ASE Technology Holding Co., Ltd. and Microchip Technology Incorporated’s Quality Grades

Company	Ticker	Quality
ASE Technology Holding Co., Ltd.	ASX	C
Microchip Technology Incorporated	MCHP	C

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.

ASE Technology Holding Co., Ltd. has a Quality Score of 53, which is Average. Microchip Technology Incorporated has a Quality Score of 57, which is Average.

The Quality Stock Winner: No Clear Winner

Neither ASE Technology Holding Co., Ltd. or Microchip Technology Incorporated has a high enough Quality 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 ASE Technology Holding Co., Ltd. or Microchip Technology Incorporated is the better investment when it comes to quality.

ASE Technology Holding Co., Ltd. and Microchip Technology Incorporated’s Momentum Grades

Company	Ticker	Momentum
ASE Technology Holding Co., Ltd.	ASX	A
Microchip Technology Incorporated	MCHP	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%.

ASE Technology Holding Co., Ltd. has a Momentum Score of 94, which is Very Strong. Microchip Technology Incorporated has a Momentum Score of 82, which is Very Strong.

The Momentum Grade Winner: It’s a Tie!

Looking at the Momentum Grade breakdown above, both ASE Technology Holding Co., Ltd. and Microchip Technology Incorporated have a grade of A. For those who focus solely on a company’s momentum, further research will need to be conducted into both companies to see if they fit your individual needs as an investor.

ASE Technology Holding Co., Ltd. and Microchip Technology Incorporated’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
ASE Technology Holding Co., Ltd.	ASX	B
Microchip Technology Incorporated	MCHP	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.

ASE Technology Holding Co., Ltd. has a Earnings Estimate Score of 63, which is Positive. Microchip Technology Incorporated has a Earnings Estimate Score of 49, which is Neutral.

The Earnings Estimate Revisions Grade Winner: ASE Technology Holding Co., Ltd.

As you can clearly see from the Earnings Estimate Revisions Grade breakdown above, ASE Technology Holding Co., Ltd. has a better Earnings Estimate Revisions Grade than Microchip Technology Incorporated. For those who are specifically looking for companies with better short-term prospects when compared to other companies in the same industry, ASE Technology Holding Co., Ltd. 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 ASE Technology Holding Co., Ltd. and Microchip Technology Incorporated Grades

In addition to Estimate Revisions, Momentum and Quality, 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 ASE Technology Holding Co., Ltd. and Microchip Technology Incorporated pass any of our 60+ stock screens that have outperformed the market since their creation.
