ByMA presented its 2025 sustainability report on October 23, 2026, putting its role in Argentina's capital market back at the center of its investor-relations material. For ByMA stock, the key structural figure is the company's 99.96 percent stake in Caja de Valores, according to BYMA.

What does 99.96 percent mean?

The holding gives BYMA a central position in the post-trade infrastructure described on its investor-relations page. Caja de Valores handles the custody and registration of financial instruments, while BYMA itself operates the market, clearing house and issuing chamber, according to BYMA.

That structure matters because the company is not only tied to trading activity. Its stated services also include settlement, asset transfers, payment processing and shareholder-register administration. The report therefore provides a business-context update rather than a single operating metric.

Capital market role stays broad

BYMA says its platform connects liquidity, knowledge and professional market services for companies, institutions and individual investors. The company was created as a continuation of the Buenos Aires Stock Exchange and began trading on May 23, 2017, according to its investor-relations material.

The same page identifies Millennium as the technology platform supporting BYMA's operations and describes the group as a provider of secure market access. Its board has 11 members and an equal number of alternates, another governance detail relevant to the ownership structure.

Market value and trading context

The latest available home-market quote was ARS 244.25 on BYMA on October 23, 2026, at 4:59 p.m. ART. The stock's 52-week range was ARS 215.00 to ARS 351.75, while market capitalization stood at ARS 1.9 trillion on the same date. The quote sat ARS 29.25 above the lower end of that range.

For investors, the sustainability report adds context to those market figures: BYMA combines exchange operations with clearing, custody and registration services. Its ownership of 99.96 percent of Caja de Valores makes that integrated structure a central part of the company profile.
