They said the positive momentum took the index above the psychological barrier of 2,600 points.
The composite index rose 20.26 points to 2,617.41 after moving between 2,620.95 and 2,602.54.
It was the index’s highest close since July 5, 1999 when it ended at 2,621.67 points.

Gainers led losers 76 to 28 with 61 unchanged.
Turnover totalled 1.63 billion shares worth P2.38 billion.
"The momentum carried us above the 2,600-point level and this positive sentiment may spill over to next week," said Rommel Macapagal of Westlink Global Equities.
"There is anticipation over the release of corporate third-quarter results later this month. The record-breaking close of Wall Street also lifted the index," he added.
"Clearly there is momentum and money is flowing into the market, particularly in companies that are expected to report strong earnings for the third quarter," said Mark Alan Canizares of CitisecOnline.
Philippine Long Distance Telephone Co. (PLDT), the most briskly traded stock, rose P20 to close at P2,285.
