George Economou's ownership of DryShips continues to get stronger after yet another round of share buybacks.
The company's chief executive now controls 78.3% of the New York-traded company's shares, up from 74.1% in August, according to filings made with the Securities and Exchange Commission Thursday.
In February, shareholders approved a year-long $50m buyback plan. That was completed in October, at which point an identical plan was approved.
The announcement was made after Nasdaq closed, when shares were down 2.51% to $5.82.
