Advanced Mutual Funds
So you know what a Mutual Fund is. You have a SIP. But how do you know if your fund is actually good? Star ratings (5-star) are often misleading. Let's look at the real metrics.
1. Rolling Returns (The Truth Teller)
Most people look at "Point-to-Point" returns.
- "Fund A gave 15% in last 3 years."
- This is biased by the start and end date.
Rolling Returns calculates returns for every possible 3-year period in history.
- It tells you: "If I invested on ANY day, what is the probability of making money?"
- Good Fund: Consistent Rolling Returns (e.g., always > 10%).
- Bad Fund: Volatile Rolling Returns (sometimes 50%, sometimes -20%).
2. Risk Ratios (The Report Card)
Alpha (α) - The Outperformance
- Measures how much extra return the fund manager generated over the benchmark.
- Example: Benchmark (Nifty) gave 10%. Fund gave 12%. Alpha = +2%.
- Rule: Higher Alpha is better. Negative Alpha means manager failed.
Beta (β) - The Volatility
- Measures how much the fund moves compared to market.
- Beta = 1: Moves exactly like market.
- Beta > 1: More volatile (High Risk).
- Beta less than 1: Less volatile (Stable).
- Rule: For conservative investors, Beta less than 1 is good.
Sharpe Ratio - Return per Unit of Risk
- Formula: (Fund Return - Risk Free Rate) / Standard Deviation.
- Meaning: "Is the risk worth it?"
- Rule: Higher Sharpe Ratio is better. It means you are getting more return for the same risk.
3. Portfolio Overlap
If you own 4 funds, check their overlap.
- Fund A owns HDFC Bank, Reliance, Infosys.
- Fund B owns HDFC Bank, Reliance, Infosys.
- Result: You are paying two expense ratios for the same stocks!
- Tool: Use "Fund Overlap" tools online. Keep overlap less than 30%.
4. Expense Ratio Impact
A 1% difference sounds small, but over 20 years, it's massive.
Scenario: ₹10 Lakh investment for 20 years @ 12% return.
- Direct Plan (1% Expense): Corpus = ₹86 Lakhs.
- Regular Plan (2% Expense): Corpus = ₹72 Lakhs.
- Loss: ₹14 Lakhs! Just because of 1% fee.
5. Active Share
Measures how different the fund is from the Benchmark.
- Active Share = 0%: It's an Index Fund (Copycat).
- Active Share > 60%: True Active Management.
- Trap: "Closet Indexing" - Charging high fees but just copying the index. Avoid funds with low Active Share and high fees.
7-Day Action Plan
Day 1: Go to ValueResearch or Morningstar. Search your fund.
Day 2: Check Alpha. Is it positive over 3 and 5 years?
Day 3: Check Beta. Is it aligned with your risk profile?
Day 4: Check Rolling Returns graph. Is it consistent?
Day 5: Check Expense Ratio. Is it lower than category average?
Day 6: Use a "Portfolio Overlap" tool to check your funds.
Day 7: If a fund has consistently negative Alpha and high Expense Ratio, stop the SIP and switch.

1. What does a positive Alpha indicate?
💡 Final Wisdom: Don't marry your mutual fund. Review it every year. If the manager changes or performance drops (Alpha becomes negative), divorce it.
