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.Featuring daily updates of the Zacks Rank and Zacks Industry Rank, full access to the Zacks #1 Rank List, Equity Research reports, and Premium stock screens, the research service can help you become a smarter, more self-assured investor.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.Based on their value, growth, and momentum characteristics, each stock is assigned a rating of A, B, C, D, or F. The better the score, the better chance the stock will outperform; an A is better than a B, a B is better than a C, and so on.The Style Scores are broken down into four categories:Value ScoreFinding 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 ScoreWhile 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 ScoreMomentum 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 ScoreIf 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 RankThe 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.Investors can count on the Zacks Rank's success, with #1 (Strong Buy) stocks producing an unmatched +25.41% average annual return since 1988, more than double the S&P 500's performance. But the model rates a large number of stocks, and there are over 200 companies with a Strong Buy rank, plus another 600 with a #2 (Buy) rank, on any given day.But it can feel overwhelming to pick the right stocks for you and your investing goals with over 800 top-rated stocks to choose from.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.Since the Scores were created to work together with the Zacks Rank, the direction of a stock's earnings estimate revisions should be a key factor when choosing which stocks to buy.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.Stock to Watch: Hilton Worldwide Holdings Inc.
