Canadian Solar Inc. and Nova Ltd. Stock Value Grades

Company	Ticker	Value
Canadian Solar Inc.	CSIQ	B
Nova Ltd.	NVMI	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.

Canadian Solar Inc. has a Value Score of 62, which is Value. Nova Ltd. has a Value Score of 8, which is Ultra Expensive.

The Value Stock Winner: Canadian Solar Inc.

As you can clearly see from the Value Grade breakdown above, Canadian Solar Inc. is considered to have better value than Nova Ltd..

Canadian Solar Inc. and Nova Ltd. Growth Grades

Company	Ticker	Growth
Canadian Solar Inc.	CSIQ	C
Nova Ltd.	NVMI	B

The foundation of growth investing is seeking out stocks of companies exhibiting strong, consistent and prolonged growth that is expected to continue into the future.

In order to compute the growth score and assign it a letter grade, the percentile ranks for each of three components‐consistency of annual sales growth, five-year sales growth rankings adjusted for extreme levels, and consistency of positive annual cash from operations‐must be determined. These three rank figures are added together, and the sum is ranked against the entire stock universe to arrive at a company’s Growth Score to create an equal distribution of grades.

The companies in the bottom 20% of the stock universe receive Growth Grades of F, considered to be very weak, while those in the top 20% receive A grades, which are considered very strong.

Canadian Solar Inc. has a Growth Score of 48, which is Average. Nova Ltd. has a Growth Score of 62, which is Strong.

The Growth Grade Winner: Nova Ltd.

As you can clearly see from the Growth Grade breakdown above, Nova Ltd. has a more attractive growth grade than Canadian Solar Inc..

Canadian Solar Inc. and Nova Ltd.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
Canadian Solar Inc.	CSIQ	C
Nova Ltd.	NVMI	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.

Canadian Solar Inc. has a Earnings Estimate Score of 57, which is Neutral. Nova Ltd. has a Earnings Estimate Score of 50, which is Neutral.

The Earnings Estimate Revisions Stock Winner: No Clear Winner

It’s important to look at a wide range of financial metrics in order to determine if Canadian Solar Inc. or Nova Ltd. is the better investment when it comes to estimate revisions.

Other Canadian Solar Inc. and Nova Ltd. Grades

Momentum grades help 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.

AAII’s A+ Investor Quality Grade comes from the ranking of key metrics.
