According to Yury Shmidt, one of Russia's top lawyers and a member of Khodorkovsky's defense team, the investigation will be completed by May, and then the trial may start in June or July.
Khodorkovsky faces up to 10 years in prison if convicted.
Shmidt said he believed the affair was politically motivated and added that the oil magnate still denied any wrongdoing despite publishing an article earlier this month, which many analysts said was an attempt to clinch a compromise with the Kremlin.
"He doesn't plead guilty to any of 11 charges," said Shmidt.
Shares of Yukos almost reached their all-time high last week and closed slightly up on the RTS exchange Monday, roughly in line with the broader market.
