Jim Cramer -- Dollar General Hurt by Food Prices

Shares of Dollar General (DG) are down more than 6% after the company reported disappointing earnings. 

Investors were looking for positive same-store sales and the company reported a 1% drop, TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, said Thursday on CNBC's "Mad Dash" segment. 

The negative comparisons go along witha miss on earnings per share and revenue expectations for the quarter, he added. 

Investors had bought into Dollar General, thinking it would report good earnings as Dollar Tree (DLTR) did a few weeks ago. However, Dollar General carries more food products than Dollar Tree, and food pricing negatively impacted the company, Cramer explained. 

Investors have seen a similar impact to Kroger (KR) , he added. On Wednesday, Cramer said he preferred other retailers -- including TJX (TJX) and Nordstrom (JWN)  -- over the dollar stores. 

Elsewhere in retail, Cramer turned to PVH (PVH) , which beat on earnings per share and revenue results. The stock is up about 3% as a result. 

Sales at its department stores have been "very strong" since the election, Cramer said, adding that international sales, particularly in China, have also been very impressive. 

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