What Is a Mutual Fund?
NAV, units, AMCs, direct vs regular — understand the structure before you invest a rupee.
The Core Concept
A mutual fund pools money from thousands of investors and invests it in stocks, bonds, or other securities. You get professional management, diversification, and liquidity — without needing ₹10 crore to build your own portfolio.
- AMC: the entity that manages the fund. HDFC AMC, SBI AMC, Mirae Asset, Axis, etc.
- Fund Manager: the professional who decides what to buy and sell inside the fund.
- SEBI oversight: all mutual funds in India are regulated by SEBI.
NAV — Net Asset Value
- NAV = (Total Assets − Liabilities) ÷ Total Units Outstanding
- NAV is the per-unit price, calculated at end of every business day.
- A fund at NAV ₹50 is NOT cheaper than one at ₹500 — NAV alone means nothing.
Direct vs Regular Plans
- Regular plan: bought through a distributor. Higher expense ratio.
- Direct plan: bought from AMC or platforms like Kuvera, Zerodha Coin. Lower expense ratio.
- Difference: 0.5–1.5%/year. On ₹10L over 20 years — regular plan costs ₹18–35L extra in fees.
- Always buy direct plans.
Growth vs IDCW Option
- Growth: profits stay inside the fund, NAV grows. Best for wealth creation.
- IDCW: fund periodically pays out money by reducing NAV. Taxable as income.
- Always choose Growth option for long-term investing.
Types of Mutual Funds
Equity, debt, hybrid, index — know which fund does what and when to use each type.
Equity Funds
Invest primarily in stocks. Best for long-term goals (5+ years).
- Large-cap: top 100 stocks. Lower volatility. For conservative equity investors.
- Mid-cap: stocks ranked 101–250. Higher potential, higher risk. 7+ year horizon.
- Small-cap: ranked 251+. Highest risk/return. Only for 10+ year horizon.
- Flexi-cap: fund manager can invest across all sizes. Good default equity choice.
- ELSS: 3-year lock-in, qualifies for 80C deduction. Best tax-saving instrument.
Debt Funds
Invest in bonds and money market instruments. For short/medium-term goals.
- Liquid funds: <91 day maturity. Safer than savings account for 1–6 month parking.
- Short duration: 1–3 year horizon.
- Post April 2023: debt fund gains taxed at slab rate regardless of holding period.
Index Funds and ETFs
- Index fund: passively tracks an index (Nifty50). Low expense ratio (0.1–0.3%).
- Most active funds fail to beat Nifty50 consistently over 10 years. Index funds win here.
Goal-Based Selection
- Goal <1 year → Liquid fund
- Goal 1–3 years → Short duration / corporate bond
- Goal 3–5 years → Balanced advantage fund
- Goal 5+ years → Equity / index fund
How to Choose the Right Fund
Expense ratio, rolling returns, alpha — a systematic framework to pick funds that actually perform.
Don't Use 1-Year Returns
1-year returns are the most misleading number in MF marketing. Use rolling returns instead — how the fund performed over every 3-year period, not just one fixed period ending today.
- A good fund should have positive rolling returns in 90%+ of all 3-year windows.
- Available on Valueresearchonline.com and Primeinvestor.in.
Expense Ratio
- Index funds: below 0.3% is good. Above 0.5% for an index fund = switch.
- Active large-cap direct plan: below 1.2% is acceptable.
Alpha — The Real Test
- Alpha = fund return − benchmark return. Positive alpha = beat the index.
- Consistent alpha of 2–3% over 5–7 years = genuine skill.
- Most large-cap active funds deliver zero or negative alpha after expenses.
AUM Size and Manager Tenure
- <₹100 crore AUM: liquidity risk, fund may be wound up. Avoid.
- If the manager who built the 10-year track record left 2 years ago, those returns are irrelevant.
SIP vs Lump Sum
Rupee cost averaging, step-up SIP, XIRR — master the mechanics of systematic investing.
What Is a SIP?
- Invest a fixed amount (e.g., ₹5,000) in a fund on a fixed date every month.
- Auto-debited from your bank. Minimum SIP: ₹100/month on most platforms.
- You can pause, stop, or modify a SIP anytime. Stopping a SIP does NOT redeem your existing units.
Rupee Cost Averaging
- In a falling market: fixed ₹5,000 buys more units. Average cost per unit falls.
- In a rising market: fewer units, but existing units are worth more.
- SIP does NOT guarantee profit — in a prolonged bear market, SIPs can still be negative for years.
Step-Up SIP
- Increase SIP amount by 10% every year to match salary growth.
- ₹5,000/month increasing 10%/year at 12% return = ~₹2.2 crore in 20 years vs ₹1.5 crore flat SIP.
XIRR — The Right Way to Measure SIP Returns
- XIRR is the annualised return on a series of cash flows at different dates.
- "50% absolute return" over 4 years via SIP might only be ~11% XIRR — always use XIRR.
Building Your Mutual Fund Portfolio
3-fund portfolio, asset allocation, rebalancing, tax rules — put it all together.
The 3-Fund Portfolio
- Fund 1 — Nifty50 Index Fund (50%): large-cap India equity core.
- Fund 2 — Nifty Next 50 Index Fund (30%): next tier of India's growth stories.
- Fund 3 — Short Duration Debt Fund (20%): stability + liquidity for short-term goals.
- Total: 80% equity, 20% debt. Adjust ratios based on age and risk tolerance.
Asset Allocation by Age
- Rule of thumb: 110 minus your age = % in equity. At 30 → 80% equity; at 50 → 60% equity.
Annual Rebalancing
- Once a year, check if equity/debt split has drifted from your target.
- If equity has grown from 70% to 80%, sell some equity and move to debt.
- Rebalancing forces you to sell high and buy low automatically.
Tax on Mutual Funds (FY 2024–25)
- Equity LTCG (held >1 year): 12.5% on gains above ₹1.25L/year.
- Equity STCG (held <1 year): 20% flat.
- Harvest ₹1.25L of LTCG every March — sell and rebuy to step up cost basis tax-free.
