BusinessWorld has published a quick glance at how Philippine Stock Exchange index (PSEi) member stocks fared on Monday, August 24, 2026. The performance snapshot can be viewed on BusinessWorld Online.

The PSEi is the main benchmark index of the Philippine Stock Exchange, the operator of the country's sole stock exchange. It tracks the share-price performance of 30 of the bourse's largest and most actively traded listed companies, drawn from the exchange's major sectors: financials, industrials, holding firms, property, services, and mining and oil. Formerly known as the PHISIX, the index was renamed the PSEi in 2006. It is computed on a free-float-adjusted market capitalization basis, meaning each member's weight reflects the shares actually available for public trading rather than total listed shares.

The index serves as the primary barometer of the Philippine equity market and as a reference point for funds and index-linked products that track Philippine shares. Because it is weighted by free-float market capitalization, price moves in its larger constituents exert greater influence on the overall reading — one reason member-by-member breakdowns such as BusinessWorld's table are useful alongside the headline index move. The index's composition is reviewed periodically by the Philippine Stock Exchange, with membership based on criteria that include market capitalization, liquidity, and free float.
