Sensex Surges on Expiry Day as CAS Chaos Sees Nifty Close Flat Amid Market Divergence​

The Indian stock market presented a tale of two indices on Thursday, showcasing significant divergence following the conclusion of the closing auction session (CAS). While the Sensex rallied sharply on expiry day, Nifty 50 managed only a marginal gain, highlighting the complexity and sectoral differences within the benchmark indices.

CAS Divergence: Sensex Rallies as Nifty Holds Steady​

The BSE Sensex experienced robust gains, climbing nearly 374 points to settle at 78,955 on Thursday. In stark contrast, Nifty 50 closed almost flat, registering a modest gain of just 11 points and finishing at 24,636.

Market breadth showed a slight tilt towards bearishness across the National Stock Exchange (NSE), recording 1,668 advances against 1,672 declines. Additionally, 138 stocks remained unchanged during the trading session.

Key Sectoral Performance and Market Drivers​

The sector landscape displayed varied fortunes. The Nifty PSU Bank index showed considerable strength, rallying over 2%. However, the Auto and Realty sectors both experienced downturns, with both indexes falling by more than 1% each.

At the stock level, Reliance Industries (RIL) and State Bank of India (SBI) led the ascent on the Sensex, with both stocks gaining more than 3%. Conversely, Power Grid shares became a laggard, dropping approximately 4% within the benchmark index. The Nifty Midcap 100 saw a slip into the red, falling by over 0.4%, while the Nifty Smallcap 100 closed around 0.5% higher.

Analyst View: Outlook Post RBI Policy and FII Trends​

Geojit Investments Chief Investment Strategist VK Vijayakumar noted that the market trend was not significantly influenced by the RBI’s August monetary policy, which maintained expected lines. He pointed out that the central bank's brief message suggests that a rate hike is not imminent, thus lessening immediate interest rate concerns for certain sectors.

Vijayakumar further elaborated that while financials and automobiles are performing well due to fundamental strength and buoyant demand conditions, strong sectors like pharmaceuticals and telecom have also reported positive results. He advised that sustained, large-scale Foreign Institutional Investor (FII) inflows appear unlikely given continued high US bond yields.

Technical Perspective on Nifty’s Near-Term Movement​

Anand James, Chief Market Strategist at Geojit Investments, provided a technical perspective on the Nifty 50, noting that its key supports remain largely intact despite consolidation and inherent weakness. He suggested this stability improves the odds of a strong upward push for the index in the near future.

James added that while breaching 24,775 remains a target level, achieving a rise above 24,650 could signal an early entry into a potential breakout move. However, he also cautioned that downside markers are being pushed toward 24,550 for the day.

Global Context: Peace Hopes Amid Ongoing Conflict​

In related global news, US President Donald Trump made positive statements regarding peace negotiations with Iran. During an interview, he stated that talks seemed to be progressing very well and suggested a commitment to avoiding escalation. These remarks come as the Middle East conflict enters its sixth month without a permanent resolution being achieved by all involved parties.
