IT stocks drag indices while banking holds firm
Indian equity benchmarks closed modestly lower on Wednesday, as declines in IT and Tata Group stocks offset gains in banking shares.
The NIFTY 50 ended the session at 24,436, down 0.15%, while the SENSEX settled at 77,966, a fall of 0.24%. The selling was concentrated in the IT sector, where the NIFTY IT index fell 1.54%, with TCS among the notable losers on the day. Tata Group stocks also faced broader pressure following news of N. Chandrasekaran's resignation, which weighed on sentiment across that conglomerate. Rising crude oil prices added to investor caution, given their implications for India's import bill and inflation.
On the other side of the ledger, NIFTY Bank rose 0.77%, with PSU banks cited as outperformers. India VIX, a gauge of expected near-term volatility in the options market, eased 1.58% to close at 11.67, suggesting that overall fear levels in the market remained contained despite the day's negative headline moves. Foreign institutional investors (FIIs) were net sellers in the cash segment, recording an outflow of approximately ₹1,003 crore, while domestic institutional investors (DIIs) provided a substantial offset with net purchases of around ₹5,842 crore.
US inflation data and crude in focus
- US CPI data. Markets globally were positioned cautiously ahead of the US July inflation (CPI) data, which was awaited as a key input for the Federal Reserve's next policy steps. Indian government bonds and the rupee both reflected this wait-and-watch mood through the session.
- US equity futures. Reports indicated that S&P 500 and Nasdaq futures were pointing higher ahead of the US open on Wednesday, supported by earnings results and anticipation around the inflation print. The US cash session had not begun at the time Indian markets closed.
- Brent crude oil. Brent crude was priced at US$88.56 per barrel, edging down 0.39% on the day, though renewed Middle East geopolitical tensions were noted as an underlying factor keeping energy markets on alert and contributing to inflation concerns globally.
- Gold. Gold on COMEX rose 2.39% to US$4,488 per troy ounce, equivalent to approximately ₹1,37,710 per 10 grams, as geopolitical uncertainty and caution ahead of US inflation data supported demand for the metal.
- Euro zone bonds. European government bond yields dipped modestly as investors moved cautiously ahead of the US CPI release, with energy stocks leading European equity markets while broader indices traded largely flat amid mixed earnings and geopolitical risks.
- Indian rupee. The rupee closed at 95.44 against the US dollar, firming slightly by 0.15% on the day, supported in part by Reserve Bank of India intervention in the currency market, even as broader global uncertainty kept traders watchful.
How opening and closing auctions work on Indian stock exchanges
Every trading day on the NSE and BSE, prices do not simply switch on and off like a light. Instead, the exchanges run structured auction sessions at the start and end of the day to arrive at orderly, fair prices. Understanding these mechanisms helps investors make sense of the numbers they read about each evening.
The closing auction session is what determines the official closing price you see published each day — including today's NIFTY 50 close of 24,436.
The day begins with the Pre-Open Session, which runs from 9:00 am to 9:15 am IST. During the first eight minutes (9:00 to 9:08 am), participants can place, modify, or cancel orders, but no trades are executed. This is a pure order-collection window. The exchange then computes an equilibrium price — called the Indicative Equilibrium Price or IEP — which is the price at which the maximum volume of shares can be matched. Between 9:08 and 9:12 am, order matching occurs at this IEP. The final few minutes serve as a transition buffer before regular trading begins at 9:15 am. The purpose of this opening auction is to absorb overnight news — earnings results, global events, policy announcements — in a controlled way rather than letting a flood of orders cause chaotic price swings the moment the market opens.
The Closing Session works similarly but in reverse. Regular trading on the exchanges ends at 3:30 pm IST. From 3:30 to 3:40 pm, a closing auction call session runs, during which orders are collected and then matched to arrive at the official closing price. This price is calculated as the volume-weighted average price (VWAP) of trades executed in the last 30 minutes of the regular session, or through the call auction mechanism — the exact method can vary by exchange and security type, but the principle is the same: a transparent, rules-based process rather than the price of the very last trade, which could be a small or unrepresentative transaction. The closing price that results from this process is what gets reported in the news, used to calculate index levels, and referenced for settlement of derivatives contracts. Today's NIFTY 50 closing level of 24,436 and SENSEX at 77,966 are both products of this closing auction mechanism, making it a foundational part of how Indian market data is produced each day.
