The three major indexes are on their way toward weekly losses, but handful of stocks have managed to stand out in an otherwise downcast week. CNBC Pro used FactSet data to scan the stock market to find the biggest winners of the week — and then looked to find out where Wall Street thinks these stocks are headed in coming months. Our screen of large-cap, mid-cap and small-cap stocks in the S & P 1500 resulted in a variety of winners, including a logistics company and a promising medical device play. One name that stuck out on the list was once-troubled regional bank PacWest Bancorp , which jumped almost 12% this week as of Friday morning. Wall Street believes shares have 55% upside, according to the consensus 12-month price target set by analysts. PacWest shares had a strong week after regional banking peer Western Alliance Bancorp posted quarterly adjusted earnings, according to FactSet. The results boosted sentiment surrounding regional bank shares. Investors were further buoyed by Western Alliance's announcement that its deposits have been recovering in April after falling 11% in the first quarter. PacWest is set to report its earnings next week. Half of the analysts covering the stock rate it a buy.
