Ward was undeterred in a "Squawk Box" interview, saying that investors should "buy it again or buy it."
"This is a company that's made more money for shareholders in the last few years than the entire rest of the technology industry combined," he said.
"At 4.7 times earnings before interest, taxes, depreciation, and amortization (EBITDA: CNBC Explains), a 50 percent discount to IBM — which has grown revenues by 1 percent for the past five years — Apple is extremely cheap."
Apple has been under pressure recently from hedge fund manager David Einhorn, who spoke on "Squawk Box" two weeks ago about his call for a distribution of perpetual preferred stock. Now he's taking his case directly to investors to explain why he's pushing the company to share its treasure trove of cash.

Gamco's Ward wouldn't pass judgment on Einhorn's actions but said Apple should be given the benefit of the doubt. "They didn't even have a dividend 12 months ago."
"I think we're being a little too hasty in pushing them," he added. "I think they'll do the right thing. I think they'll return cash to shareholders. No question about it."
