Semtech Corporation and Synaptics Incorporated Stock Value Grades

Company	Ticker	Value
Semtech Corporation	SMTC	F
Synaptics Incorporated	SYNA	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.

Semtech Corporation has a Value Score of 2, which is Ultra Expensive. Synaptics Incorporated has a Value Score of 23, which is Expensive.

The Value Stock Winner: No Clear Winner

Neither Semtech Corporation or Synaptics Incorporated 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 Semtech Corporation or Synaptics Incorporated is the better investment when it comes to value.

Semtech Corporation and Synaptics Incorporated’s Momentum Grades

Company	Ticker	Momentum
Semtech Corporation	SMTC	A
Synaptics Incorporated	SYNA	C

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%.

Semtech Corporation has a Momentum Score of 87, which is Very Strong. Synaptics Incorporated has a Momentum Score of 59, which is Average.

Company	Ticker	Earnings Estimate
Semtech Corporation	SMTC	A
Synaptics Incorporated	SYNA	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.

Semtech Corporation has a Earnings Estimate Score of 95, which is Very Positive. Synaptics Incorporated has a Earnings Estimate Score of 47, which is Neutral.

The Earnings Estimate Revisions Grade Winner: Semtech Corporation

For those who are specifically looking for companies with better short-term prospects when compared to other companies in the same industry, Semtech 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 Semtech Corporation and Synaptics Incorporated 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. Further, by joining A+ Investor you can see whether Semtech Corporation and Synaptics Incorporated pass any of our 60+ stock screens that have outperformed the market since their creation.
