Time for 'Mad Mail!'

It's Thursday and that means it's time for some "Mad Mail!"

First, a homegamer asked Cramer whether he recommends avoiding ON Semiconductor's stock on the basis it was recently downgraded by UBS, or if he would hold onto shares until the tech company reports in a few weeks. After recently speaking with several technology companies' CEOs, Cramer learned that business is slow. He thinks the UBS analyst's call was forward-thinking and would avoid shares of ONNN right now.

Meanwhile, Jim in Washington wondering whether Cramer thinks GNC's stock could continue to go higher. Cramer thinks it can because it's part of the bull market in healthy foods. He thinks it could go to the mid-$20s.

Susan in California wanted to know whether BP Prudhoe Bay Royalty Trust is a good addition to her retirement portfolio. After all, she noted it pays a massive dividend yield. Cramer likes its 9.1 percent dividend yield and thinks she could make a lot of money should the price of oil stabilizes.

Rick in Texas asked about Core Labs . Cramer blessed this stock because the company is "intregal to the oil renaissance in this country."
