The main stock index ended a three-day winning streak to extend losses on the bourse, which is down 12% in the year to date. The index closed at 27,574 points.
Analysts said the market was prone to profit-taking following recent gains, although confidence was improving.
The index has posted a lacklustre performance so far this year as investors await for policy signals that could lift economic growth, which is stuck in low gear after the country emerged from a recession two years ago.
