Dealers said investors temporarily relegated to the backseat political concerns after impeachment motions against President Gloria Arroyo were thrown out by the House of Representatives justice committee on Wednesday.
Investors are more focused with the Supreme Courts decision, expected later Thursday or early Friday, on the expanded Value Added Tax (EVAT) law. The court issued an injunction on the law shortly after it came into effect in July after its constitutionality was questioned.
"The impeachment issue is over. So lets move forward," said Nestor Aguila of DA Market Securities.
"One thing is for sure, investors do not want uncertainties. Without the impeachment issue, we would have been focused on more important issues affecting the economy," added Ron Rodrigo of Accord Capital Equities.
"Investors seem to be taking a bet that the TRO (temporary restraining order against EVAT) would be lifted, while others prefer to wait," he said.
The VAT law is considered the centerpiece of the governments economic reform agenda and has been described as crucial in efforts to narrow a chronic budget deficit.
