Take a look at some of Tuesday's midday movers:
Freeport-McMoran Copper & Gold rallied after CEO Richard Adkerson said shareholders would not get a vote on its planned acquisitions of two oil and natural gas companies.
Google fell below its 50-day moving average ahead of the search giant's fourth-quarter results expected after the closing bell.
Coach also fell ahead of its quarterly earnings report Wednesday morning. Meanwhile, CLSA cut the luxury retailer to "outperform" from "buy" with a price target of $71, down from $79 per share.
Western Digital rose ahead of its earnings report Wednesday. In addition, the data storage provider is expanding its product portfolio to address the needs of small and medium-sized businesses.
Regions Financial gained after reporting a fourth-quarter profit. The regional lender was helped this quarter by favorable comparisons to its year ago report and a large write-down related to the sale of its brokerage unit.
