On Thursday, shares of TreeHouse Foods closed higher, up $1.49, or 5.59% to $28.19. Shares of Taiwan Semiconductor closed higher too, up $0.25, or 2.89% to $8.91. Cramer interviewed Sam Reed, CEO of private label food maker TreeHouse, to find out if people really are choosing lesser expensive grocery products to save money. Reed confirmed Cramer's thesis, saying in general, private label products are enjoying accelerated growth. Also, even though the company has been hit with a rise in input costs, Reed said they've been actively managing other costs and improving efficiencies. Reed said TreeHouse will see the benefits of falling commodity prices in the second half of 2009, has a strong balance sheet and is ready to expand. Cramer said even though TreeHouse management is delivering, it appears the stock is still stalled. "That smells like opportunity to me," he concluded. Regarding Taiwan Semiconductor, Cramer said the company is the perfect way to play the Chinese economic recovery and stimulus package. Tuesday, Taiwan Semiconductor, which makes chips for industry giants like Qualcomm ( QCOM) and Intel ( INTC), is seeing strong demand from China. On the heels of a big partnership deal with Intel, Cramer said Taiwan Semi may look expensive at 27 times earnings, but noted that P/E ratios are the wrong metric to use. He said the company's price-to-book value is the ratio to use, and using that metric, Taiwan Semi still has room to run.
