CACI International Inc, EPAM Systems and Inc. Stock Value Grades

Company	Ticker	Value
CACI International Inc	CACI	C
EPAM Systems, Inc.	EPAM	A

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.

CACI International Inc has a Value Score of 52, which is Average. EPAM Systems, Inc. has a Value Score of 84, which is Deep Value.

The Value Stock Winner: EPAM Systems, Inc.

As you can clearly see from the Value Grade breakdown above, EPAM Systems, Inc. is considered to have better value than CACI International Inc.

However, it’s important for investors to analyze multiple factors based on a wide range of metrics before deciding whether to buy.

CACI International Inc, EPAM Systems and Inc.’s Quality Grades

Company	Ticker	Quality
CACI International Inc	CACI	B
EPAM Systems, Inc.	EPAM	A

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.

CACI International Inc has a Quality Score of 66, which is Strong. EPAM Systems, Inc. has a Quality Score of 90, which is Very Strong.

The Quality Grade Winner: EPAM Systems, Inc.

As you can clearly see from the Quality Grade breakdown above, EPAM Systems, Inc. has a better overall quality grade than CACI International Inc. For investors who are looking for companies with higher quality than others in the same industry, EPAM Systems, Inc. could be a good stock to add to their portfolios.

CACI International Inc, EPAM Systems and Inc.’s Momentum Grades

Company	Ticker	Momentum
CACI International Inc	CACI	C
EPAM Systems, Inc.	EPAM	D

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%.

CACI International Inc has a Momentum Score of 45, which is Average. EPAM Systems, Inc. has a Momentum Score of 26, which is Weak.

The Momentum Stock Winner: No Clear Winner

Neither CACI International Inc, EPAM Systems or Inc. has a strong enough Momentum Grade to be considered a “winner.” Investors 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 CACI International Inc, EPAM Systems or Inc. is the better investment when it comes to momentum.

Other CACI International Inc, EPAM Systems and Inc. Grades

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

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).

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.

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 CACI International Inc, EPAM Systems and Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
