Stifel Financial Corp. and StoneX Group Inc. Stock Value Grades

Company	Ticker	Value
Stifel Financial Corp.	SF	C
StoneX Group Inc.	SNEX	B

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.

Stifel Financial Corp. has a Value Score of 41, which is Average. StoneX Group Inc. has a Value Score of 71, which is Value.

The Value Stock Winner: StoneX Group Inc.

As you can clearly see from the Value Grade breakdown above, StoneX Group Inc. is considered to have better value than Stifel Financial Corp.. For investors who focus solely on a company’s valuation, StoneX Group Inc. could be a good stock to add to their portfolio. However, it’s important for investors to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Stifel Financial Corp. and StoneX Group Inc.’s Quality Grades

Company	Ticker	Quality
Stifel Financial Corp.	SF	D
StoneX Group Inc.	SNEX	D

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.

Stifel Financial Corp. has a Quality Score of 33, which is Weak. StoneX Group Inc. has a Quality Score of 36, which is Weak.

The Quality Stock Winner: No Clear Winner

Neither Stifel Financial Corp. or StoneX Group Inc. has a high enough Quality 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 portfolios. It’s important to look at a wide range of financial metrics in order to determine if Stifel Financial Corp. or StoneX Group Inc. is the better investment when it comes to quality.

Company	Ticker	Earnings Estimate
Stifel Financial Corp.	SF	C
StoneX Group Inc.	SNEX	A

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.

Stifel Financial Corp. has a Earnings Estimate Score of 50, which is Neutral. StoneX Group Inc. has a Earnings Estimate Score of 83, which is Very Positive.

The Earnings Estimate Revisions Grade Winner: StoneX Group Inc.

For those who are specifically looking for companies with better short-term prospects when compared to other companies in the same industry, StoneX Group Inc. could be a good stock to invest in. However, it’s important to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Other Stifel Financial Corp. and StoneX Group Inc. Grades

In addition to Value, Quality and Estimate Revisions, 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.
