For new and old investors, taking full advantage of the stock market and investing with confidence are common goals. Zacks Premium provides lots of different ways to do both.

The popular research service can help you become a smarter, more self-assured investor, giving you access to daily updates of the Zacks Rank and Zacks Industry Rank, the Zacks #1 Rank List, Equity Research reports, and Premium stock screens.

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 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, on the other hand, are more concerned with a company's financial strength and health, and its future outlook. The Growth Style Score examines things like projected and historic earnings, sales, and cash flow to find stocks that will experience sustainable growth over time.

Momentum Score

Momentum investors, who live by the saying "the trend is your friend," are most interested in taking advantage of upward or downward trends in a stock's price or earnings outlook. Utilizing one-week price change and the monthly percentage change in earnings estimates, among other factors, the Momentum Style Score can help determine favorable times to buy 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.

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.

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.

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.

For instance, a stock with a #4 (Sell) or #5 (Strong Sell) rating, even one that boasts Scores of A and B, still has a downward-trending earnings forecast, and a much greater likelihood its share price will decline as well.

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