Lam Research Corporation, Marvell Technology and Inc. Stock Value Grades

Company	Ticker	Value
Lam Research Corporation	LRCX	F
Marvell Technology, Inc.	MRVL	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.

Lam Research Corporation has a Value Score of 8, which is Ultra Expensive. Marvell Technology, Inc. has a Value Score of 3, which is Ultra Expensive.

The Value Stock Winner: No Clear Winner

Neither Lam Research Corporation, Marvell Technology 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 Lam Research Corporation, Marvell Technology or Inc. is the better investment when it comes to value.

Lam Research Corporation, Marvell Technology and Inc.’s Quality Grades

Company	Ticker	Quality
Lam Research Corporation	LRCX	A
Marvell Technology, Inc.	MRVL	NA

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.

Lam Research Corporation has a Quality Score of 99, which is Very Strong. Marvell Technology, Inc. does not have a meaningful Quality Score.

The Quality Stock Winner: Undetermined

If you are strictly an investor who focuses on finding quality stocks, you may want to add Lam Research Corporation to your watch list. However, because only one of the companies in this comparison has a valid Quality Grade, we cannot name it a clear winner. Evaluation of the other grades for both companies is necessary in order to understand which stock is the better investment based on AAII’s proprietary scores and analysis.

Lam Research Corporation, Marvell Technology and Inc.’s Momentum Grades

Company	Ticker	Momentum
Lam Research Corporation	LRCX	A
Marvell Technology, Inc.	MRVL	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%.

Lam Research Corporation has a Momentum Score of 94, which is Very Strong. Marvell Technology, Inc. has a Momentum Score of 94, which is Very Strong.

The Momentum Grade Winner: It’s a Tie!

Looking at the Momentum Grade breakdown above, both Lam Research Corporation, Marvell Technology and Inc. 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.

Other Lam Research Corporation, Marvell Technology and Inc. Grades

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

Earnings estimate revisions scores take into account the magnitude of a company’s earnings surprise in its last two reported fiscal quarters. Often, surprises beget further surprises‐or at least continued sales growth (the exact opposite is generally true, too).

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.

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 Lam Research Corporation, Marvell Technology and Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
