Summary
Hong Kong's District Court commenced a landmark insider trading trial on May 4, 2026, with Segantii Capital Management, its founder Simon Sadler, and former trader Daniel La Rocca entering not guilty pleas. The trial, scheduled to run 25 days through June 8, centers on allegations that the defendants engaged in insider dealing involving 190 million shares of fashion retailer Esprit Holdings ahead of a block trade executed in June 2017.
The Securities and Futures Commission initiated criminal proceedings against the defendants in 2024, alleging they sold Esprit shares after receiving non-public information about the impending block sale. According to court documents, Tony Psarianos, a former banker at Bank of America, provided advance notice of the transaction to Segantii's La Rocca "before the market opened on the previous day of the block trade." The block trade itself was arranged by Bank of America's Merrill Lynch unit at the instruction of client Lone Pine Capital. Psarianos is expected to provide testimony on May 11 and 12.
The prosecution's case represents a significant regulatory moment for Hong Kong authorities, who have intensified their crackdown on insider dealing amid a surge in share sale activity across Asia. The trial's high profile reflects both the defendants' prominence in Asian capital markets and the SFC's commitment to enforcing insider trading restrictions in the block trade space, historically a complex and less transparent segment of equity markets.
The case has already resulted in operational consequences: Segantii's $5 billion fund has shut down following the charges. Sadler, who earned the epithet "block trade king" for his prominence in structured equity transactions, is also owner of Blackpool Football Club. District court judges may impose sentences of up to seven years imprisonment, underscoring the severity with which Hong Kong regulators are treating the alleged violations.
