How Mutual Funds React in Bull Markets

Introduction

When stock markets rally and investor optimism runs high, we officially enter a bull market. But not all mutual funds behave the same way during these phases. Some sprint ahead, some trot steadily, and others lag behind.

This blog explores how mutual funds of different types react during bull runs and how investors can benefit (or falter) based on their fund choices — illustrated through the story of Ankit and Nisha.

Understanding Bull Markets

A bull market is defined as a sustained rise of 20% or more in market indices from recent lows. It’s usually driven by economic growth, rising corporate earnings, and positive investor sentiment.

Key characteristics:

  • Strong equity performance
  • Sectoral outperformance (Tech, Midcaps, Smallcaps)
  • Increased SIP inflows and lump-sum investments
  • Investor overconfidence and FOMO (Fear of Missing Out)

How Different Funds React

  • Large Cap Funds: Rise steadily. Blue-chip companies participate in growth but with lower volatility.
  • Mid & Small Cap Funds: Often outperform due to faster earnings growth and increased investor appetite.
  • Sectoral/Thematic Funds: Can shoot up quickly if the theme aligns with the bull run (e.g., Tech in 2021).
  • Balanced Advantage Funds (BAFs): Participate partially as they rebalance based on valuations.

Real-Life Example: Ankit vs. Nisha

  • Ankit invested in a Tech Sector Fund in 2020. By 2021, he saw a 40% return as IT stocks surged. But in 2022, tech corrected sharply, and Ankit exited at a loss, erasing gains.
  • Nisha stayed consistent with her Large & Flexi Cap Fund SIPs throughout. She saw steady 15% CAGR during the same period and stayed invested, avoiding panic.

    Key Takeaways

Fund Types Table
Fund Type Bull Market Behavior Investor Tip
Large Cap Moderate, steady growth Good for stability
Mid & Small Cap High returns, high volatility Use SIPs to average costs
Sectoral/Thematic Can skyrocket, but risky Suitable only with high-risk appetite
Balanced Advantage Partial participation, smoother ride Good for conservative investors

Conclusion

Bull markets offer opportunities, but they also test investor discipline. Avoid chasing returns blindly. Match your fund with your risk profile and time horizon to ride the bull safely.


Don’t get swept away by market highs. Review your fund types, stay diversified, and stick to your plan. Bull markets reward the patient and the prepared.
