Sector Divergence: Pharma Gains as Gold Tumbles
AdThe pharmaceutical sector was a notable bright spot, outperforming the wider market.

The potential value of the transaction exceeds $1.53 billion.

Global Headwinds Weigh on Sentiment
The soft open in Hong Kong was largely attributed to a sell-off on Wall Street.

Spot gold also registered a significant decline of 2.48%, adding to the risk-off mood.
