The key 30-stock index reached a low of 1,592 points in early trade as the local market reacted to strong US job growth.
While good for the US economy, this is bad news for emerging markets like Malaysia, as it could raise borrowing costs and strengthen the dollar.
YTL Power International, YTL Corporation and Petronas Dagangan were among the losers which dragged the key index lower.
Meanwhile, Bitcoin was trading sideways at RM428,776, in the run-up to US President-elect Donald Trump's inauguration.
A Trump presidency is expected to turn the US into a global leader in cryptocurrency innovation and promote crypto adoption through executive action.
Both Ethereum and Solana were also trading sideways, with Ethereum at RM14,907 and Solana at RM854.
