Mutual Funds

 

Introduction

A mutual fund pools money from many investors and invests it in a professionally managed portfolio of stocks, bonds, cash and/or other assets. Each investor owns units proportional to their investment. Mutual funds make investing accessible and diversified, and are regulated in India by SEBI.

Why investors choose mutual funds

  • Diversification: Reduces company-specific risk by holding many securities.
  • Professional management: Experienced fund managers and research teams.
  • Accessibility: Start with small amounts (SIP from ₹500 in many funds).
  • Liquidity: Open-ended funds can be redeemed (subject to exit loads).
  • Transparency & Regulation: Regular disclosures, NAV published daily.

Major types of mutual funds (with quick use-cases)

  • Equity funds: Invest primarily in stocks. Best for long-term wealth creation (5+ years).
  • Debt funds: Invest in bonds, government securities—lower risk, suitable for income/stability.
  • Hybrid funds: Blend of equity & debt—balance returns and risk.
  • Index funds & ETFs: Track indices like Nifty/Sensex—low-cost, passive investing.
  • Liquid & Ultra Short Duration: Cash-equivalent for treasury management.

How mutual funds work (simplified)

  1. Fund house (AMC) creates the scheme and publishes a prospectus.
  2. Investors subscribe; the AMC pools the money.
  3. AMC’s fund manager invests according to the scheme’s objective.
  4. The fund’s performance is reflected in the Net Asset Value (NAV) per unit.

Key metrics to evaluate a fund

  • NAV: Price per unit.
  • Expense ratio: Annual cost charged by the fund. Lower is generally better for comparable strategies.
  • AUM (Assets under management): Size of the fund.
  • Sharpe ratio / alpha / beta: Risk-adjusted return metrics (useful for mature evaluation).
  • Fund manager track record: Experience and past performance across cycles.

Example: SIP growth (worked calculation)

Suppose you invest ₹10,000 per month into an equity fund via SIP for 10 years, and you assume an average annual return of 12% (compounded monthly). SIP future value formula (monthly compounding):

  • Monthly rate, r = 12% / 12 = 1% = 0.01
  • Number of months, n = 10 x 12 = 120

Future value (FV) of SIP:

FV = P x [ ((1 + r)^n – 1) / r ] x (1 + r)

Where P = monthly SIP


Calculate:

  • (1 + r)^n = 1.01^120 ≈ 3.3000
  • ((1.01^120) – 1) / 0.01 = (3.3000 – 1) / 0.01 = 2.3000 / 0.01 = 230.00
  • FV = 10,000 × 230.00 × 1.01 = 10,000 × 232.30 = ₹23,23,000

So ₹10,000/month for 10 years at ~12% p.a. can become ≈ ₹23.2 lakh.

Note: Past returns do not guarantee future returns. Use conservative assumptions for planning.

Risks & limitations

  • Market risk (especially equity funds)
  • Liquidity & exit load rules in some funds
  • Expense ratio & hidden fees can erode returns
  • Short-term volatility—better to match horizon with fund type

How to choose a mutual fund (practical checklist)

  1. Define your Investment horizon and risk profile.
  2. Compare fund objective vs your goal.
  3. Look at expense ratio and portfolio turnover.
  4. Check consistency of returns across market cycles (3-5 years or more).
  5. Verify SEBI registration and read scheme documents.
