Concern Sitronics, a Russian technology company owned by conglomerate Sistema, has much to live up to when it launches its initial public offering in London this year.

Rambler Media, the first Russian technology company to list on London's Alternative Investment Market, has undergone a 170% rise in its share price, valuing it at $410m (€329m), since it floated in June. The internet search company raised $45 at its listing, when it was worth £154m (€221m).
