Momentum is based on the price change of a stock over a specified period relative to all other stocks.

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%.

Enphase Energy, Inc. has a Momentum Score of 9, which is Very Weak. Photronics, Inc. has a Momentum Score of 88, which is Very Strong.

Company	Ticker	Earnings Estimate

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.

Enphase Energy, Inc. has a Earnings Estimate Score of 70, which is Positive. Photronics, Inc. has a Earnings Estimate Score of 90, which is Very Positive.

Other Enphase Energy, Inc., Photronics and Inc. Grades

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

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 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 Enphase Energy, Inc., Photronics and Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
