Stock Market 15 October: Sensex Skyrockets in a Powerful Comeback

Introduction

After two straight sessions of weakness, Dalal Street made a powerful comeback on Wednesday, 15 October 2025. The Stock Market 15 October opened with a strong gap-up and held firm throughout the session, led by renewed optimism in global markets and robust earnings from domestic heavyweights.

This rebound came as a welcome relief for investors who had seen volatility wipe out short-term gains in the previous sessions. Encouraged by easing global bond yields, a firm rupee, and improving risk appetite, both the Sensex and Nifty 50 surged more than 0.7%.

The Stock Market 15 October wasn’t just about index recovery — it was a broad-based rally that saw participation from IT, PSU banks, autos, and midcap counters. With strong quarterly numbers flowing in and foreign investors returning to the buying desk, sentiment shifted firmly in favor of the bulls.

Let’s break down how the Indian market performed, which stocks stood out, and why the Stock Market Today found its strength again.

S&P BSE SmallCap	53,064.84	+421.12	0.80%

The Stock Market 15 October witnessed a broad-based recovery, with every major sector finishing in the green. The Nifty 50 reclaimed the 25,300 mark while the Sensex closed above 82,600, snapping its two-day losing streak.

The rally was not just limited to largecaps — broader markets outperformed as well. The BSE SmallCap index gained over 1% intraday, showing that domestic investor enthusiasm remains strong.

Top Gainers — Stock Market 15 October

The day clearly belonged to ICICI Lombard, Bank of Maharashtra, and Persistent Systems, each posting solid earnings-led moves. Let’s explore the top performers one by one 👇

1️⃣ ICICI Lombard General Insurance — The Star of the Day (+8.92%)

• LTP: ₹2020.3
• Reason: Q2 estimates beat, strong underwriting, premium growth, and operational efficiency.

ICICI Lombard soared nearly 9% as investors applauded its stellar Q2 performance. The insurer reported a sharp improvement in its combined ratio and healthy growth in gross written premiums. The management’s commentary on maintaining underwriting discipline while expanding its retail book further boosted confidence.

This rally also marked a new 52-week high, with trading volumes more than doubling compared to the 20-day average. Analysts believe the insurer’s performance reflects the broader strength in the non-life insurance segment as demand for motor and health insurance rises.

2️⃣ Bank of Maharashtra — PSU Power in Action (+7.6%)

• LTP: ₹59.3
• Reason: Operational strength, asset quality improvement, and 52-week high breakout.

The Bank of Maharashtra surged nearly 8%, continuing its strong run in 2025. Despite a marginal miss in estimates, investors celebrated the bank’s improved NIMs, loan growth, and stable asset quality.

The counter hit a fresh 52-week high as PSU banks remained in focus after a period of consolidation. Heavy trading volumes and buying from institutional desks reflected faith in the bank’s strong credit growth story.

With PSU banks delivering consistent improvement in balance sheets and profitability, this sector is once again emerging as a solid performer in the Stock Market Today.

3️⃣ Persistent Systems — Tech Resilience Shines (+7.24%)

• LTP: ₹5724.6
• Reason: Results beat, margin improvement, and strong deal pipeline.

Persistent Systems continued its winning streak as the company posted a strong set of Q2 results. The IT major delivered better-than-expected margins and reaffirmed guidance for double-digit revenue growth for FY26.

The street also reacted positively to management’s comment about strong client demand from BFSI and healthcare verticals. With global IT peers showing early signs of recovery, midcap IT names like Persistent are regaining leadership in the Stock Market 15 October rally.

4️⃣ Motherson Sumi Wiring — Auto Sector Back in Gear (+5.36%)

• LTP: ₹46.41
• Reason: Recovery in auto demand and export traction.

The auto components space had a good day, led by Motherson Sumi Wiring, which jumped over 5%. The stock benefited from steady demand recovery in the passenger vehicle segment and improved export orders from global OEMs.

The company’s diversified portfolio and strong relationships with automakers globally position it well for future growth. Investors are also betting on its expansion into EV components — a key theme for the next growth leg.

5️⃣ CESC Ltd — Powering Up on Strong Results (+5.24%)

• LTP: ₹176.2
• Reason: Results-led buying; steady earnings and dividend outlook.

Power utility CESC gained over 5% after reporting steady quarterly results. The company showcased robust operational metrics, and management commentary pointed toward stable demand in Kolkata and Noida distribution zones.

CESC also declared a dividend, further strengthening investor confidence. With energy demand expected to remain strong, the stock continues to attract value-seeking investors in the Stock Market Today.

Top Losers — Stock Market 15 October

Even on a bullish day, some stocks lost momentum due to profit booking or stock-specific concerns. Let’s look at the biggest laggards.

1️⃣ Tata Investment Corporation — Post-Split Reality Check (–9.08%)

• LTP: ₹941
• Reason: Sharp post-split correction after a massive run-up.

After a strong rally last week on its stock split announcement, Tata Investment saw heavy profit-taking. The stock dropped nearly 9%, marking its biggest single-day fall in months.

