Relay Therapeutics, Inc., Xencor and Inc. Stock Value Grades

Company	Ticker	Value
Relay Therapeutics, Inc.	RLAY	F
Xencor, Inc.	XNCR	F

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.

Relay Therapeutics, Inc. has a Value Score of 4, which is Ultra Expensive. Xencor, Inc. has a Value Score of 12, which is Ultra Expensive.

The Value Stock Winner: No Clear Winner

Neither Relay Therapeutics, Inc., Xencor or Inc. 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. It’s important to look at a wide range of financial metrics in order to determine if Relay Therapeutics, Inc., Xencor or Inc. is the better investment when it comes to value.

Relay Therapeutics, Inc., Xencor and Inc. Growth Grades

Company	Ticker	Growth
Relay Therapeutics, Inc.	RLAY	F
Xencor, Inc.	XNCR	F

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.

Relay Therapeutics, Inc. has a Growth Score of 3, which is Very Weak. Xencor, Inc. has a Growth Score of 9, which is Very Weak.

The Growth Stock Winner: No Clear Winner

Neither Relay Therapeutics, Inc., Xencor or Inc. has a high enough Growth 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 portfolios. It’s important to look at a wide range of financial metrics in order to determine if Relay Therapeutics, Inc., Xencor or Inc. is the better investment when it comes to sustainable growth.

Relay Therapeutics, Inc., Xencor and Inc.’s Quality Grades

Company	Ticker	Quality
Relay Therapeutics, Inc.	RLAY	D
Xencor, Inc.	XNCR	F

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.

Relay Therapeutics, Inc. has a Quality Score of 29, which is Weak. Xencor, Inc. has a Quality Score of 11, which is Very Weak.

The Quality Stock Winner: No Clear Winner

Neither Relay Therapeutics, Inc., Xencor or Inc. has a high enough Quality 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 portfolios. It’s important to look at a wide range of financial metrics in order to determine if Relay Therapeutics, Inc., Xencor or Inc. is the better investment when it comes to quality.

Other Relay Therapeutics, Inc., Xencor and Inc. Grades

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

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.

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).

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 Relay Therapeutics, Inc., Xencor and Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
