UGI Corporation, Southwest Gas Holdings and Inc. Stock Value Grades

Company	Ticker	Value
UGI Corporation	UGI	A
Southwest Gas Holdings, Inc.	SWX	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.

UGI Corporation has a Value Score of 84, which is Deep Value. Southwest Gas Holdings, Inc. has a Value Score of 51, which is Average.

The Value Stock Winner: UGI Corporation

As you can clearly see from the Value Grade breakdown above, UGI Corporation is considered to have better value than Southwest Gas Holdings, Inc.. For investors who focus solely on a company’s valuation, UGI Corporation 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.

UGI Corporation, Southwest Gas Holdings and Inc. Growth Grades

Company	Ticker	Growth
UGI Corporation	UGI	C
Southwest Gas Holdings, Inc.	SWX	D

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.

UGI Corporation has a Growth Score of 56, which is Average. Southwest Gas Holdings, Inc. has a Growth Score of 25, which is Weak.

The Growth Stock Winner: No Clear Winner

Neither UGI Corporation, Southwest Gas Holdings or Inc. has a high enough Growth 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.

UGI Corporation, Southwest Gas Holdings and Inc.’s Quality Grades

Company	Ticker	Quality
UGI Corporation	UGI	B
Southwest Gas Holdings, Inc.	SWX	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.

UGI Corporation has a Quality Score of 75, which is Strong. Southwest Gas Holdings, Inc. has a Quality Score of 57, which is Average.

The Quality Grade Winner: UGI Corporation

As you can clearly see from the Quality Grade breakdown above, UGI Corporation has a better overall quality grade than Southwest Gas Holdings, Inc.. For investors who are looking for companies with higher quality than others in the same industry, UGI Corporation 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.

Other UGI Corporation, Southwest Gas Holdings and Inc. Grades

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

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.

Earnings estimate revisions scores take into account the magnitude of a company’s earnings surprise in its last two reported fiscal quarters. Often, surprises beget further surprises‐or at least continued sales growth (the exact opposite is generally true, too).

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 UGI Corporation, Southwest Gas Holdings and Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
