MOSCOW (Reuters) - Shares in Russian transport companies that are part-owned by Summa Group fell on Monday after its billionaire owner Ziyavudin Magomedov was detained on embezzlement charges.
Fesco (MM:FESH) was hardest hit, plunging 19.18 percent after Russian authorities arrested Magomedov and his brother on Saturday on charges of embezzling more than $35 million. It was one of the highest-profile prosecutions of a Russian tycoon in years.
Summa Group and U.S. private equity fund TPG own 49.9 percent of Fesco shares.
Summa also owns smaller stakes in Novorossiysk Commercial Sea Port Group (NCSP) (MM:NMTP), which was down around 1 percent, and Russia's largest freight container operator Transcontainer (MM:TRCN) which dropped 0.61 percent.
They bucked a rise in Russian stock indexes.
Summa Group owns 25 percent of NCSP and is currently involved in a dispute with state-owned oil pipeline operator Transneft over control of Russia's largest port operator.
Russia's anti-monopoly regulator has given Transneft the green light to acquire control of NCSP but a final agreement has not been reached yet.
If Transneft does increase its stake in NCSP, "it could be a trigger for the stock and imply the prospect of higher dividends," analysts at Alfa bank said in a note.
Transcontainer, meanwhile, is 25 percent owned by Fesco and analysts said Magomedov's detention could give Russian businessman Roman Abramovich, a co-owner of Transcontainer, an opportunity to increase his stake in the company.
Russia's dollar-denominated RTS index (IRTS) was up 0.69 percent by 1005 GMT at 1,256 points. The rouble-based MOEX Russian index (IMOEX) was 0.90 percent higher at 2,291 points.
The Russian rouble weakened on Monday as many markets around the world were closed for Easter holidays and as investors fretted about geopolitical tensions between Russia and the West.
