Stephens analyst Matthew Marietta raised his price target for U.S. Silica to $24 from $19 on valuation. The analyst says the company's shares are up more than 100% off 2016 lows in mid-January, which has corresponded with a 35% increase in gravel, sand and stone rail carloads. He notes, however, that carloads have remained stable since February and says he believes investors have been rewarded for a recovery that has yet to occur. U.S. Silica remains well positioned from balance sheet and market share perspective, but when market positioning by investors creates opportunity, the analyst recommends investors to take advantage of it. Stephens has an Equal Weight on the shares.
