What are the Zacks Style Scores?

Developed alongside the Zacks Rank, the Zacks Style Scores are a group of complementary indicators that help investors pick stocks with the best chances of beating the market over the next 30 days.

Each stock is assigned a rating of A, B, C, D, or F based on their value, growth, and momentum characteristics. Just like in school, an A is better than a B, a B is better than a C, and so on -- that means 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

Growth investors are more concerned with a stock's future prospects, and the overall financial health and strength of a company. Thus, the Growth Style Score analyzes characteristics like projected and historic earnings, sales, and cash flow to find stocks that will see sustainable growth over time.

Momentum Score

Momentum traders and investors live by the saying "the trend is your friend." This investing style is all about taking advantage of upward or downward trends in a stock's price or earnings outlook. Employing factors like one-week price change and the monthly percentage change in earnings estimates, the Momentum Style Score can indicate favorable times to build a position in high-momentum stocks.

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 +25.41% 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.

You want to make sure you're buying stocks with the highest likelihood of success, and to do that, you'll need to pick stocks with a Zacks Rank #1 or #2 that also have Style Scores of A or B. If you like a stock that only as a #3 (Hold) rank, it should also have Scores of A or B to guarantee 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.

A stock with a #4 (Sell) or #5 (Strong Sell) rating, for instance, even one with Scores of A and B, will still have a declining earnings forecast, and a greater chance its share price will fall too.

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