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.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.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 ScoreValue investors love finding good stocks at good prices, especially before the broader market catches on to a stock's true value. Utilizing ratios like P/E, PEG, Price/Sales, Price/Cash Flow, and many other multiples, the Value Style Score identifies the most attractive and most 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.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.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.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.Stock to Watch: Stanley Black & Decker (SWK)Headquartered in New Britain, CT, Stanley Black & Decker, Inc. manufactures and provides tools (power and hand tools) and related accessories, healthcare solutions, electronic security solutions, engineered fastening systems, and many more items and services.SWK is a #3 (Hold) on the Zacks Rank, with a VGM Score of B.Momentum investors should take note of this Industrial Products stock.
