5. -- Shares of Altice NV (ATCEY)  surged the most in two months in early trading on Thursday after the French telecommunications and cable group controlled by billionaire Patrick Drahi raised its stake in SFR Group SA (NUMCF) amid continued speculation it may be preparing a takeover bid for Charter Communications Inc. (CHTR) - Get Report .

Altice raised its stake in SFR, the French wireless operator, to more than 95% and said it's planning a full buyout offer for the remaining shares. The deal by TheStreet's calculations would be worth about €760 million ($890 million). 

The move by Altice comes amid speculation that it will make a bid for Charter Communications, as it looks to advanced the company's position in the U.S. The Drahi-controlled group is lining up a potential $185 billion bid for Charter, the Financial Times reported, citing sources close to the deal, pitting itself against Softbank Group Corp. (SFTBY) .

Shares of Charter rose 2.9% on Wednesday, Aug. 9, to $400.90.
