This week, investors also focused on volatile US Treasury yields, which hit their highest level in the past three years, selling pressure in the market, stock and sector-specific actions based on supply chain impact due to higher input cost potential.

Nifty India VIX, i.e., the country’s near-term volatility index, ended flat after a highly volatile session this week, touching a high of 12.12 from a low of 9.25 during the week ended Friday, September 4.

What happened on Friday’s market?

On Friday, the benchmark equity indices ended their four-day losing streak as investors focused on the strong momentum from Asian markets, easing US Treasury yields and major buying support from domestic investors at a time when FIIs have largely kept up their selling streak.

NSE data showed that the NIFTY50 ended 0.10% higher at 23,897.70 points after Friday’s trading session, in comparison to 23,873.45 points at the previous equity market close.

Meanwhile, the BSE SENSEX index closed 0.48% higher at 76,515.43 points after the trading session on September 4, compared to 76,152.86 points at the previous stock market close, according to the exchange data.

Investors were also reacting to SEBI’s latest plans to review the derivative settlement methodology at expiry amid concerns over using the closing auction session (CAS) determined closing price as the settlement basis.

The regulator īs expected to come out with a consultation paper on the proposed framework, likely to be released in about a week.

Top NIFTY50 gainers & losers this week

Coal India, Reliance Industries, Tata Steel, ONGC, and Grasim Industries were the top five weekly gainers on the benchmark NIFTY50 index as of the stock market close on Friday, September 4.

Other stocks like Adani Enterprises, Eicher Motors, Maruti Suzuki India, Mahindra & Mahindra, and Shriram Finance were among the top laggards this week on NSE.

Factors which impacted markets this week

One of the primary global factors that impacted Indian stock market sentiment this week was global crude oil prices surging nearly 9% over the last five sessions to a high of $97.62 per barrel (bbl) due to the escalations between the United States and Iran in West Asia.

United States and Iran restarted their series of attacks against each other this week after a month-long pause in military action, increasing the supply chain risk amid no signs of a potential peace deal in the near-term.

Both sides carried out several missile and drone attacks against strategic military targets in the West Asia region, taking turns to retaliate against each other amid America’s larger plan of economic warfare against Iran.

Data also showed that global benchmark Brent crude oil prices have increased over 20% in the last one-month, and were marginally higher in the last 3-month basis.

Investors were also focused on other major global cues, like the US Treasury yields rallying to their highest levels in the last three years to 4.818%, in turn increasing fears among investors about a US Federal Reserve rate hike in the upcoming September meeting.

However, the yields started easing from their recent high levels as US Fed Governor Christopher Waller said that he is ‘inclined to support’ the key interest rates for the US economy, lowering rate hike fears in the market.

While foreign outflows maintained the pressure on Indian equities, MSCI’s index rebalancing coming into effect from September 1 resulted in major inflows from passive funds and ETFs on specific stocks as they aim to reflect their portfolios to the benchmark indices.

In the domestic market, key factors like the supply chain revival potential among defence stocks, the central government’s domestic gas incentive scheme for low-cost gas, crude oil upstream and downstream impact, along with the Reserve Bank's special USD-INR forex swap facility deadline, moved markets this week.

Investors were also focused on the potential for the upcoming NSE IPO, after several media reports suggested that the stock exchange company received SEBI approval for its ₹30,000 crore public issue.

Which sectors moved the most this week?

NSE data showed that Nifty Oil & Gas up 1.1%, Nifty Private Bank up 0.3%, and Nifty Energy up 0.2% were among the top-gaining sectors for the week ended Friday, September 4, 2026.

While other major sectoral benchmark indices like the Nifty Auto lost 4%, Nifty Consumer Durables declined 2.6%, Nifty Media lost 2.3%, Nifty Healthcare dropped 2.3%, and Nifty FMCG lost 2% this week.

Top midcap stocks this week

Nifty Midcap 100 data showed that stocks like Lenskart Solutions, LIC Housing Finance, IDFC First Bank, Tata Communications, and SBI Cards & Payment Services were the top five gainers this week.

Others like KEI Industries, Polycab India, Havells India, KPIT Technologies, and ICICI Prudential AMC were the top five laggards in the midcap index in the week ended Friday, September 4.

Top smallcap stocks this week

NSE data showed that smallcap stocks like IFCI, Welspun Corp, Capri Global Capital, RBL Bank, and Brigade Enterprises were among the top gainers on the benchmark Nifty Smallcap 100 index as of the week ended Friday, September 4, 2026.

Others like Aarti Industries, Kaynes Technology India, Amara Raja Energy, Swan Corp., and Deepak Fertilisers were among the top laggards this week.

How much have FIIs sold on Friday?

Latest data collected from NSE shows that the foreign institutional investors (FIIs) sold around ₹3,111.94 crore worth of assets from the capital markets in a single day during Friday’s trading session, while domestic buying supported the positive ending.

On September 4, domestic institutional investors (DIIs) purchased a total of ₹8,930.12 crore worth of assets in the capital market across the stock exchanges, as per the exchange data.

NSDL data showed that foreign portfolio investors (FPIs) have sold ₹2,886.18 crore worth of assets across asset classes from the Indian markets in a single day.

Largely, the data showed that so far in September 2026, foreign investors have been net sellers in emerging markets like India due to higher risk sentiment amid the rebound in global crude oil prices and no signs of a peace deal in West Asia.
