Technology sector stocks are so cheap it's "ridiculous," Cramer said during Monday's Mad Money. Overconcern for their exposure to Europe “has created the same buying opportunity for tech that we saw in 2003.”

Following the dot-com bubble, Cramer said, everyone gave up on tech plays. But the sector continued to grow regardless, as cell phones improved, Google brought excitement to the Web and companies and individuals alike required more and more storage for their data. The stocks eventually pushed higher, and those who bet against the common wisdom made a lot of money.
