His earlier activities on the financial market in the 1990s included the acquisition of CS Fund, the asset manager of three smaller investment funds, which Tykač divested himself of just a few weeks before it was ‘tunneled’ or defrauded in March 1997. The most valuable acquisition of his investment company, Motoinvest, established in 1991, however, was Agrobanka. It was this company that financed most of Tykač’s activities, which before long led it to the brink of ruin as the bank was unable to meet its liabilities, leading to the intervention the Czech National Bank to rescue its clients by pumping CZK 20 billion into it. Tykač also acquired shares through Motoinvest in other banks whose capital was subsequently passed on to companies and funds linked to Tykač whereupon those banks also went bankrupt as a result of these transactions, e.g. Kreditní banka Plzeň, and Ekoagrobanka. As a result, he is often called "the pest of the capital market" in the Czech Republic, an appellation which he failed to have the Czech courts prohibit the magazine Respekt from using in connection with his person.
