Here's Why CoStar Group (CSGP) is a Strong Momentum Stock

It also includes access to the Zacks Style Scores.

What are the Zacks Style Scores?

The Zacks Style Scores, developed alongside the Zacks Rank, are complementary indicators that rate stocks based on three widely-followed investing methodologies; they also help investors pick stocks with the best chances of beating the market over the next 30 days.

Each stock is given an alphabetic rating of A, B, C, D or F based on their value, growth, and momentum qualities. With this system, an A is better than a B, a B is better than a C, and so on, meaning the better the score, the better chance the stock will outperform.

The Style Scores are broken down into four categories:

Value Score

For value investors, it's all about finding good stocks at good prices, and discovering which companies are trading under their true value before the broader market catches on. The Value Style Score utilizes ratios like P/E, PEG, Price/Sales, Price/Cash Flow, and a host of other multiples to help pick out the most attractive and discounted stocks.

Growth Score

While good value is important, growth investors are more focused on a company's financial strength and health, and its future outlook. The Growth Style Score takes projected and historic earnings, sales, and cash flow into account to uncover stocks that will see long-term, sustainable growth.

Momentum Score

Momentum trading is all about taking advantage of upward or downward trends in a stock's price or earnings outlook, and these investors live by the saying "the trend is your friend." The Momentum Style Score can pinpoint good times to build a position in a stock, using factors like one-week price change and the monthly percentage change in earnings estimates.

VGM Score

If you want a combination of all three Style Scores, then the VGM Score will be your friend. It rates each stock on their combined weighted styles, helping you find the companies with the most attractive value, best growth forecast, and most promising momentum. It's also one of the best indicators to use with the Zacks Rank.

How Style Scores Work with the Zacks Rank

The Zacks Rank, which is a proprietary stock-rating model, employs earnings estimate revisions, or changes to a company's earnings expectations, to make building a winning portfolio easier.

It's highly successful, with #1 (Strong Buy) stocks producing an unmatched +23.94% average annual return since 1988. That's more than double the S&P 500. But because of the large number of stocks we rate, there are over 200 companies with a Strong Buy rank, plus another 600 with a #2 (Buy) rank, on any given day.

This totals more than 800 top-rated stocks, and it can be overwhelming to try and pick the best stocks for you and your portfolio.

That's where the Style Scores come in.

To maximize your returns, you want to buy stocks with the highest probability of success. This means picking stocks with a Zacks Rank #1 or #2 that also have Style Scores of A or B. If you find yourself looking at stocks with a #3 (Hold) rank, make sure they have Scores of A or B as well to ensure as much upside potential as possible.

As mentioned above, the Scores are designed to work with the Zacks Rank, so any change to a company's earnings outlook should be a deciding factor when picking which stocks to buy.

Here's an example: a stock with a #4 (Sell) or #5 (Strong Sell) rating, even one with Style Scores of A and B, still has a downward-trending earnings outlook, and a bigger chance its share price will decrease too.

Thus, the more stocks you own with a #1 or #2 Rank and Scores of A or B, the better.
