BusinessWorld has published its daily recap of how member stocks of the Philippine Stock Exchange index (PSEi) fared in Thursday's trading session, September 17, 2026.

The PSEi is the benchmark stock index of the Philippine Stock Exchange (PSE), the national stock exchange of the Philippines. It tracks the performance of 30 listed companies that serve as its constituent "member stocks," drawn from major sectors of the local economy, including holding firms, banks, property developers, telecommunications providers, utilities, and consumer businesses. As the most widely referenced gauge of Philippine equities, the index and its members are closely monitored by investors, analysts, and market watchers each trading day. While the index level condenses a session into a single figure, it does not show how each individual member moved — which is where stock-by-stock breakdowns come in.

BusinessWorld's recurring "How PSEi member stocks performed" feature offers a per-stock rundown of the session, giving readers a quick reference on how each index constituent moved during the day's trade on the PSE, with a fresh installment published for each trading day. Because those constituents cut across the economy's major sectors, rundown also lets readers compare how different segments of the local market fared within the same session.

The full stock-by-stock recap for the September 17, 2026 session can be found in the original report on BusinessWorld Online: How PSEi member stocks performed — September 17, 2026
