Cramer told viewers not to be fooled by the following stocks, as they never offer any treats. "Invest anywhere else," he said.First on Cramer's trick-or-treat list were the airlines. Cramer said just because the plane is full, it doesn't mean the company is making any money. He recalled two horrid investments gone wrong, People's Express and a former incarnation of American Airlines, both in the 1980s. Cramer said the airlines always have fuel problems, high labor costs and are in a business that's highly cyclical. "Don't even think about the airline stocks," he concluded. Next on the list were the gold miners. Cramer said he's recommended some gold stocks on "Mad Money" in the past, only to be disappointed. "No more," he said, as even when these companies deliver their best, it never seems to be good enough. Cramer said investors who want to play gold need to own the bullion or SPDR Gold Shares (GLD), not the mining stocks. Also on the list, supermarkets. Cramer said this business is cut-throat and has lots of waste. He said stocks like Kroger (KR), Supervalu (SVU) and Safeway (SWY) are just tough to own. Cramer recommended only Whole Foods (WFM), a healthy play the operates above the competition since they have pricing power. Finally, Cramer offered up two tech stocks, Advanced Micro Devices (AMD) and Micron Technologies (MU), two "perennial single-digit midgets." Cramer said these two companies are always getting undercut by competitors and investors need to stay away.
