Tango Therapeutics, Inc. and ACADIA Pharmaceuticals Inc. Growth Grades

Company	Ticker	Growth
Tango Therapeutics, Inc.	TNGX	F
ACADIA Pharmaceuticals Inc.	ACAD	D

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.

Tango Therapeutics, Inc. has a Growth Score of 19, which is Very Weak. ACADIA Pharmaceuticals Inc. has a Growth Score of 37, which is Weak.

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

Company	Ticker	Quality
Tango Therapeutics, Inc.	TNGX	D
ACADIA Pharmaceuticals Inc.	ACAD	B

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.

Tango Therapeutics, Inc. has a Quality Score of 25, which is Weak. ACADIA Pharmaceuticals Inc. has a Quality Score of 72, which is Strong.

The Quality Grade Winner: ACADIA Pharmaceuticals Inc.

Company	Ticker	Momentum
Tango Therapeutics, Inc.	TNGX	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%.

Tango Therapeutics, Inc. has a Momentum Score of 99, which is Very Strong. ACADIA Pharmaceuticals Inc. has a Momentum Score of 32, which is Weak.

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

In addition to Momentum, Quality and Growth, 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. Further, by joining A+ Investor you can see whether Tango Therapeutics, Inc. and ACADIA Pharmaceuticals Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
