Company	Ticker	Growth
RingCentral, Inc.	RNG	A
Pegasystems Inc.	PEGA	A

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.

RingCentral, Inc. has a Growth Score of 89, which is Very Strong. Pegasystems Inc. has a Growth Score of 89, which is Very Strong.

Company	Ticker	Momentum
RingCentral, Inc.	RNG	A

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

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%.

Company	Ticker	Earnings Estimate
RingCentral, Inc.	RNG	C
Pegasystems Inc.	PEGA	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.

RingCentral, Inc. has a Earnings Estimate Score of 52, which is Neutral. Pegasystems Inc. has a Earnings Estimate Score of 21, which is Negative.

Other RingCentral, Inc. and Pegasystems Inc. Grades

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

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 Quality Grade comes from the ranking of key metrics. Specifically, the quality grade is the percentile rank of the composite 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 F-Score.

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 RingCentral, Inc. and Pegasystems Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
