What Bukuk Securities does

Bookook Securities Co., Ltd. (부국증권; KRX ticker A005930) is a South Korean full-service securities firm founded in August 1954 and headquartered at 17 Gukjegeumyung-ro 6-gil, Yeongdeungpo-gu, Seoul. The firm operates a vertically integrated brokerage and investment banking platform serving retail investors as its primary segment, complemented by institutional brokerage and corporate finance (IPO underwriting, corporate bond issuance, M&A advisory). It maintains three satellite branches in Seongnam, Goyang, and Bucheon, and leverages long-standing channel partnerships with Shinhan Bank (since May 2000) and KB Kookmin Bank (since October 2003) for nationwide account opening and deposit/withdrawal services.

The core technology stack is built around proprietary trading platforms: BestWay Plus (desktop HTS) and Best-M Plus (mobile MTS), both positioned as industry-leading in execution speed and stability, plus the BK Doctor stock-analysis portal and a new NXT alternative-trading venue participation for Q3 2026. Authentication is delivered via the KOSCOM joint certificate system, and trading infrastructure runs on KOSCOM WTS. The firm also publishes the 부국 Daily research series (8,700+ issues by July 2026), corporate analysis reports, and weekly/monthly investment briefs.

Revenue is generated through a diversified mix of brokerage commissions (tiered by transaction size and instrument, with HTS/MTS users receiving discounted rates), proprietary securities trading gains at fair value through profit or loss, derivative trading gains, interest income from margin lending and deposits, and sales commissions on funds, MMF, bonds, and ETFs. Group affiliates include Yurie Asset Management (asset management) and Bookook Capital (capital services), enabling intra-group cross-sell of investment products. FY2025 consolidated operating revenue was KRW 913.3 billion with net income of KRW 32.4 billion, up 43% from KRW 22.6 billion in FY2024, against stockholder equity of KRW 760.4 billion.
