Bursa Malaysia opened slightly higher on Wednesday with gains limited by emerging profit taking in selected heavyweights, dealers said.

At 9.10am, the benchmark FTSE Bursa Malaysia KLCI (FBM KLCI) eased 0.21 point to 1,643.05, after opening 2.08 points weaker at 1,641.18.

Market breadth was positive with gainers leading losers 172 to 82, with 143 counters unchanged, 1,371 untraded and 12 others suspended.

Turnover stood at 97.10 million shares worth RM49.71 million.

Based on yesterday's close, RHB Retail Research said buyers were retaining control of the market, as the recent low of 1,607.50-point support mentioned previously was not violated.

"On the other hand, we are eyeing the immediate resistance level at 1,673 points, while the next resistance would likely be at the 1,700-point psychological mark.

"Hence, we advise traders to maintain long positions. A stop-loss can be set below the 1,607.50-point mark in order to limit the downside risk," it said in a research note today.
