ACADIA Pharmaceuticals Inc., Xencor and Inc. Stock Value Grades

Company	Ticker	Value
ACADIA Pharmaceuticals Inc.	ACAD	D
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.

ACADIA Pharmaceuticals Inc. has a Value Score of 21, which is Expensive. Xencor, Inc. has a Value Score of 12, which is Ultra Expensive.

The Value Stock Winner: No Clear Winner

Xencor, Inc.	XNCR	A

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%.

ACADIA Pharmaceuticals Inc. has a Momentum Score of 80, which is Strong. Xencor, Inc. has a Momentum Score of 99, which is Very Strong.

However, it’s important for investors to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

ACADIA Pharmaceuticals Inc., Xencor and Inc.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
ACADIA Pharmaceuticals Inc.	ACAD	B
Xencor, Inc.	XNCR	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.

ACADIA Pharmaceuticals Inc. has a Earnings Estimate Score of 68, which is Positive. Xencor, Inc. has a Earnings Estimate Score of 67, which is Positive.

The Earnings Estimate Revisions Grade Winner: It’s a Tie!

Looking at the Earnings Estimate Revisions Grade breakdown above, both ACADIA Pharmaceuticals Inc., Xencor and Inc. have a grade of B. For those focusing solely on a company’s estimate revisions, other financial metrics will need to be evaluated to determine whether ACADIA Pharmaceuticals Inc., Xencor or Inc. is a better fit.

Other ACADIA Pharmaceuticals Inc., Xencor and Inc. Grades

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

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.

AAII’s A+ Investor Quality Grade comes from the ranking of key metrics. Specifically, the quality grade is the percentile rank of the composite 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 F-Score.
