Ahead of Market: 10 things that will decide stock market action on Tuesday

Indian markets opened the week weak amid profit booking and caution over US-Iran tensions, with the Nifty slipping below the 50 EMA on hourly charts. Technical analyst Rupak De flagged 23,800 as key support and 24,200 as resistance, while noting elevated volatility ahead of Tuesday's NSE monthly expiry. Defensive sectors such as pharma and healthcare outperformed, while a moderation in FII outflows coupled with normalisation of global AI-driven exuberance could act as incremental triggers for improved sentiment.
