Blockbuster ( BBI), Rite Aid ( RAD), Denny's ( DENN) and Level 3 ( LVLT) are single-digit stocks that are going much higher, Jim Cramer said Wednesday on CNBC's Stop Trading segment.

Cramer said these underappreciated names are "levitating" as investors catch on to the strength of their stories. Cramer said Rite Aid will rise because it's buying the Eckerd stores from Jean Coutu for what will turn out to be a song. He said Blockbuster is making inroads on Netflix ( NFLX), Denny's is hated despite signs of progress and Level 3 is making wise acquisitions that let analysts raise numbers.

As for this year's Lucky 13 stocks, Cramer likes Cisco ( CSCO) and food server Sysco ( SYY) but would avoid auto insurer Mercury General ( MCY).

At the time of publication, Cramer had no positions in stocks mentioned.
