Shares of prominent Indian defence sector companies, MTAR Technologies and Data Patterns, experienced significant declines of up to 11% in trading today, May 15, 2026, even as the broader market saw a rally. Investor activity, including profit booking and reactions to quarterly earnings, appears to be the primary driver behind these movements.
MTAR Technologies Sees Profit Booking After Recent Gains
MTAR Technologies' stock slipped 5.33% to Rs 7167.20 today, down from its previous close of Rs 7570.90. This correction follows a substantial 10% rally in the prior session, which saw the stock hit a 52-week high of Rs 7727.85 on May 14, 2026. The recent surge was fueled by a significant Rs 2278.96 crore order win from an international client. The market capitalization of MTAR Technologies currently stands at approximately Rs 22,100 crore.
Despite today's dip, MTAR Technologies has demonstrated strong performance recently, with its stock rising 100% in the last three months. The company, known for its contributions to the Clean Energy, Space, and Defence sectors, maintains nine manufacturing units, including an export-oriented unit in Hyderabad.
Data Patterns Shares Fall Following Q4 Revenue Decline
Data Patterns, another key player in the defence electronics sector, saw its shares fall more sharply, dropping 11% to Rs 3566 against a previous close of Rs 4009. This decline came in the wake of the company's fourth-quarter (Q4 FY26) earnings report, which revealed a 13% year-over-year slip in revenue to Rs 344.9 crore, compared to Rs 396.2 crore in the same period last fiscal year.
While the revenue decline impacted investor sentiment, Data Patterns did report a 21% rise in profit after tax (PAT) for Q4 FY26, reaching Rs 138.4 crore from Rs 114.1 crore in Q4 FY25. The company's market capitalization decreased to Rs 21,332 crore following today's trading. Data Patterns shares have gained 45.43% over the past year and 47% since the start of this year, indicating overall strong performance despite the recent setback.
