MGE Energy, Inc. and OGE Energy Corp. Growth Grades

Company	Ticker	Growth
MGE Energy, Inc.	MGEE	B
OGE Energy Corp.	OGE	C

The foundation of growth investing is seeking out stocks of companies exhibiting strong, consistent and prolonged growth that is expected to continue into the future.

In order to compute the growth score and assign it a letter grade, the percentile ranks for each of three components‐consistency of annual sales growth, five-year sales growth rankings adjusted for extreme levels, and consistency of positive annual cash from operations‐must be determined. These three rank figures are added together, and the sum is ranked against the entire stock universe to arrive at a company’s Growth Score to create an equal distribution of grades.

The companies in the bottom 20% of the stock universe receive Growth Grades of F, considered to be very weak, while those in the top 20% receive A grades, which are considered very strong.

MGE Energy, Inc. has a Growth Score of 77, which is Strong. OGE Energy Corp. has a Growth Score of 47, which is Average.

The Growth Grade Winner: MGE Energy, Inc.

As you can clearly see from the Growth Grade breakdown above, MGE Energy, Inc. has a more attractive growth grade than OGE Energy Corp.. For investors who focus solely on how a company is growing relative to other companies in the same industry, MGE Energy, 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.

MGE Energy, Inc. and OGE Energy Corp.’s Quality Grades

Company	Ticker	Quality
MGE Energy, Inc.	MGEE	D
OGE Energy Corp.	OGE	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.

MGE Energy, Inc. has a Quality Score of 37, which is Weak. OGE Energy Corp. has a Quality Score of 47, which is Average.

The Quality Stock Winner: No Clear Winner

Neither MGE Energy, Inc. or OGE Energy Corp. 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 MGE Energy, Inc. or OGE Energy Corp. is the better investment when it comes to quality.

MGE Energy, Inc. and OGE Energy Corp.’s Estimate Revisions Grades

Company	Ticker	Earnings Estimate
MGE Energy, Inc.	MGEE	B
OGE Energy Corp.	OGE	D

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.

MGE Energy, Inc. has a Earnings Estimate Score of 61, which is Positive. OGE Energy Corp. has a Earnings Estimate Score of 36, which is Negative.

The Earnings Estimate Revisions Grade Winner: MGE Energy, Inc.

As you can clearly see from the Earnings Estimate Revisions Grade breakdown above, MGE Energy, Inc. has a better Earnings Estimate Revisions Grade than OGE Energy Corp.. For those who are specifically looking for companies with better short-term prospects when compared to other companies in the same industry, MGE Energy, 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 MGE Energy, Inc. and OGE Energy Corp. Grades

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

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 MGE Energy, Inc. and OGE Energy Corp. pass any of our 60+ stock screens that have outperformed the market since their creation.
