NIFTY50, SENSEX and the overall Indian stock market performance in the first half of 2026 were heavily dictated by multiple events. NIFTY50 and SENSEX are down 8.6% and 10.2% as of June 30, 2026, amid several global and domestic headwinds.
The first half of 2026 saw US trade tariffs that disrupted the global supply chain, followed by the US-Israel-Iran war. Military action in the Middle East region impacted the crude oil supplies. As a result, crude oil prices surged to record high levels. Meanwhile, AI and AI-related stocks grab investors’ attention, especially in the US and South Korean markets, despite several headwinds.
In the domestic markets, record FIIs sell-off, decline in traditional IT stocks due to AI demand, rupee depreciation and crude oil spike made investors’ sentiments weak.
Despite these headwinds, some of the stocks went against the tide and delivered strong returns to their investors.
Here is a list of 10 stocks which delivered a return of 100% and above in the first half of 2026:
| Stock | Industry | Market cap | YTD return* |

Telecom infrastructure stocks outperformance

Both companies reported strong order books and improved financial performance.

In FY26, Park Medi World’s revenue rose 20.4% YoY to ₹1,679 crore, while net profit jumped 28.6% YoY to ₹274 crore.
