MANILA, Philippines -- Share prices will likely continue their downturn in the week ahead amid high oil prices and renewed fears over other commodity prices and US inflation, dealers said.

The fall of the Philippine index through the 2,500-point support level on Friday may be the start of a sharp slide, warned Jose Vistan of AB Capital Securities Inc.

"We broke several important support levels and we don't see much support for now. From a technical standpoint, we don't know where the next support levels would be," he said.

For the week to June 27, the composite index fell by 112.28 points or 4.35 percent to 2,466.29.

Average daily turnover rose to P3.078 billion ($68.8 million) from P2.378 billion in the previous week.
