Sensex and Nifty Performance Overview

The BSE Sensex opened flat with a slight dip of 41.32 points but recovered to trade at 84,671.10, marking a gain of 111.45 points or 0.13% by mid-session. This level places the Sensex approximately 1.76% below its 52-week high of 86,159.02, indicating that the benchmark index remains within striking distance of its recent peak. The index is trading above its 50-day moving average (DMA), which itself is positioned above the 200 DMA, signalling a sustained medium-term upward trend.

The Nifty index mirrored this cautious optimism, with large-cap stocks driving the momentum. Midcap and small-cap indices showed more muted activity, with the BSE Midcap rising by 0.13% and the Smallcap index declining by 0.27%, suggesting a preference for established companies amid current market conditions.

Sectoral Trends: IT Leads While Auto Faces Pressure

Out of 38 sectors tracked on the BSE, 16 advanced while 22 declined, reflecting a mixed breadth across the market. The Information Technology sector emerged as the top gainer, rising by 0.87%, buoyed by select large-cap IT stocks that attracted buying interest. Conversely, the automobile sector faced headwinds, with the NIFTYAUTO index falling by 1.03%, weighed down by concerns over demand and input costs.

Other sectors showed varied performances, with defensive sectors maintaining stability while cyclical sectors experienced volatility. This divergence highlights the cautious stance of investors amid ongoing global economic uncertainties and domestic policy developments.

Market Breadth and Capitalisation Trends

The advance-decline ratio across the BSE 500 stood at 208 advances against 290 declines, resulting in a ratio of 0.72x. This indicates that more stocks declined than advanced, despite the modest gains in headline indices. Large-cap stocks led the market, with the BSE 100 index rising by 0.17%, while midcaps showed a smaller gain of 0.13%. Small caps, however, lagged with a decline of 0.27%, reflecting selective investor interest and risk aversion in smaller companies.

Top Gainers and Losers Across Market Caps

Among the BSE 500 stocks, HDFC AMC led the gainers with a rise of 5.49%, reflecting renewed investor interest in asset management companies amid stable inflows. Crompton Greaves Consumer Electricals followed closely with a 5.15% increase, supported by positive demand outlook in the consumer electrical segment. Hindustan Copper also featured among the top performers, advancing by 5.05%, possibly benefiting from commodity price movements and government support for mining activities.

On the downside, PTC Industries declined by 4.71%, impacted by sector-specific challenges and profit booking. Siemens Energy India fell by 4.56%, reflecting cautious sentiment in the energy equipment space. Ola Electric dropped 3.86%, amid concerns over the electric vehicle sector’s near-term growth prospects.

Breaking down by market capitalisation, Antony Waste Handling emerged as the top small-cap gainer with a notable 14.56% rise, indicating selective buying in niche environmental services. Conversely, Vishnu Prakash R declined by 6.58%, marking the steepest fall among small caps. In the midcap segment, Crompton Greaves Consumer Electricals led gains, while GE Vernova Transmission & Distribution recorded a 5.16% decline. Among large caps, Indian Oil Corporation (IOCL) was the biggest laggard, down 3.48%, pressured by refining margins and crude price fluctuations.

Foreign Institutional and Domestic Investor Activity

Foreign Institutional Investors (FIIs) and Domestic Institutional Investors (DIIs) activity remained subdued, with no significant net inflows or outflows reported during the session. This restrained participation contributed to the cautious market tone, as investors await clarity on global economic cues and domestic corporate earnings.

Global markets showed mixed signals, with US and European indices fluctuating amid ongoing concerns over inflation and central bank policies. Asian markets were similarly volatile, reflecting investor caution ahead of key economic data releases. These external factors continue to influence Indian market sentiment, underscoring the interconnectedness of global financial conditions.

Technical Indicators and Market Outlook

The Sensex’s position above its 50 DMA, with the 50 DMA itself above the 200 DMA, suggests that the medium-term technical trend remains intact. This alignment often signals a constructive market environment, although the modest gains and breadth below 1 indicate that momentum is not broad-based. Investors may continue to favour large-cap stocks with stable earnings and strong balance sheets, while exercising caution on smaller and mid-sized companies facing sector-specific headwinds.

Upcoming corporate earnings announcements, such as Sudeep Pharma’s results scheduled for 19 Dec 2025, will be closely watched for cues on sectoral performance and broader economic recovery. Market participants are likely to remain attentive to global developments, including central bank decisions and geopolitical events, which could influence risk appetite in the near term.

Summary

In summary, the Indian equity market on 18 Dec 2025 exhibited a measured advance led by large-cap stocks, with the Sensex gaining 0.13% to trade at 84,671.10. Sector performances were mixed, with IT showing strength and the automobile sector under pressure. Market breadth was subdued, reflecting selective buying amid cautious investor sentiment. Foreign and domestic institutional activity remained balanced, while global cues continued to shape market dynamics. Investors may find opportunities in fundamentally strong large caps such as HDFC AMC and Crompton Greaves Consumer Electricals, while monitoring developments in mid and small caps for potential volatility.
