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.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.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 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 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 ScoreWhat 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 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.#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.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.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: Truist Financial Corporation (TFC)Truist Financial, formed following the ‘merger of equals’ deal between BB&T Corp and SunTrust Banks, is the sixth largest bank in the United States.
