Amid the market volatility, there are some names that stand out as winners, according to Wall Street analysts. The stock market , which had enjoyed recent gains this summer, took a turn last week. The S & P 500 snapped its four-week winning streak on Friday, as experts debated whether or not the market's recent rally was a bear market bounce . The index is up about 15% since the June 17 intraday low. When investing in this environment, it pays to focus on the fundamentals, which analysts pour over when deciding whether to recommend a stock. What follows are companies that are well liked by Wall Street analysts. To find these names, CNBC Pro looked for stocks that have buy ratings from at least 60% of the analysts covering them and upside to the median price target of at least 10%. All names are in the S & P 500. The data on buy ratings and median price targets mentioned below are from FactSet. Signature Bank tops the list with 100% of the analysts covering the stock giving it a buy rating. It has 27% upside to the median analyst price target. In a note earlier this month, Bank of America analyst Ebrahim H. Poonawala wrote that Signature was one of the banks that "offer an interesting risk/reward given their secular growth potential." Howmet Aerospace and Steris follow Signature with 85.7% of the analysts covering the stocks rating them a buy. Howmet, already up 18% year to date, has 11.9% upside, based on the median analyst price target. Steris, a provider of medical products and services, reported quarterly earnings slightly below expectations earlier this month. However, JPMorgan analysts said in a note after the release that "aside from current macro headwinds, STE's business remains strong." Steris has 12.1% upside to the median price target. When it comes to those with the largest potential gains ahead, Schlumberger stands out in the crowd with 34.7% upside, according to the median analyst price target. The oilfield services company, which is benefiting from the rise in oil prices, is already up about 24% year to date. Of those analysts who cover the stock, 82.1% rate it a buy. Alaska Air and Generac Holdings also stand to potentially make some large gains. Both have 31.7% upside, according to the median analyst price targets. Of the analysts who cover Alaska Air, 84.6% rate it a buy, while 81.8% of the analysts covering Generac Holdings give it a buy rating. Alaska Air is down almost 13% for the year, and Generac Holdings has more than 27%.
