Jim Cramer says investors should sit-tight if they own natural gas and master limited partnership (MLPs) shares until they move higher. @J_Edgar28 wonders at what point you would get back into Chipotle (CMG) given their current issues. Cramer said, ‘that’s become an emotional stock. We don’t want to draw a conclusion that Boston College has E. coli. We don’t know. Understand that Chipotle, six months from now, could be higher than it is.’ @rajquest asks about Freeport-McMoRan (FCX) and what the future holds for gold. ‘I don’t think that company can stay in it its current structure. The oils are so oversold that if you wanted to get in them, that’s wrong. But, if you want to wait for a bounce, that’s right. And, gold is having a very odd move here. I don’t want to own gold other than an insurance policy. That’s why I’ve always said 10-percent of your portfolio can be gold.’ @TigernBham asks about R.R. Donnelley (RRD). Cramer said, ‘It has a good yield, splitting into three companies, and the dividend is covered, where I think it’s just a great investment to hold over the next 18 months.’ Send your questions to Jim Cramer on Facebook and Twitter - @JimCramer, using #CramerQ.
