Lam Research Corporation, ASE Technology Holding Co. and Ltd. Stock Value Grades

Company	Ticker	Value
Lam Research Corporation	LRCX	F
ASE Technology Holding Co., Ltd.	ASX	C

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.

Lam Research Corporation has a Value Score of 7, which is Ultra Expensive. ASE Technology Holding Co., Ltd. has a Value Score of 45, which is Average.

The Value Stock Winner: No Clear Winner

Neither Lam Research Corporation, ASE Technology Holding Co. or Ltd. 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.

Lam Research Corporation, ASE Technology Holding Co. and Ltd. Growth Grades

Company	Ticker	Growth
Lam Research Corporation	LRCX	A
ASE Technology Holding Co., Ltd.	ASX	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.

Lam Research Corporation has a Growth Score of 95, which is Very Strong. ASE Technology Holding Co., Ltd. has a Growth Score of 56, which is Average.

The Growth Grade Winner: Lam Research Corporation

As you can clearly see from the Growth Grade breakdown above, Lam Research Corporation has a more attractive growth grade than ASE Technology Holding Co., Ltd.. For investors who focus solely on how a company is growing relative to other companies in the same industry, Lam Research Corporation could be a good stock to add to their portfolio. However, it’s important for investors to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Lam Research Corporation, ASE Technology Holding Co. and Ltd.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
Lam Research Corporation	LRCX	B
ASE Technology Holding Co., Ltd.	ASX	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.

Lam Research Corporation has a Earnings Estimate Score of 67, which is Positive. ASE Technology Holding Co., Ltd. has a Earnings Estimate Score of 51, which is Neutral.

The Earnings Estimate Revisions Grade Winner: Lam Research Corporation

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

In addition to Growth, Value and Estimate Revisions, 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.
