With its decision No. 57/1708 dated 17.09.2026, the Capital Markets Board (the “CMB”) set out the liquidation procedures for the 131 investment funds established by Tera, A1 Capital, Atlas, Bulls, Hedef, Pardus and Pusula Portföy Yönetimi, whose liquidation had been ordered under its previous decision, and updated the relevant list of funds in the same decision.

The sell-off was primarily triggered by a default at Pusula Portföy Yönetimi A.Ş., a portfolio management company, which failed to meet investor redemption requests from certain funds it manages in a timely manner. A similar liquidity problem emerged at Tera Portföy Yönetimi A.Ş., and this situation put pronounced pressure on the shares of both companies as well as on broader market indices.

It became apparent that the problem was not confined to those two firms but also extended to Hedef, Atlas, A1 Capital, Pardus and Bulls Portföy.
