Taking full advantage of the stock market and investing with confidence are common goals for new and old investors, and Zacks Premium offers many 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?

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

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 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

What if you like to use all three types of investing? The VGM Score is a combination of all Style Scores, making it one of the most comprehensive indicators to use with the Zacks Rank. It rates each stock on their combined weighted styles, which helps narrow down the companies with the most attractive value, best growth forecast, and most promising momentum.

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.

#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.

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.

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.
