Jim Cramer Says Own Salesforce.com, Regeneron, First Solar

TheStreet's Action Alerts PLUS Portfolio Manager Jim Cramer says Macy's should benefit from the cold weather and energy stocks are still 'too dangerous' to put money into. On Facebook, Denise Brooks asks what she should do with Macy's and Walmart. Cramer said it's time to buy Macy's (M) because the stock is too cheap. But, he said it's a different story for Walmart (WMT) because it's very hard to figure out what the future will hold. One suggestion is that the discount retailer should offer Amazon's (AMZN) biggest selling products, at a 10 percent discount. On the energy front, Joseph Brogan asks about Talen Energy (TLN). Cramer said Talen is 'part of the energy complex' and just like Southwestern Energy (SWN) and Chesapeake Energy (CHK) 'you can't own these stocks right now, they are just too dangerous.'
