Hong Kong prosecutors say Bank of America traders shared details of a 2017 Esprit Holdings block sale with Segantii Capital Management without first taking the formal step known as wall-crossing.

The claim cuts to the center of how sensitive market information should move between banks and investors during large share sales. In court on Monday, prosecutors outlined their view that traders working on the Esprit transaction disclosed some information about the potential deal before placing Segantii behind the usual confidentiality barrier that governs such discussions.

The prosecution’s account frames the case around timing: when information moved, what kind of information it was, and whether standard market safeguards came too late.

The dispute reaches back to a block trade in shares of fashion retailer Esprit Holdings. Reports indicate the proceedings focus on what Bank of America employees told Segantii and when they told it, not simply on the existence of the sale itself. That sequence matters because wall-crossing marks a clear line in many market transactions, signaling that an investor may receive confidential details and accept restrictions on trading.

Key Facts

  • Hong Kong prosecutors addressed the issue in court on Monday.
  • The matter involves a 2017 block sale in Esprit Holdings shares.
  • Prosecutors say Bank of America traders did not wall-cross Segantii before disclosing some deal information.
  • The case centers on the timing and handling of potentially sensitive market information.

The prosecution’s argument also highlights a broader tension in modern markets: block trades depend on speed, but speed cannot erase the rules around information-sharing. Sources suggest the case will continue to test how clearly those rules were followed in practice and how tightly courts expect banks and hedge funds to observe them when lining up major stock transactions.

What happens next matters beyond one 2017 trade. The court’s handling of the allegations could shape how banks approach pre-deal conversations, how investors respond to early calls on block sales, and how aggressively regulators and prosecutors police the line between market soundings and improper disclosure.
