Consolidation chatter in the cable industry has stocks in the sector on the move.
Charter Communications shares were up more than 4 percent on a report from Bloomberg News that there are "discussions" between Charter and privately held Cox Communications.
Charter has indicated in the past a desire to consolidate, CNBC's David Faber reports, possibly with Time Warner Cable. That company's stock dropped nearly 3 percent, presumably on losing its "takeover premium" if Charter is indeed moving on.
Meanwhile, Cablevision shares are up nearly 7 percent. The jump—to highs not seen since August 2011— seems to be on a suggestion on the earnings call that the company is more open to a sale than in the past, Faber reports.
Cablevision stock hit a single-stock circuit breaker at 10:32 a.m. on unusual volume—a change of 10 percent or more within a five-minute period—up 4.6 percent.
