Jim Cramer Cautious on Cliffs Natural Resources, Vale Even With Improving China

Jim Cramer says even with China improving, investors should avoid stock of Cliffs Natural Resources (CLF) and Vale (Vale). Cramer says Monsanto (MON) will pursue its proposed acquisition of Syngenta (SYT) even though there might be big antitrust issues. Cramer likes NXP Semiconductors (NXPI), as well as Qorvo (QRVO), Avago (AVGO), Skyworks (SKWS), but prefers Cypress (CY). Cramer says Town Sports (CLUB) is in a tough business and he prefers Under Armour (UA) and Nike (NKE). Cramer says Apple (AAPL) is a great long term own and you shouldn't trade it, even as the stock continues to churn. He answered Twitter questions on the floor of the NYSE.
