It’s a portfolio made up of 50 stocks that are set to beat the market over the next 12 months; each company selected serves as a foundation for long-term investors looking to create an individual portfolio.Additionally, each selection is accompanied by a full Zacks Analyst Report, something that makes the Focus List even more valuable. The report explains in detail why each stock was picked and why we believe it’s good for the long-term.The portfolio’s past performance only solidifies why investors should consider it as a starting point. For 2020, the Focus List gained 13.85% on an annualized basis compared to the S&P 500’s return of 9.38%. Cumulatively, the portfolio has returned 2,519.23% while the S&P returned 854.95%. Returns are for the period of February 1, 1996 to March 31, 2021. Focus List MethodologyWhen stocks are picked for the Focus List, it reflects our enduring reliance on the power of earnings estimate revisions.Earnings estimates, or expectations of growth and profitability, come from brokerage analysts who track publicly traded companies; these analysts work together with company management to analyze every aspect that may affect future earnings, like interest rates, the economy, and sector and industry optimism.Investors also need to look at what a company will earn down the road. This is why earnings estimate revisions are so important.When a stock receives upward earnings estimate revisions, it will likely get even more positive changes in the future. For instance, if an analyst raised their earnings outlook last month, they’ll probably do so again this month, and other analysts will follow.Harnessing the power of earnings estimate revisions is where the Zacks Rank comes in. The Zacks Rank is a unique, proprietary stock-rating model that utilizes changes to a company’s quarterly earnings expectations to help investors build a winning portfolio.There are four main factors behind the Zacks Rank: Agreement, Magnitude, Upside, and Surprise. Each one of these features is then given a raw score that’s recalculated every night and compiled into the Rank. Using this data, stocks are classified into five groups, ranging from “Strong Buy” to “Strong Sell.”The Focus List is comprised of stocks hand-picked from a long list of #1 (Strong Buy) or #2 (Buy) ranked companies, meaning that each new addition boasts a bullish earnings consensus among analysts.Because stock prices react to revisions, buying stocks with rising earnings estimates can be very profitable. Focus List stocks offer investors a great opportunity to get into companies whose future earnings estimates will be raised, potentially leading to price momentum. Focus List Spotlight: Shopify (SHOP)Ottawa, Canada-based Shopify Inc. provides a multi-tenant, cloud-based, multi-channel commerce platform for small and medium-sized businesses (SMBs).
