It doesn't matter your age or experience: taking full advantage of the stock market and investing with confidence are common goals for all investors. Luckily, Zacks Premium offers several different ways to do both.The research service features 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, all of which will help you become a smarter, more confident investor.Zacks Premium includes access to the Zacks Style Scores as well.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 ScoreFor 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 ScoreGrowth 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 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 RankA proprietary stock-rating model, the Zacks Rank utilizes the power of earnings estimate revisions, or changes to a company's earnings outlook, to help investors create 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 maximize your returns, you want to buy stocks with the highest probability of success. This means picking stocks with a Zacks Rank #1 or #2 that also have Style Scores of A or B. If you find yourself looking at stocks with a #3 (Hold) rank, make sure they have Scores of A or B as well to ensure 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.Stock to Watch: Macy's (M)Macy's is in the process of a complete makeover and has outlined plans under its three-year Polaris Strategy to adapt better to the new retail ecosystem.
