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 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.Zacks Premium also includes the Zacks Style Scores.What are the Zacks Style Scores?The Zacks Style Scores is a unique set of guidelines that rates stocks based on three popular investing types, and were developed as complementary indicators for the Zacks Rank. This combination helps investors choose securities with the highest 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 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 ScoreGrowth investors are more concerned with a stock's future prospects, and the overall financial health and strength of a company. Thus, the Growth Style Score analyzes characteristics like projected and historic earnings, sales, and cash flow to find stocks that will see sustainable growth over time.Momentum ScoreMomentum 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 ScoreIf you like to use all three kinds of investing, then the VGM Score is for you. It's a combination of all Style Scores, and is an important indicator to use with the Zacks Rank. The VGM Score rates each stock on their shared weighted styles, narrowing down the companies with the most attractive value, best growth forecast, and most promising momentum.How Style Scores Work with the Zacks RankThe 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.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.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.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: Hilton Worldwide Holdings Inc.
