The main-share Philippine Stock Exchange index tumbled by 129.18 points, or 1.67 percent, to close at 7,610.68, tracking a US and regional downturn.
Global growth concerns escalated as the latest US manufacturing survey for September contracted for the second straight month and showed the worst reading in a decade.
At the local market, the index broke a strong support level at 7,620, which means that the next barrier would be at 7,475, the low seen last May, local stock brokerage Papa Securities said.
