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.

National Energy Services Reunited Corp. has a Value Score of 29, which is Expensive. Oceaneering International, Inc. has a Value Score of 69, which is Value.

The Value Stock Winner: Oceaneering International, Inc.

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.

National Energy Services Reunited Corp., Oceaneering International and Inc.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
National Energy Services Reunited Corp.	NESR	C
Oceaneering International, Inc.	OII	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.

National Energy Services Reunited Corp. has a Earnings Estimate Score of 49, which is Neutral. Oceaneering International, Inc. has a Earnings Estimate Score of 47, which is Neutral.

Other National Energy Services Reunited Corp., Oceaneering International and Inc. Grades

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

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.
