Sector Analysis in India: Complete Guide to Investing by Sector

Amit’s Sector Strategy

Amit invested ₹10 lakh in 2015—all in PSU bank stocks. “Banking is the backbone of economy,” he reasoned.

By 2020, his portfolio was down 60%.

Meanwhile, his colleague Smita invested in IT and pharma stocks. Her portfolio was up 200%.

Same market, same time, very different results.

The difference? Sector selection.

This guide will teach you how different sectors behave and when to invest in each.

Why Sector Analysis Matters

Different Sectors, Different Behavior

The Sector Rotation Principle

Different sectors perform best at different stages of economic cycle:

Early Recovery → Financials, Consumer Discretionary
Mid Expansion → Industrials, Technology

Mistake 3: All Eggs in One Sector

Problem: 100% in banking because “it’s safe” Reality: Even “safe” sectors can underperform for years

Mistake 4: Not Understanding the Business

Problem: Buying pharma without understanding FDA regulations Reality: Sector-specific risks can hurt badly
