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.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?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.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 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 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.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 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.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.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: Builders FirstSource (BLDR)Builders FirstSource is the largest supplier of building materials, manufactured components and construction services to professional homebuilders, sub-contractors, remodelers and consumers.
