Amid market volatility, there are a few 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 pundits debated whether or not the market’s recent rally was a bear market bounce. The index has risen 15% since the intraday low of June 17. When investing in this environment, it pays to focus on fundamentals, which analysts weigh when deciding whether to recommend a stock. What follows are companies that are highly valued by Wall Street analysts. To find these names, CNBC Pro looked for stocks that had buy ratings from at least 60% of the analysts who cover them and to the upside of the average price target of at least 10%. All names are in the S&P 500. Data on buy ratings and average price targets mentioned below comes from FactSet. Signature Bank leads the list with 100% of analysts covering the stock giving it a buy rating. It has 27% upside from the average 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 “offers an interesting risk/reward given its secular growth potential.” Howmet Aerospace and Steris follow Signature with 85.7% of analysts covering the stock rating them a buy. Howmet, already up 18% year-to-date, has 11.9% upside, according to the analyst’s average price target. Steris, a provider of medical products and services, reported quarterly earnings that were slightly below expectations earlier this month. However, JPMorgan analysts said in a note after the release that “current headwinds aside, STE’s business remains strong.” Steris has 12.1% upside from its average price target. When it comes to those with the biggest potential gains going forward, Schlumberger stands out from the crowd with 34.7% upside, according to analysts’ average price target. The oilfield services company, which is benefiting from rising 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 make big gains. Both are up 31.7%, based on analysts’ average price targets. Of analysts covering Alaska Air, 84.6% rate it a buy, while 81.8% of analysts covering Generac Holdings give it a buy rating. Alaska Air is down nearly 13% for the year, and Generac Holdings is up more than 27%.
