Investor Takeaway

Derivative Pro & Nifty Expert Gulshan Khera, CFP®, believes investors should focus on businesses with strong order books, healthy ROE and ROCE, disciplined capital allocation, consistent EPS growth and sustainable competitive advantages. Among the baskets analysed, AI Infrastructure, Defence Electronics and Shipbuilding currently offer the strongest combination of policy support, earnings visibility and long-term structural demand. However, valuation discipline remains equally important because even excellent businesses can generate poor returns if purchased at excessive valuations.
