Following Tuesday's strong performance, the country's benchmark index had succumbed to profit-taking, seeing all its gains erased over the course of the week.
At 12.30pm, the index was down 6.44 points to 1,573.46, slightly below the 200-day SMA, which has served as a crucial support since the market slumped in early May amid an escalation of new coronavirus cases.
The local equities market has been under some selling pressure as developments on the local political scene this week sparked some anxiety.
However, investor sentiment has been on the uptrend in global markets, spurred on by a rally on Wall Street as economic data showed manageable inflation levels in the world's biggest economy.
"We reckon the positive sentiment on Wall Street coupled with the climbing vaccination rate in the country should move local stocks higher," said Malacca Securities Research in its daily outlook.

On the broader market, top actives were Dnex up 3.5 sen to 89 sen, Itronic gaining 3.5 sen to 21.5 sen and Avi rising 4.5 sen to 15.5 sen.
