Jim Cramer answers viewers' Twitter (TWTR) questions from the floor of the New York Stock Exchange. One viewer asked about Magellan Midstream Partners (MMP), which Jim said is a good company, but as interest rates go higher that stock will go lower. Within the energy space, Jim also likes Energy Transfer (ETP) and Kinder Morgan (KMI). Jim was also asked whether Kraft (KRFT) is a buy if its deal with Heinz goes through. Jim said 'absolutely yes, Kraft is going to be a winner, they'll be able to make acquisitions, it's a terrific situation.' Heinz and Kraft agreed to merge in March, and Kraft shareholders are set to vote on the deal next week. Jim was asked if the new Trans-Pacific Partnership will help Nike (NKE) move to new highs. He said you should buy Nike stock because their direct-to-consumer business is great and they are hitting on all cylinders. Another viewer asked about whether to sell a position in Keurig Green Mountain (GMCR). Jim said 'they had a horrible quarter, maybe the worst of any company during the year.' He added that at a certain point Coca-Cola (KO) might buy them. He suggests owning Monster Beverage (MNST), and he has a $162 price target on the stock.
