Four weeks after Liberty Media Chairman John Malone called Discovery Communications stock cheap, he appears to have put his money where his mouth is.

On Friday morning, Malone doubled his position in Discovery Class A Stock with the purchase of 332,523 shares, for $6.6 million dollars, according to a securities filing.



This position strengthens Malone's already hefty stake in Discovery's Class A stock, which now exceeds 670,000. The media titan also owns 95 percent of Class B and 5.9 percent of Class C shares — together worth more than $412 million dollars as on Friday's close, according to Factset.



Shares have Discovery have taken a beating since the company announced its $15 billion acquisition of Scripps Networks in July. At its November low, shares had fallen nearly 35 percent, on investor fears surrounding the combination's advertising and ratings growth in the evolving media landscape.
