The Brink's Company, Tetra Tech and Inc. Stock Value Grades

Company	Ticker	Value
The Brink's Company	BCO	B
Tetra Tech, Inc.	TTEK	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.

The Brink's Company has a Value Score of 64, which is Value. Tetra Tech, Inc. has a Value Score of 55, which is Average.

The Value Stock Winner: The Brink's Company

The Brink's Company, Tetra Tech and Inc. Growth Grades

Company	Ticker	Growth
The Brink's Company	BCO	A
Tetra Tech, Inc.	TTEK	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.

The Brink's Company has a Growth Score of 100, which is Very Strong. Tetra Tech, Inc. has a Growth Score of 89, which is Very Strong.

The Growth Grade Winner: It’s a Tie!

Company	Ticker	Momentum
The Brink's Company	BCO	D
Tetra Tech, Inc.	TTEK	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%.

The Brink's Company has a Momentum Score of 38, which is Weak. Tetra Tech, Inc. has a Momentum Score of 21, which is Weak.

Other The Brink's Company, Tetra Tech and Inc. Grades

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

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).

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 The Brink's Company, Tetra Tech and Inc. pass any of our 60+ stock screens that have outperformed the market since their creation.
