Sanmina Corporation and IPG Photonics Corporation Stock Value Grades

Company	Ticker	Value
Sanmina Corporation	SANM	C
IPG Photonics Corporation	IPGP	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.

Sanmina Corporation has a Value Score of 43, which is Average. IPG Photonics Corporation has a Value Score of 17, which is Ultra Expensive.

The Value Stock Winner: No Clear Winner

Neither Sanmina Corporation or IPG Photonics Corporation 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 Sanmina Corporation or IPG Photonics Corporation is the better investment when it comes to value.

Sanmina Corporation and IPG Photonics Corporation’s Quality Grades

Company	Ticker	Quality
Sanmina Corporation	SANM	C
IPG Photonics Corporation	IPGP	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.

Sanmina Corporation has a Quality Score of 47, which is Average. IPG Photonics Corporation has a Quality Score of 69, which is Strong.

The Quality Grade Winner: IPG Photonics Corporation

As you can clearly see from the Quality Grade breakdown above, IPG Photonics Corporation has a better overall quality grade than Sanmina Corporation. For investors who are looking for companies with higher quality than others in the same industry, IPG Photonics Corporation could be a good stock to add to their portfolios. However, it’s important for investors to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Sanmina Corporation and IPG Photonics Corporation’s Momentum Grades

Company	Ticker	Momentum
Sanmina Corporation	SANM	B
IPG Photonics Corporation	IPGP	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%.

Sanmina Corporation has a Momentum Score of 72, which is Strong. IPG Photonics Corporation has a Momentum Score of 28, which is Weak.

The Momentum Grade Winner: Sanmina Corporation

As you can clearly see from the Momentum Grade breakdown above, Sanmina Corporation is considered to have stronger momentum compared to IPG Photonics Corporation. For those specifically looking for companies that have stronger momentum compared to other companies in the same industry, Sanmina Corporation 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.

Other Sanmina Corporation and IPG Photonics Corporation Grades

In addition to Momentum, Quality and Value, 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 Sanmina Corporation and IPG Photonics Corporation pass any of our 60+ stock screens that have outperformed the market since their creation.
