Bursa Malaysia closed lower on Wednesday as traders continued to book profits following a recent upward trend.
The sell-off was compounded by rising crude oil prices and persistent geopolitical tensions in the Middle East, which dampened investor sentiment across the board.
The decline marks a continuation of the profit-taking phase that began earlier in the week.
Banking and oil and gas counters led the decline, reversing some of the momentum that had lifted the index in previous sessions.
The broad-based weakness suggests that investors are cautious about extending gains amid uncertain external conditions.
Elevated energy costs remain a key headwind for the Malaysian market, impacting both consumer spending and corporate margins.
