The first half of 2026 witnessed significant market challenges with NIFTY50 and SENSEX declining 8.6% and 10.2% respectively as of June 30, 2026. According to reports from Upstox, multiple global and domestic headwinds impacted market sentiment, including US trade tariffs that disrupted global supply chains, the US-Israel-Iran war, and record FII sell-off. The market decline was further compounded by rupee depreciation, decline in traditional IT stocks due to AI demand, and crude oil spike following military action in the Middle East that impacted crude oil supplies. However, recent developments show small-cap outperformance with the Russell 2000 delivering approximately 21% returns compared to roughly 10% for the S&P 500, marking a notable shift in leadership following a prolonged period of large-cap dominance. Despite these challenges, the Dow Jones Industrial Average is on pace for its best first half of any year since 2021, climbing 8.9% to top 52,000, while the S&P 500 jumped 9.4% and the tech-heavy Nasdaq soared 12.5% over the same period.
Despite challenging market conditions, several mid-cap stocks delivered exceptional returns to investors. As reported by Upstox, Sterlite Technologies emerged as the top performer with a 494% YTD return, followed by MTAR Technologies at 215% and HFCL Limited at 214%. Other notable performers included Aditya Infotech (144%), Garware Hi-Tech (114%), Acutaas Chemicals (106%), Atlanta Electricals (106%), Rubicon Research (105%), Avalon Technologies (105%), and Park Medi World (104%). These companies span across telecom equipment, precision engineering, electronics manufacturing, pharmaceuticals, and healthcare sectors, with leadership concentrated in investment-linked sectors including industrials and information technology. The stellar performance of AI chipmakers has also driven up markets, with Micron soaring 306% in value this year and Sandisk climbing a staggering 830% over that period, allowing major indexes to overcome a weak year for the 'Magnificent Seven' tech giants.
Sterlite Technologies and HFCL emerged as the standout performers in telecom infrastructure, benefiting from rising investment in AI infrastructure and data centres in India. According to Upstox reports, the companies reported strong financial performance with Sterlite Technologies' consolidated revenue rising 18.8% YoY to ₹4,745 crore and turning profitable with net profit of ₹56 crore compared to a loss of ₹123 crore in FY25. HFCL reported consolidated revenue of ₹4,949 crore (up 21.7% YoY) and net profit of ₹329 crore (90.1% YoY). The 5G network rollout in India increased orders for telecom equipment and optical fibre products, with the ongoing buildout of artificial intelligence infrastructure driving substantial capital spending estimates pointing to hundreds of billions of dollars in annual investment this year.
MTAR Technologies delivered strong returns of 215% benefiting from robust demand in aerospace, defence, clean energy and nuclear sectors. As reported by Upstox, the company reported consolidated revenue from operations of ₹876 crore, up 29.5% YoY, while net profit jumped 75.9% YoY to ₹95 crore. Aditya Infotech and Avalon Technologies gained from rising demand for surveillance systems and electronic manufacturing services respectively. Aditya Infotech reported total revenue rising 35.6% YoY to ₹4,221 crore with net profit at ₹368 crore, while Avalon Technologies posted consolidated revenue of ₹1,603 crore (up 45.9% YoY) and net profit of ₹113 crore. The ongoing buildout of artificial intelligence infrastructure is creating a transmission channel through which smaller companies may participate in the broader theme, with rising market capitalizations potentially leading to inclusion in larger-cap indices.
Park Medi World delivered 104% returns supported by robust FY26 earnings and hospital network expansion. According to Upstox, the company successfully acquired a 100% stake in The Medicity Hospital in Rudrapur for ₹177 crore, expanding its footprint to 17 hospitals. Rubicon Research benefited from rising demand for generic medicines in regulated markets with profit after tax rising 84.3% YoY to ₹247 crore and revenue from operations increasing 36.6% YoY to ₹1,754 crore. Garware Hi-Tech and Acutaas Chemicals delivered strong returns of 114% and 106% respectively due to favourable industry trends and rising demand for speciality products offering higher profit margins than commodity products. The current environment has remained supportive with the labor market adding a robust average of about 114,000 jobs each month from January to May, while a combined measure of business and consumer spending expanded at the start of 2026, with consumer spending accounting for about two-thirds of U.S. economic activity.
