In a text message, Philstocks Financial, Inc. assistant manager for research and online engagement Claire Alviar said the negative sentiment overseas influenced the trading session as investors digest the inflation data in many countries, raising fears of higher interest rates.

"In the US, increasing bond yields also weighed on sentiment," she said.
