Fidelity National Information Services, Inc. and StoneCo Ltd.’s Quality Grades

Company	Ticker	Quality
Fidelity National Information Services, Inc.	FIS	D
StoneCo Ltd.	STNE	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.

Fidelity National Information Services, Inc. has a Quality Score of 28, which is Weak. StoneCo Ltd. has a Quality Score of 74, which is Strong.

The Quality Grade Winner: StoneCo Ltd.

As you can clearly see from the Quality Grade breakdown above, StoneCo Ltd. has a better overall quality grade than Fidelity National Information Services, Inc.. For investors who are looking for companies with higher quality than others in the same industry, StoneCo Ltd. could be a good stock to add to their portfolios. However, it’s important for investors to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Fidelity National Information Services, Inc. and StoneCo Ltd.’s Momentum Grades

Company	Ticker	Momentum
Fidelity National Information Services, Inc.	FIS	F
StoneCo Ltd.	STNE	F

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

Typically, AAII looks at the weighted relative strength over the trailing four quarters. The weighted four-quarter relative strength rank is the relative price change for each of the past four quarters. The most recent quarterly price change is given a weight of 40% and each of the three previous quarters are given a weighting of 20%.

Fidelity National Information Services, Inc. has a Momentum Score of 18, which is Very Weak. StoneCo Ltd. has a Momentum Score of 13, which is Very Weak.

Fidelity National Information Services, Inc. and StoneCo Ltd.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
Fidelity National Information Services, Inc.	FIS	C
StoneCo Ltd.	STNE	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.

Fidelity National Information Services, Inc. has a Earnings Estimate Score of 50, which is Neutral. StoneCo Ltd. has a Earnings Estimate Score of 47, which is Neutral.

The Earnings Estimate Revisions Stock Winner: No Clear Winner

Other Fidelity National Information Services, Inc. and StoneCo Ltd. Grades

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

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.

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.

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 Fidelity National Information Services, Inc. and StoneCo Ltd. pass any of our 60+ stock screens that have outperformed the market since their creation.
