Advanced Micro Devices, Inc. and ON Semiconductor Corporation Stock Value Grades

Company	Ticker	Value
Advanced Micro Devices, Inc.	AMD	F
ON Semiconductor Corporation	ON	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.

Advanced Micro Devices, Inc. has a Value Score of 3, which is Ultra Expensive. ON Semiconductor Corporation has a Value Score of 28, which is Expensive.

The Value Stock Winner: No Clear Winner

Neither Advanced Micro Devices, Inc. or ON Semiconductor Corporation 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 Advanced Micro Devices, Inc. or ON Semiconductor Corporation is the better investment when it comes to value.

Advanced Micro Devices, Inc. and ON Semiconductor Corporation’s Momentum Grades

Company	Ticker	Momentum
Advanced Micro Devices, Inc.	AMD	A
ON Semiconductor Corporation	ON	B

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%.

Advanced Micro Devices, Inc. has a Momentum Score of 95, which is Very Strong. ON Semiconductor Corporation has a Momentum Score of 67, which is Strong.

The Momentum Grade Winner: Advanced Micro Devices, Inc.

As you can clearly see from the Momentum Grade breakdown above, Advanced Micro Devices, Inc. is considered to have stronger momentum compared to ON Semiconductor Corporation. For those specifically looking for companies that have stronger momentum compared to other companies in the same industry, Advanced Micro Devices, Inc. could be a good stock to invest in. However, it’s important for investors to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Advanced Micro Devices, Inc. and ON Semiconductor Corporation’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
Advanced Micro Devices, Inc.	AMD	C
ON Semiconductor Corporation	ON	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.

Advanced Micro Devices, Inc. has a Earnings Estimate Score of 58, which is Neutral. ON Semiconductor Corporation has a Earnings Estimate Score of 58, which is Neutral.

The Earnings Estimate Revisions Stock Winner: No Clear Winner

Neither Advanced Micro Devices, Inc. or ON Semiconductor Corporation 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 Advanced Micro Devices, Inc. or ON Semiconductor Corporation is the better investment when it comes to estimate revisions.

Other Advanced Micro Devices, Inc. and ON Semiconductor Corporation Grades

In addition to Momentum, Value and Estimate Revisions, 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.

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 Advanced Micro Devices, Inc. and ON Semiconductor Corporation pass any of our 60+ stock screens that have outperformed the market since their creation.
