TheStreet's Action Alerts PLUS Portfolio Manager Jim Cramer said Walmart (WMT) - Get Report needs to guide down. The company releases results for its latest quarter on Thursday before the markets open. Cramer also says the retailer's recent acquisition of Jet.com will be good for Walmart. "I am inclined to like Target (TGT) - Get Report more than Walmart, even after the run of Target," he said. Target topped Wall Street's earnings estimates on Wednesday and reported a 26% increase in digital sales. Shares of Walmart are up roughly 17% so far this year.
