ACADIA Pharmaceuticals Inc., Halozyme Therapeutics and Inc. Stock Value Grades

Company	Ticker	Value
ACADIA Pharmaceuticals Inc.	ACAD	D
Halozyme Therapeutics, Inc.	HALO	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.

ACADIA Pharmaceuticals Inc. has a Value Score of 26, which is Expensive. Halozyme Therapeutics, Inc. has a Value Score of 36, which is Expensive.

The Value Stock Winner: No Clear Winner

Neither ACADIA Pharmaceuticals Inc., Halozyme Therapeutics 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 ACADIA Pharmaceuticals Inc., Halozyme Therapeutics or Inc. is the better investment when it comes to value.

ACADIA Pharmaceuticals Inc., Halozyme Therapeutics and Inc.’s Quality Grades

Company	Ticker	Quality
ACADIA Pharmaceuticals Inc.	ACAD	B
Halozyme Therapeutics, Inc.	HALO	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.

ACADIA Pharmaceuticals Inc. has a Quality Score of 72, which is Strong. Halozyme Therapeutics, Inc. has a Quality Score of 95, which is Very Strong.

The Quality Grade Winner: Halozyme Therapeutics, Inc.

As you can clearly see from the Quality Grade breakdown above, Halozyme Therapeutics, Inc. has a better overall quality grade than ACADIA Pharmaceuticals Inc.. For investors who are looking for companies with higher quality than others in the same industry, Halozyme Therapeutics, Inc. could be a good stock to add to their portfolios. 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., Halozyme Therapeutics and Inc.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
ACADIA Pharmaceuticals Inc.	ACAD	F
Halozyme Therapeutics, Inc.	HALO	D

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 17, which is Very Negative. Halozyme Therapeutics, Inc. has a Earnings Estimate Score of 33, which is Negative.

The Earnings Estimate Revisions Stock Winner: No Clear Winner

Other ACADIA Pharmaceuticals Inc., Halozyme Therapeutics and Inc. Grades

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

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.
