grade Winner: Regeneron Pharmaceuticals, Inc.

Regeneron Pharmaceuticals, Inc., Sarepta Therapeutics and Inc.’s Quality Grades

Company Ticker Quality
Regeneron Pharmaceuticals, Inc. REGN A
Sarepta Therapeutics, Inc. SRPT D

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.

Regeneron Pharmaceuticals, Inc. has a Quality Score of 81, which is Very Strong. Sarepta Therapeutics, Inc. has a Quality Score of 36, which is Weak.

The Quality Grade Winner: Regeneron Pharmaceuticals, Inc.

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%.

Regeneron Pharmaceuticals, Inc. has a Momentum Score of 87, which is Very Strong. Sarepta Therapeutics, Inc. has a Momentum Score of 81, which is Very Strong.

Other Regeneron Pharmaceuticals, Inc., Sarepta Therapeutics and Inc. Grades

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

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.
