STMicroelectronics N.V. and Microchip Technology Incorporated’s Quality Grades

Company	Ticker	Quality
STMicroelectronics N.V.	STM	B
Microchip Technology Incorporated	MCHP	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.

STMicroelectronics N.V. has a Quality Score of 63, which is Strong. Microchip Technology Incorporated has a Quality Score of 79, which is Strong.

The Quality Grade Winner: It’s a Tie!

Looking at the Quality Grade breakdown above, both STMicroelectronics N.V. and Microchip Technology Incorporated have a grade of B. For investors who focus solely on a company’s overall quality, you will need to conduct further research into both companies to see if they are a good fit for your portfolio. As a good rule of thumb, you should always analyze multiple factors based on a wide range of metrics before choosing a company to invest in.

STMicroelectronics N.V. and Microchip Technology Incorporated’s Momentum Grades

Company	Ticker	Momentum
STMicroelectronics N.V.	STM	A
Microchip Technology Incorporated	MCHP	D

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%.

STMicroelectronics N.V. has a Momentum Score of 86, which is Very Strong. Microchip Technology Incorporated has a Momentum Score of 38, which is Weak.

The Momentum Grade Winner: STMicroelectronics N.V.

As you can clearly see from the Momentum Grade breakdown above, STMicroelectronics N.V. is considered to have stronger momentum compared to Microchip Technology Incorporated. For those specifically looking for companies that have stronger momentum compared to other companies in the same industry, STMicroelectronics N.V. 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.

STMicroelectronics N.V. and Microchip Technology Incorporated’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
STMicroelectronics N.V.	STM	D
Microchip Technology Incorporated	MCHP	A

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 40, which is Negative. Microchip Technology Incorporated has a Earnings Estimate Score of 87, which is Very Positive.

The Earnings Estimate Revisions Grade Winner: Microchip Technology Incorporated

As you can clearly see from the Earnings Estimate Revisions Grade breakdown above, Microchip Technology Incorporated has a better Earnings Estimate Revisions Grade than STMicroelectronics N.V.. For those who are specifically looking for companies with better short-term prospects when compared to other companies in the same industry, Microchip Technology Incorporated could be a good stock to invest in. However, it’s important to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Other STMicroelectronics N.V. and Microchip Technology Incorporated Grades

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

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.

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 STMicroelectronics N.V. and Microchip Technology Incorporated pass any of our 60+ stock screens that have outperformed the market since their creation.
