Sharplink, Inc. and Marex Group Limited’s Quality Grades

Company	Ticker	Quality
Sharplink, Inc.	SBET	C
Marex Group Limited	MRX	F

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.

Sharplink, Inc. has a Quality Score of 41, which is Average. Marex Group Limited has a Quality Score of 20, which is Very Weak.

The Quality Stock Winner: No Clear Winner

Neither Sharplink, Inc. or Marex Group Limited 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 Sharplink, Inc. or Marex Group Limited is the better investment when it comes to quality.

Sharplink, Inc. and Marex Group Limited’s Momentum Grades

Company	Ticker	Momentum
Sharplink, Inc.	SBET	D
Marex Group Limited	MRX	A

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%.

Sharplink, Inc. has a Momentum Score of 29, which is Weak. Marex Group Limited has a Momentum Score of 89, which is Very Strong.

The Momentum Grade Winner: Marex Group Limited

As you can clearly see from the Momentum Grade breakdown above, Marex Group Limited is considered to have stronger momentum compared to Sharplink, Inc.. For those specifically looking for companies that have stronger momentum compared to other companies in the same industry, Marex Group Limited could be a good stock to invest in. However, it’s important for investors to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

Sharplink, Inc. and Marex Group Limited’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
Sharplink, Inc.	SBET	na
Marex Group Limited	MRX	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.

Sharplink, Inc. does not have a meaningful Earnings Estimate Score. Marex Group Limited has a Earnings Estimate Score of 83, which is Very Positive.

The Earnings Estimate Revisions Stock Winner: Undetermined

If you are strictly an investor who focuses on earnings estimate revisions, you may want to add Marex Group Limited to your watch list. 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 Sharplink, Inc. and Marex Group Limited Grades

In addition to Quality, Estimate Revisions and Momentum, 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 Sharplink, Inc. and Marex Group Limited pass any of our 60+ stock screens that have outperformed the market since their creation.
