While the overall market may be down Friday, shares of Walmart (WMT - Get Report) are slightly higher on the day following an upgrade to outperform and $80 price target from the analysts at Credit Suisse. 

"This was a good call," TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, said on CNBC's "Mad Dash" segment. 

The retailer is doing a lot of good things, he said, particularly with its employees. Instead of allowing a high churn rate to plague its employment process, management is working on training and keeping its employees at the company, Cramer explained. 

He said this is exactly what Jim Sinegal said needed to happen in order for big retail chains to turn things around -- Jim Sinegal being the co-founder and former CEO of AAP holding Costco (COST) . Walmart and others spend too much money to hire and train new employees just to see them leave, Cramer reasoned. 

Walmart's Jet.com acquisition is a "wild card" but it could help the company fight against Amazon (AMZN - Get Report) , he added. 

"I like the call" because the stock has moved lower in recent weeks, but the estimates are still very beatable, Cramer concluded. 

At the time of publication, Cramer's Action Alerts PLUS had a position in COST.
