STMicroelectronics N.V., Advanced Micro Devices and Inc. Stock Value Grades

Company	Ticker	Value
STMicroelectronics N.V.	STM	D
Advanced Micro Devices, Inc.	AMD	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.

STMicroelectronics N.V. has a Value Score of 30, which is Expensive. Advanced Micro Devices, Inc. has a Value Score of 3, which is Ultra Expensive.

The Value Stock Winner: No Clear Winner

Neither STMicroelectronics N.V., Advanced Micro Devices 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 STMicroelectronics N.V., Advanced Micro Devices or Inc. is the better investment when it comes to value.

STMicroelectronics N.V., Advanced Micro Devices and Inc. Growth Grades

Company	Ticker	Growth
STMicroelectronics N.V.	STM	C
Advanced Micro Devices, Inc.	AMD	C

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.

STMicroelectronics N.V. has a Growth Score of 56, which is Average. Advanced Micro Devices, Inc. has a Growth Score of 59, which is Average.

The Growth Stock Winner: No Clear Winner

Neither STMicroelectronics N.V., Advanced Micro Devices 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 STMicroelectronics N.V., Advanced Micro Devices or Inc. is the better investment when it comes to sustainable growth.

STMicroelectronics N.V., Advanced Micro Devices and Inc.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
STMicroelectronics N.V.	STM	D
Advanced Micro Devices, Inc.	AMD	C

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.

STMicroelectronics N.V. has a Earnings Estimate Score of 30, which is Negative. Advanced Micro Devices, Inc. has a Earnings Estimate Score of 58, which is Neutral.

The Earnings Estimate Revisions Stock Winner: No Clear Winner

Neither STMicroelectronics N.V., Advanced Micro Devices or Inc. has an Earnings Estimate Revisions Grade that could be considered a “winner.” Investors 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 STMicroelectronics N.V., Advanced Micro Devices or Inc. is the better investment when it comes to estimate revisions.

Other STMicroelectronics N.V., Advanced Micro Devices and Inc. Grades

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

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.

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.

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 STMicroelectronics N.V., Advanced Micro Devices and Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
