Jim Cramer answers viewers' Twitter (TWTR) questions from the floor of the New York Stock Exchange. He weighs in on IBM (IBM), which saw its international business hurt by the strength of the U.S. dollar. Cramer advises those who believe the dollar has peaked to buy IBM. With one viewer noting that analysts seem split on Corning (GLW), Cramer says it's too much of a battleground and he would stay away. He also sheds light on Shake Shack (SHAK), which he believes won't peak until the company does some sort of secondary. Plus, Cramer offers advice on whether to stay with Walmart (WMT) or get out, if Merck's (MRK) at a good level and what to expect from Chesapeake Energy (CHK) after its run last week.
