Indian stock markets are poised for a potentially lower opening on Tuesday, December 30, 2025, influenced by global cues and upcoming contract expiries. Asia-Pacific markets followed Wall Street's decline, with technology stocks pausing their rally. Key stocks to watch include Bharat Electronics, which received a ₹569 crore order, and other defense companies benefiting from a ₹79,000 crore procurement approval. Silver prices saw some retreat after reaching a record high. Traders anticipate volatility due to weekly and monthly NSE Nifty contract expiries.
