AeroVironment, Inc. and Moog Inc. Stock Value Grades

Company	Ticker	Value
AeroVironment, Inc.	AVAV	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.

AeroVironment, Inc. has a Value Score of 17, which is Ultra Expensive. Moog Inc. has a Value Score of 22, which is Expensive.

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

Company	Ticker	Earnings Estimate

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.

AeroVironment, Inc. has a Earnings Estimate Score of 36, which is Negative. Moog Inc. has a Earnings Estimate Score of 82, which is Very Positive.

Other AeroVironment, Inc. and Moog Inc. Grades
