Indian stock market witnessed a highly volatile trading week from August 24 to August 28, with the benchmark Sensex and Nifty ending lower from Monday's closing levels despite a strong recovery on Friday. Concerns around global interest rates, crude oil prices, geopolitical developments, foreign fund flows and volatility linked to the newly introduced Closing Auction Session (CAS) kept investors cautious through the week.

Key Highlights

• Stock Market Weekly Report shows Nifty ended 0.18% lower and Sensex 0.14% lower despite Friday's rebound.
• IT stocks led Friday's recovery after Nvidia's results, while HDFC Bank and Reliance Industries weighed on markets.

This weekly report shows the Nifty 50 ended Friday at 24,175.65, gaining 0.35% on the day, while the BSE Sensex closed at 77,264.51, up 0.43%. However, compared with Monday's close, the Nifty remained around 0.18% lower, while the Sensex was down about 0.14% over the five-session period. The broader market was relatively more resilient, with both small-cap and mid-cap indices gaining around 0.5% during the week.

Market Performance: Monday to Friday

Monday: Market Gives Up Early Gains

The week began on a cautious note. Indian stock market initially gained on positive global cues and softer crude prices, but selling pressure emerged later in the session. The Nifty eventually closed at 24,219.05, down 0.14%, while the Sensex declined 171.72 points to 77,369.11. Nearly 2,000 stocks advanced, although more than 2,200 declined, indicating underlying weakness beneath the headline indices.

Tuesday: Recovery Led by Falling Oil and Buying Interest

Markets rebounded sharply on Tuesday as crude oil prices eased to around $89.20 a barrel. The Nifty gained 0.48% to 24,334.55, while the Sensex advanced 286.98 points, or 0.37%, to 77,656.09.

The session was particularly volatile, marking the first monthly derivatives expiry under the new Closing Auction Session mechanism. Financial and IT stocks participated in the recovery, while Hindustan Copper fell 7.2% after the government announced plans to divest up to 6% of its stake at a 10.5% discount.

Wednesday: IT and Reliance Drag the Benchmarks

The market reversed lower on Wednesday despite softer oil prices. The Nifty fell 0.52% to 24,207.75, while the Sensex declined 183.15 points to 77,472.94.

IT stocks were a major drag on the session, with the Nifty IT index falling 1.5%. Investors remained concerned about higher costs arising from proposed US H-1B visa measures, while also awaiting Nvidia's results for clues on the sustainability of global AI spending. Reliance Industries also fell 1.4%, adding further pressure to the benchmarks.

Thursday: Expiry Volatility Triggers Sharp Fall

Thursday was the weakest session of the week. The Nifty declined 0.48% to 24,090.85, while the Sensex dropped 539.35 points, or 0.70%, to 76,933.59.

The sell-off intensified during the monthly derivatives expiry. HDFC Bank was one of the biggest drags, falling 2.2% amid reports of a US class-action lawsuit and uncertainty over CEO Sashidhar Jagdishan's tenure renewal. Eleven of 16 major sectors ended lower on the day.

The sharp price movement during the closing auction also increased scrutiny of the new CAS mechanism, which has been introduced to determine official closing prices for certain futures-eligible stocks.

Friday: IT Rally Helps Markets Recover

Indian equities bounced back on Friday, ending a two-session losing streak. The Nifty rose 0.35% to 24,175.65, while the Sensex gained 0.43% to close at 77,264.51.

The recovery was led primarily by heavyweight IT stocks, following strong global technology sentiment after Nvidia's results. TCS and Tech Mahindra were among the notable gainers, while ICICI Bank and ITC also supported the broader market.

Sector Performance

The week saw significant divergence across sectors. IT stocks recovered strongly on Friday, helped by Nvidia-related optimism, even though the sector had suffered earlier in the week amid concerns around US visa costs and AI-related disruption.

Financial stocks faced pressure from weakness in major private-sector names, particularly HDFC Bank, while Reliance Industries also weighed on the broader indices.

Meanwhile, the small-cap and mid-cap segments remained comparatively resilient, with both indices gaining around 0.5% during the week. Ten of the 16 major sectors declined over the week overall, highlighting the relatively narrow nature of the market's recovery.

Major Factors Driving the Market

1. Closing Auction Session

The new Closing Auction Session emerged as an important market theme through the week, particularly during derivatives expiry. Sharp price movements during the closing period raised concerns around volatility and price discovery. The system will face another major test with the MSCI rebalancing scheduled for August 31, when large institutional orders could increase closing-session activity.

2. Crude Oil Prices

Oil remained an important market driver through the week. Easing crude prices provided relief to Indian equities, given the country's heavy dependence on imported energy. However, geopolitical uncertainty around the Middle East continued to keep investors alert.

3. US Interest Rates and Fed Signals

Investors remained cautious ahead of comments from the US Federal Reserve, with global markets closely focused on interest-rate expectations. The Fed's policy outlook remains particularly important for emerging markets, as changes in US yields can influence foreign investment flows into Indian equities.

4. Foreign Investor Flows

Foreign investor selling remained a structural concern for Indian equities through the week. A recent Reuters poll showed analysts have become more cautious about India's market outlook, as foreign funds redirect capital toward other Asian markets. At the same time, strong domestic SIP flows continued to provide support to Indian stocks.

Weekly Outlook

The stock market today recovered an will enter the next week with a cautious and range-bound bias. The Friday recovery is encouraging, particularly given the renewed momentum in IT stocks, but the Nifty remains below the 24,300-24,350 zone that has acted as an important near-term hurdle.

Investors will closely watch MSCI's August 31 rebalancing, foreign institutional flows, crude oil prices, the rupee, US Federal Reserve commentary, global technology stocks, and the performance of HDFC Bank and Reliance Industries in the coming week.

Overall, the week demonstrated that domestic equities remain vulnerable to global macroeconomic and geopolitical developments, while strong domestic liquidity and selective buying continue to cushion the broader market. The next week could therefore remain volatile, with sector-specific opportunities emerging even as the headline indices struggle for a sustained upward move.
