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 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

Finding good stocks at good prices, and discovering which companies are trading under their true value, are what value investors like to focus on. So, the Value Style Score takes into account ratios like P/E, PEG, Price/Sales, Price/Cash Flow, and a host of other multiples to highlight 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 is a proprietary stock-rating model that harnesses the power of earnings estimate revisions, or changes to a company's earnings expectations, to help investors build a successful portfolio.

#1 (Strong Buy) stocks have produced an unmatched +25.41% average annual return since 1988, which is more than double the S&P 500's performance over the same time frame. However, the Zacks Rank examines a ton of stocks, and there can be more than 200 companies with a Strong Buy rank, and another 600 with a #2 (Buy) rank, on any given day.

With more than 800 top-rated stocks to choose from, it can certainly feel overwhelming to pick the ones that are right for you and your investing journey.

That's where the Style Scores come in.

To have the best chance of big returns, you'll want to always consider stocks with a Zacks Rank #1 or #2 that also have Style Scores of A or B, which will give you the highest probability of success. If you're looking at stocks with a #3 (Hold) rank, it's important they have Scores of A or B as well to ensure as much upside potential as possible.

The direction of a stock's earnings estimate revisions should always be a key factor when choosing which stocks to buy, since the Scores were created to work together with the Zacks Rank.

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.
