Marvell Technology, Inc. and Taiwan Semiconductor Manufacturing Company Limited Stock Value Grades

Company	Ticker	Value
Marvell Technology, Inc.	MRVL	F
Taiwan Semiconductor Manufacturing Company Limited	TSM	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.

Marvell Technology, Inc. has a Value Score of 2, which is Ultra Expensive. Taiwan Semiconductor Manufacturing Company Limited has a Value Score of 31, which is Expensive.

The Value Stock Winner: No Clear Winner

Neither Marvell Technology, Inc. or Taiwan Semiconductor Manufacturing Company Limited 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 Marvell Technology, Inc. or Taiwan Semiconductor Manufacturing Company Limited is the better investment when it comes to value.

Marvell Technology, Inc. and Taiwan Semiconductor Manufacturing Company Limited’s Momentum Grades

Company	Ticker	Momentum
Marvell Technology, Inc.	MRVL	A
Taiwan Semiconductor Manufacturing Company Limited	TSM	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%.

Marvell Technology, Inc. has a Momentum Score of 97, which is Very Strong. Taiwan Semiconductor Manufacturing Company Limited has a Momentum Score of 77, which is Strong.

The Momentum Grade Winner: Marvell Technology, Inc.

As you can clearly see from the Momentum Grade breakdown above, Marvell Technology, Inc. is considered to have stronger momentum compared to Taiwan Semiconductor Manufacturing Company Limited. For those specifically looking for companies that have stronger momentum compared to other companies in the same industry, Marvell Technology, 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.

Marvell Technology, Inc. and Taiwan Semiconductor Manufacturing Company Limited’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
Marvell Technology, Inc.	MRVL	C
Taiwan Semiconductor Manufacturing Company Limited	TSM	B

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.

Marvell Technology, Inc. has a Earnings Estimate Score of 55, which is Neutral. Taiwan Semiconductor Manufacturing Company Limited has a Earnings Estimate Score of 64, which is Positive.

The Earnings Estimate Revisions Grade Winner: Taiwan Semiconductor Manufacturing Company Limited

As you can clearly see from the Earnings Estimate Revisions Grade breakdown above, Taiwan Semiconductor Manufacturing Company Limited has a better Earnings Estimate Revisions Grade than Marvell Technology, Inc.. For those who are specifically looking for companies with better short-term prospects when compared to other companies in the same industry, Taiwan Semiconductor Manufacturing Company Limited 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 Marvell Technology, Inc. and Taiwan Semiconductor Manufacturing Company Limited Grades

In addition to Estimate Revisions, Momentum and Value, 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.
