BusinessWorld has published its regular daily recap of how member stocks of the Philippine Stock Exchange index (PSEi) performed on Thursday, October 1, 2026. Presented under the outlet's recurring "How PSEi member stocks performed" feature, the item offers readers a quick glance at the day's trading results for the benchmark gauge's constituents.

The PSEi is the main benchmark stock index of the Philippine Stock Exchange (PSE), the operator of the Philippines' national stock exchange. The index comprises 30 selected listed companies and is calculated on a free-float-adjusted market capitalization basis, a methodology that weights constituents according to the shares actually available for public trading rather than their total outstanding shares. It is widely used as a barometer of the overall direction of the Philippine equities market. Member-level rundowns like this one offer a more granular view of a trading session than the headline index number alone. The PSE also maintains sectoral indices covering financials, industrial, holding firms, property, services, mining and oil stocks.

The exchange was formed in 1992 through the unification of two of the country's oldest securities markets: the Manila Stock Exchange, established in 1927, and the Makati Stock Exchange, established in 1963. It is headquartered in the Bonifacio Global City business district in Taguig City, Metro Manila, and conducts trading sessions on weekdays.

The full rundown of PSEi member stock performance for October 1, 2026 is available on BusinessWorld Online. Because the feature recurs with each trading day, successive editions let readers follow how individual constituents move relative to the benchmark over time.
