Stocks Making the Biggest Moves Midday: Shakti Pumps, Enviro Infra, IRB Infra, Ather Energy, ESDS and More

Shakti Pumps and ESDS Software Solution led the midday action on September 10, while Ather Energy and IRB Infrastructure Developers also gained. Crude oil prices moving above $100 a barrel remained a key factor influencing investor sentiment across sectors.

The domestic equity market traded on a subdued note by midday on September 10, with the Nifty 50 hovering around 23,460 and the BSE Sensex above 74,850.

The market remained sensitive to the rise in crude oil prices, with Brent crude moving above the $100-a-barrel mark amid concerns over potential supply disruptions in the Middle East. While higher crude prices can benefit upstream oil producers, they can increase input and operating costs for sectors such as aviation, tyres and paints.

At the same time, several stocks recorded notable movements on the back of company-specific developments, including new orders, operating updates and product launches.

Here are the major stocks and sectors in focus at midday.

Infrastructure Stocks

Enviro Infra Engineers Share Price

Enviro Infra Engineers share price was trading 1.88% higher by midday after its step-down subsidiary Suyog Urja received a ₹224.19 crore Letter of Intent (LoI) from Tata Power Renewable Energy.

The order is for EPC turnkey work on a 180 MW NTPC wind power project at Parli, Maharashtra.

The scope of the project includes the construction of foundations for 58 wind turbine generators, balance-of-plant work, a storage yard, access roads and a 33 kV transmission line.

Execution of the project is scheduled to be completed by March 31, 2027.

The order places the company in focus amid continued investments in India’s renewable-energy and power infrastructure.

IRB Infrastructure Developers Share Price

IRB Infrastructure Developers share price was up 2.83% by midday after the company reported a 25% year-on-year increase in toll revenue for August.

Toll revenue rose to ₹807 crore in August 2026, compared with ₹646 crore in August 2025.

Among the key contributors, IRB MP Expressway generated ₹172 crore, while IRB Golconda Expressway and IRB Ahmedabad Vadodara Super Express Tollway contributed ₹88 crore and ₹80 crore, respectively.

The improvement in toll collections provides an important operating indicator for the company’s road-infrastructure portfolio.

Shakti Pumps Share Price

Shakti Pumps (India) Ltd. was among the biggest gainers in the market, with its share price rising 9.43% by midday.

The stock gained after the company disclosed a ₹235.92 crore order from Maharashtra State Electricity Distribution Company (MSEDCL) for 10,000 off-grid solar photovoltaic water pumping systems.

The order covers 3 HP, 5 HP and 7.5 HP pumps under the Magel Tyala Saur Krushi Pump Yojana.

The contract includes the supply, transportation, installation, testing and commissioning of the solar pumping systems. The company is expected to execute the order within 60 days.

The order is also significant in relation to the company’s financial performance. Its value is equivalent to approximately 27% of Shakti Pumps’ consolidated revenue of ₹858.67 crore reported for the April-June quarter of FY27.

The order therefore puts the stock firmly in focus among renewable-energy and solar-infrastructure plays.

Ather Energy Share Price

Ather Energy share price gained 4.3% by midday, with investors continuing to track the company’s product pipeline and growth prospects.

Market attention has remained focused on the company’s new Konarc electric scooter, which was launched in August.

The model is based on Ather’s new EL platform and fifth-generation Bedrock battery pack. The battery comes with a 10-year or 1,00,000-km warranty.

The company’s recent financial performance has also attracted attention. Ather Energy reduced its Q1 FY27 net loss to ₹51.09 crore, compared with a net loss of ₹178.23 crore in the corresponding period a year earlier.

At the same time, its revenue increased by nearly 89% year-on-year.

The combination of improving financial performance and new product launches remains a key factor for investors tracking the electric two-wheeler segment.

Oil Producers

Oil producers were among the beneficiaries of the rise in crude prices.

