Drone and defense stocks in India have surged since Operation Sindoor began, following the Pahalgam terrorist attack. Key companies like Bharat Electronics and Hindustan Aeronautics have seen stock increases of 8-50%. Analysts attribute this growth to strong order expectations, despite a cautious outlook due to economic uncertainty. India's defense sector is evolving, highlighted by the integration of advanced technologies and a focus on swift retaliation against terrorism. Experts believe that while defense stocks are reasonably valued, future growth will depend on various factors.
