Mettler-Toledo International Inc., Avantor and Inc. Stock Value Grades

Company Ticker Value
Mettler-Toledo International Inc. MTD D
Avantor, Inc. AVTR C

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.

Mettler-Toledo International Inc. has a Value Score of 22, which is Expensive. Avantor, Inc. has a Value Score of 49, which is Average.

The Value Stock Winner: No Clear Winner

Neither Mettler-Toledo International Inc., Avantor or Inc. 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. It’s important to look at a wide range of financial metrics in order to determine if Mettler-Toledo International Inc., Avantor or Inc. is the better investment when it comes to value.

Mettler-Toledo International Inc., Avantor and Inc.’s Quality Grades

Company Ticker Quality
Mettler-Toledo International Inc. MTD A
Avantor, Inc. AVTR B

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.

Mettler-Toledo International Inc. has a Quality Score of 99, which is Very Strong. Avantor, Inc. has a Quality Score of 76, which is Strong.

The Quality Grade Winner: Mettler-Toledo International Inc.

As you can clearly see from the Quality Grade breakdown above, Mettler-Toledo International Inc. has a better overall quality grade than Avantor, Inc.. For investors who are looking for companies with higher quality than others in the same industry, Mettler-Toledo International Inc. could be a good stock to add to their portfolios.

Mettler-Toledo International Inc., Avantor and Inc.’s Estimate Revisions Grades

Company Ticker Earnings Estimate
Mettler-Toledo International Inc. MTD B
Avantor, Inc. AVTR B

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.

Mettler-Toledo International Inc. has a Earnings Estimate Score of 64, which is Positive. Avantor, Inc. has a Earnings Estimate Score of 70, which is Positive.

The Earnings Estimate Revisions Grade Winner: It’s a Tie!

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.
