Harshit Kapadia of Elara Securities prefers Hindustan Aeronautics, Bharat Electronics (PSU) and Data Patterns, Astra Microwave, Zen Technologies (private). Modi’s Russia visit for defense ties boosts small arms and air defense. Hindustan Aeronautics tops Kapadia’s list. Indigenization, order books, manufacturing, shipbuilding timelines (6-11 years), and fighter aircraft offer valuation gaps for PSU stocks.
