TriQuint Semiconductor took a big hit on Thursday after missing the Street’s revenue estimates and offering reduced guidance. The company also warned that a Korean handset maker, thought to be Samsung, would slow production. As a result, the stock dropped to $5.84 from Wednesday’s close of $8.10 on the news, a 28% decline.

• Cramer's 12 Stocks to Play the Recovery

But Cramer doesn’t think the move was justified. TriQuint largely was dragged down by its exposure to regular mobile phones, rather than smartphones, and Korean company’s cutbacks seem to be an isolated incident. While the Mad Money host did admit that he should have told investors to take profits much earlier in TQNT – he first recommended it on June 12 – he said the stock is attractive at this level, calling the sell-off “an opportunity to buy.”

On a related note, Skyworks Solutions and RF Micro Devices , both members of Mad Money’s Mobile Internet Index, also fell today, as a result of TriQuint’s quarter. It’s true that Skyworks and RF Micro do a lot of business with Samsung, Cramer said, but now the potential bad news is priced into their stocks. The mobile Internet is a “massive, multiyear theme,” so investors should use the 4% and 5% dips, respectively, to buy SWKS and RFMD at a discount.

“The worst that happens is [they] go down further,” Cramer said, “and you get to buy some more and lower and better prices.”
