Segantii Capital Management founder Simon Sadler told a Hong Kong court that personal and professional pressures had been mounting by 2017, the year his firm faces insider trading allegations regarding fashion retailer Esprit Holdings Ltd. The testimony came during the second day of his high-profile trial, where defense lawyers presented him as their first witness after a month of prosecution testimony.

The case centers on nine-year-old trades that prosecutors allege were based on non-public information. Sadler's account provides a window into the alleged timeframe of misconduct, coming after prosecution called two former Bank of America Corp traders to testify. The Hong Kong court proceedings have drawn significant attention to the hedge fund's trading practices during this period.

The testimony marks a critical phase in the insider trading case, with Sadler attempting to contextualize his firm's actions through the lens of mounting stress. The outcome could have substantial implications for how regulators view trading decisions during periods of personal and professional strain at financial institutions.
