Over the past month, Apple shares had tested, but failed to break through the $600 level. Much to Cramer's delight, though, the technology stock on Monday reached levels not seen since October 2012.

"This is finally the breakout I've been looking for," Cramer said on "Squawk on the Street."

Separately, Cramer thinks InterMune's stock could continue to rise. Shares of the biotechnology firm will likely benefit from a "very positive piece" published in The New England Journal of Medicine on Sunday, which touted InterMune's drug for the treatment of idiopathic pulmonary fibrosis.

"This is a drug that I truly believe in because remember that's a fatal disease and these guys have the real deal," Cramer said.

Finally, Cramer recommended investors watch Zillow. The online real estate database's stock recently popped. It has a heavy short interest, though. Should the stock reach the $111 level, Cramer thinks the shorts will pile on.