Oil and Natural Gas Corporation (ONGC) share price gained more than 2% by midday, while Oil India also advanced by more than 2%.

The gains came as Brent crude moved above $100 a barrel, with concerns over supply disruptions in the Middle East supporting oil prices.

For upstream oil producers, higher crude prices can support realisations. However, the ultimate impact on earnings also depends on production levels, costs, government policies and other operating factors.

Oil Marketing Companies

Oil marketing companies saw mixed trading.

Indian Oil Corporation share price was nearly flat by midday, while Bharat Petroleum Corporation Ltd. (BPCL) gained 0.26% and Hindustan Petroleum Corporation Ltd. (HPCL) rose 1%.

Investors were assessing the impact of crude prices above the $100-a-barrel level on the refining and marketing businesses.

Higher crude prices can increase input costs for oil marketing companies. If retail fuel prices are not adjusted quickly enough to reflect the increase, refining and marketing margins can come under pressure.

Paint Stocks

Paint stocks came under pressure as higher crude prices raised concerns about input costs.

Asian Paints share price declined 0.55% by midday, while Indigo Paints fell 1.28%.

Crude oil is linked to several petroleum-based raw materials used by the paint industry. A sustained increase in crude prices can therefore increase production costs.

The eventual impact on profitability will depend on companies’ ability to manage costs, improve efficiency and pass higher expenses on through pricing.

Tyre Stocks

The tyre sector also saw mixed trading.

Apollo Tyres share price declined 1.22%, while MRF share price gained 0.32% by midday.

Higher oil prices can increase the cost of synthetic rubber and other petroleum-linked inputs used in tyre manufacturing.

For tyre companies, the impact on margins will depend on the extent of input-cost increases and their ability to offset those pressures through pricing, product mix and cost management.

Aviation Stocks

Aviation stocks remained under pressure as crude oil prices crossed the $100-a-barrel mark.

InterGlobe Aviation share price declined 0.74%, while SpiceJet fell 0.64% by midday.

The development is important for airlines because aviation turbine fuel (ATF) is one of their major operating expenses.

A sustained increase in crude oil prices can therefore translate into higher fuel costs and potentially put pressure on airline operating margins and profitability, particularly if higher costs cannot be passed on to passengers through ticket prices.

Reliance Industries Share Price

Reliance Industries share price faced a mixed impact from the rise in crude prices because of the company’s integrated business model.

Its upstream oil operations can potentially benefit from stronger crude realisations. However, higher feedstock costs can put pressure on its petrochemical operations.

As a result, the overall impact of higher crude prices on Reliance Industries depends on the performance of its various businesses, including refining and petrochemicals, as well as prevailing margins.

ESDS Software Solution Share Price

ESDS Software Solution was among the strongest movers of the session, with its share price gaining 10% by midday.

The stock extended its post-listing rally and hit the upper circuit for the second consecutive session at the revised 10% limit.

The stock has risen sharply from its ₹429 IPO issue price since listing, attracting strong market interest following its debut and subsequent upper-circuit sessions.

The continued movement in ESDS Software Solution highlights the heightened investor attention around newly listed stocks, particularly during the initial period following their market debut.

What Investors Should Watch

The midday market action on September 10 highlights how different sectors are responding differently to the same macroeconomic trigger.

While ONGC and Oil India benefited from higher crude prices, sectors such as aviation, paints and tyres faced concerns over rising input costs.

At the individual-stock level, company-specific developments remained important. Shakti Pumps’ ₹235.92 crore solar-pump order, Enviro Infra Engineers’ ₹224.19 crore renewable-energy project order, IRB Infrastructure Developers’ 25% growth in toll revenue and Ather Energy’s improving financial performance were among the key developments supporting investor interest.

Meanwhile, ESDS Software Solution’s 10% gain and continued upper-circuit movement kept the recently listed stock in the spotlight.

For investors, the broader market direction will continue to depend on crude-oil prices, geopolitical developments, domestic market sentiment and upcoming corporate earnings and business updates.