Analysts noted that valuations had run ahead of fundamentals, and the correction was expected after such a steep rally. Despite today’s fall, long-term investors continue to view it as a strong proxy for the Tata Group portfolio.

2️⃣ Nuvoco Vistas — Profit Booking Post Results (–5.18%)

• LTP: ₹404.7
• Reason: Results beat, but near-term profit booking.

Cement major Nuvoco Vistas fell despite reporting better-than-expected Q2 results. The market appears to have priced in the good news earlier, leading to mild profit booking.

Analysts remain positive on the company’s long-term fundamentals, citing improving demand from housing and infrastructure sectors. However, near-term margin pressures may keep the stock range-bound.

3️⃣ BLS International — Regulatory Overhang (–4.72%)

• LTP: ₹278.55
• Reason: Regulatory restrictions and operational uncertainty.

BLS International slipped after reports surfaced regarding new regulatory restrictions in one of its key operational regions. The uncertainty dampened investor sentiment, triggering high-volume selling.

However, the company’s diversified service model and ongoing expansion in visa outsourcing continue to provide long-term stability.

4️⃣ C.E. Info Systems (MapmyIndia) — Profit-Taking After Rally (–4.13%)

• LTP: ₹1868.7
• Reason: Heavy profit booking after a sharp 9% rally in the previous session.

After a stellar performance on Monday, C.E. Info Systems witnessed profit booking. Despite short-term volatility, the company remains one of the top digital mapping and geospatial tech players in India.

Analysts suggest that corrections like these are normal after extended rallies and could offer re-entry opportunities for long-term investors.

5️⃣ JK Cement — Margin Pressure Continues (–3.33%)

• LTP: ₹6501
• Reason: Cost headwinds and soft guidance.

JK Cement came under pressure following margin contraction concerns in its Q2 results. While the company’s revenue growth remained steady, rising fuel and freight costs impacted profitability.

The stock saw mild selling, but analysts believe sustained infrastructure demand could support a rebound in the coming quarters.

Gainers vs Losers Summary

Top Gainers	% Change	Top Losers	% Change
ICICI Lombard	+8.92%	Tata Investment	-9.08%
Bank of Maharashtra	+7.60%	Nuvoco Vistas	-5.18%
Persistent Systems	+7.24%	BLS International	-4.72%
Motherson Sumi Wiring	+5.36%	C.E. Info Systems	-4.13%
CESC	+5.24%	JK Cement	-3.33%

Why the Market Is Up Today

The Stock Market 15 October rally was driven by a confluence of positive global cues and domestic tailwinds. Let’s decode the five major reasons behind the market’s sharp rebound 👇

1️⃣ Global Markets Rebound on Fed Optimism

Asian and European markets traded higher as investors priced in a 75% probability of a U.S. Fed rate cut in the upcoming policy. Global bond yields cooled off, and risk assets gained momentum. This positive sentiment spilled over to Indian equities, boosting early buying interest.

2️⃣ FII Buying Returns After a Gap

After continuous outflows in the past two weeks, foreign institutional investors (FIIs) turned net buyers on Monday. Improved global liquidity and attractive valuations in midcaps encouraged foreign funds to re-enter the market.

This renewed FII participation gave the Stock Market Today much-needed support and improved overall liquidity conditions.

3️⃣ Robust Q2 Earnings Kick In

The earnings season is off to a strong start. Companies like ICICI Lombard, Persistent Systems, and CESC reported solid numbers, which lifted confidence across sectors. Analysts expect double-digit corporate earnings growth for Q2FY26, helping sustain investor optimism.

4️⃣ Stable Rupee & Softening Crude Prices

The Indian rupee stabilized near 83.15 per dollar, aided by RBI’s intervention and FII inflows. At the same time, Brent crude hovered near $83 per barrel, easing inflation concerns and supporting macros.

A combination of lower energy prices and a steady currency creates a favorable environment for equities — especially import-heavy sectors like FMCG and IT.

5️⃣ Domestic Liquidity and Retail Participation

Domestic mutual funds and retail investors continued to buy aggressively during the recent dip. SIP inflows hit a new monthly record, showing strong retail conviction in Indian equities.

This undercurrent of liquidity ensures that any correction remains short-lived — making the Stock Market 15 October rebound both sustainable and healthy.

Conclusion: Bulls Back in Control, but Stay Cautious

The Stock Market 15 October session marked a decisive turnaround for Indian equities. Backed by strong corporate earnings, stable macros, and global tailwinds, the market showed that underlying momentum remains intact.

However, traders should remain cautious as volatility may persist ahead of key global events like the U.S. Fed’s next policy meet and upcoming India CPI data.

For long-term investors, this dip-and-rebound cycle reaffirms that the Indian stock market continues to be one of the most resilient in the world — supported by strong domestic demand, government capex, and steady institutional participation.

If the earnings season continues on this positive trajectory, the Stock Market Today may well be on its way to new record highs before Diwali.

So while the bears lick their wounds, the bulls are clearly back in charge — and for now, it’s a green glow across Dalal Street.
