Jim Cramer answered viewers' Twitter questions from the floor of the New York Stock Exchange, and talked about the Federal Reserve, oil stocks, and Twitter (TWTR). Cramer was asked whether good housing numbers help a company like Stanley Black & Decker (SWK). Cramer said he liked the company's last quarterly report and that he is bullish on the housing story. He talked about Home Depot (HD) and Whirlpool (WHR) and said when he sees housing-related stocks come down, he will buy them. Another viewer said he purchased Twitter shares below their IPO price and asked Cramer's opinion on the buy. Cramer responded that the lower the stock goes, the more likely there will be a bidding war for the company. He said the stock has been a disaster, and he owns it in his charitable trust. 'I thought that Twitter was better managed and I got that wrong,' Cramer said. Cramer also discussed oil stocks, after a viewer asked when he expected to see merger and acquisition activity among exploration and production companies. Cramer said there are still too many companies in the space that are able to get private equity funding. He noted that Freeport McMoran (FCX) cut its capital expenditure budget Thursday to increase its cash flow. Cramer added that Schulmberger's (SLB) purchase of Cameron (CAM) was important. He called it a defensive deal in case Baker Hughes (BHI) merges with Haliburton (HAL). For more of Jim Cramer's thoughts on stocks and the financial markets tweet to @JimCramer using #CramerQ.
