Sensata Technologies Holding plc, Littelfuse and Inc. Stock Value Grades

Company	Ticker	Value
Sensata Technologies Holding plc	ST	C

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.

Sensata Technologies Holding plc has a Value Score of 46, which is Average. Littelfuse, Inc. has a Value Score of 20, which is Ultra Expensive.

The Value Stock Winner: No Clear Winner

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%.

Company	Ticker	Earnings Estimate
Sensata Technologies Holding plc	ST	C
Littelfuse, Inc.	LFUS	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.

Sensata Technologies Holding plc has a Earnings Estimate Score of 56, which is Neutral. Littelfuse, Inc. has a Earnings Estimate Score of 80, which is Positive.

The Earnings Estimate Revisions Grade Winner: Littelfuse, Inc.

Other Sensata Technologies Holding plc, Littelfuse and Inc. Grades

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