Key growth drivers include Make in India initiative driving indigenous manufacturing, defence modernization and equipment upgradation, export opportunities and international partnerships, and growing private sector participation and investment.

Use multiple valuation methods: P/E ratios (15-30x range), P/B ratios (2-5x range), EV/EBITDA (8-20x range), and DCF analysis considering growth prospects. Consider order book, government contracts, and competitive advantages. Focus on companies with strong fundamentals and growth prospects.
