The BSE Sensex rose 484.53 points (0.58%) to close at 83,952.19, recovering smartly after a weak start on Friday, October 17, 2025. The index touched an intraday high of 84,172.24 and a low of 83,206.08. Similarly, the NSE Nifty 50 climbed 124.55 points (0.49%) to settle at 25,709.85. During the day, it hit a high of 25,781.50 and a low of 25,508.60.

Market sentiment improved following upbeat global cues and renewed investor confidence in large-cap stocks. "FIIs continued to be net cash sellers to the tune of Rs. 895.74  crore as of Oct’25," said Shrikant Chouhan, Head Equity Research, Kotak Securities.

Both benchmarks have stayed near their record highs, with the Sensex just below its 52-week peak of 84,172.24 and the Nifty close to its lifetime high of 25,781.50, signalling continued strength in the broader market.

Ponmudi R, CEO of Enrich Money, a SEBI-registered online trading and wealth tech firm, said, "The Indian markets ended the week on a strong footing, with both the Nifty 50 and Bank Nifty surging past their key psychological resistance levels amid sustained institutional participation and broad-based buying interest. Despite a mixed global backdrop, domestic sentiment remained firm, supported by strength in financials, autos, and FMCG stocks."

"On the technical front, the Nifty 50 has confirmed a breakout above the horizontal resistance line near 25,700, signalling continuation of the prevailing uptrend. The index touched a new 52-week high at 25,781.50, and the next immediate resistance is placed around 25,800–26,000. A decisive breakout above this zone could open the next leg of the rally toward 26,300, setting up new lifetime highs. On the downside, strong support is visible around 25,600–25,450, which aligns with the rising trendline and short-term moving averages," said Ponmudi R.

The open interest (OI) data of Nifty options validates the bullish structure. Total Put OI stands at 17.2 crore, while Call OI is around 21.3 crore, suggesting mild profit booking at higher levels. Put writers are active at 25,600 and 25,500, establishing a strong base, while Call writing concentration at 25,800–26,000 highlights the next resistance zone. The Put-Call Ratio (PCR) at 0.81 reflects a balanced sentiment, indicating the market may consolidate briefly before resuming its upward trajectory.

The Bank Nifty outperformed, delivering a clear breakout to record a new lifetime high of 57,830, closing comfortably above its previous peak of 57,650. Ponmudi R said, "The index is now approaching resistance at 58,000–58,300, where further profit-booking could emerge in the short term. A sustained move above 58,300 may push the index toward 59,000, while immediate support is seen around 57,500–57,250. A break below 56,500 could trigger mild consolidation, though the broader trend remains firmly positive."
