AMETEK, Inc., Nidec Corporation and Nidec Corporation Stock Value Grades

Company	Ticker	Value
AMETEK, Inc.	AME	F
Nidec Corporation	NJDCY	na
Nidec Corporation	NJDCY	na

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.

AMETEK, Inc. has a Value Score of 16, which is Ultra Expensive. Nidec Corporation does not have a meaningful Value Score. Nidec Corporation does not have a meaningful Value Score.

The Value Stock Winner: No Clear Winner

Neither AMETEK, Inc., Nidec Corporation or Nidec Corporation has a high enough value grade to be considered a “winner.” Investors who are considering these companies should do additional due diligence and research to see if either could be a good addition to their portfolio.

AMETEK, Inc., Nidec Corporation and Nidec Corporation’s Quality Grades

Company	Ticker	Quality
AMETEK, Inc.	AME	A
Nidec Corporation	NJDCY	C
Nidec Corporation	NJDCY	C

Like the Value Grade, AAII’s A+ Investor Quality Grade comes from the percentile rank of key metrics. Specifically, the Quality Score is the percentile rank of the average of the percentile ranks 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 the F-Score.

The score is variable, meaning it can consider all eight measures or, should any of the eight measures not be valid, the remaining measures that are valid. To be assigned a Quality Score, stocks must have a valid (non-null) measure and corresponding ranking for at least four of the eight quality measures.

The Quality Score is used to assess the underlying “quality” of a particular stock. A higher-quality stock possesses traits associated with upside potential and reduced downside risk. Backtesting of the Quality Grade shows that stocks with higher grades, on average, outperformed stocks with lower grades over the period of 1998 through 2019.

Stocks receive better grades (higher scores) for having higher scores for the quality subcomponents and worse grades (lower scores) for lower scores for the subcomponents.

AMETEK, Inc. has a Quality Score of 91, which is Very Strong. Nidec Corporation has a Quality Score of 58, which is Average. Nidec Corporation has a Quality Score of 58, which is Average.

Company	Ticker	Earnings Estimate
AMETEK, Inc.	AME	B
Nidec Corporation	NJDCY	na
Nidec Corporation	NJDCY	na

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.

AMETEK, Inc. has a Earnings Estimate Score of 67, which is Positive. Nidec Corporation does not have a meaningful Earnings Estimate Score. Nidec Corporation does not have a meaningful Earnings Estimate Score.

However, because only one of the companies in our comparison has a valid Earnings Estimate Revisions Grade, we cannot call it a clear winner. Evaluation of the other grades for both companies is necessary in order to understand which stock is the better investment based on AAII’s proprietary scores and analysis.

Other AMETEK, Inc., Nidec Corporation and Nidec Corporation Grades

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

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.

Growth investing builds on the idea that stocks of companies exhibiting strong, consistent and prolonged growth outperform those of slower-growth companies. AAII measures growth through consistency of annual sales growth, five-year sales growth rankings adjusted for extreme levels, and consistency of positive annual cash from operations.

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 AMETEK, Inc., Nidec Corporation and Nidec Corporation pass any of our 60+ stock screens that have outperformed the market since their creation.
