Himax Technologies, Inc., Aehr Test Systems and Inc. Stock Value Grades

Company	Ticker	Value
Himax Technologies, Inc.	HIMX	D
Aehr Test Systems, Inc.	AEHR	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.

Himax Technologies, Inc. has a Value Score of 21, which is Expensive. Aehr Test Systems, Inc. has a Value Score of 3, which is Ultra Expensive.

The Value Stock Winner: No Clear Winner

Neither Himax Technologies, Inc., Aehr Test Systems 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 Himax Technologies, Inc., Aehr Test Systems or Inc. is the better investment when it comes to value.

Himax Technologies, Inc., Aehr Test Systems and Inc.’s Momentum Grades

Company	Ticker	Momentum
Himax Technologies, Inc.	HIMX	A
Aehr Test Systems, Inc.	AEHR	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%.

Himax Technologies, Inc. has a Momentum Score of 87, which is Very Strong. Aehr Test Systems, Inc. has a Momentum Score of 100, which is Very Strong.

The Momentum Grade Winner: It’s a Tie!

Looking at the Momentum Grade breakdown above, both Himax Technologies, Inc., Aehr Test Systems 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.

Himax Technologies, Inc., Aehr Test Systems and Inc.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
Himax Technologies, Inc.	HIMX	D
Aehr Test Systems, Inc.	AEHR	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.

Himax Technologies, Inc. has a Earnings Estimate Score of 37, which is Negative. Aehr Test Systems, Inc. has a Earnings Estimate Score of 67, which is Positive.

The Earnings Estimate Revisions Grade Winner: Aehr Test Systems, Inc.

As you can clearly see from the Earnings Estimate Revisions Grade breakdown above, Aehr Test Systems, Inc. has a better Earnings Estimate Revisions Grade than Himax Technologies, Inc.. For those who are specifically looking for companies with better short-term prospects when compared to other companies in the same industry, Aehr Test Systems, Inc. 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 Himax Technologies, Inc., Aehr Test Systems and Inc. Grades

In addition to Value, Estimate Revisions and Momentum, 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. Further, by joining A+ Investor you can see whether Himax Technologies, Inc., Aehr Test Systems and Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
