Passive investing (index funds/ETFs) aims to match market returns at low cost; active investing tries to beat the market via stock/sector selection. In India, data shows most active funds underperform their benchmarks over time, especially in large caps, making a “passive core + selective active satellite” approach compelling for many investors. (S&P Global)

What we’ll cover
- Clear definitions and India-specific context
- Evidence from SPIVA India on active vs passive outcomes
- Costs, taxes, and regulations that affect net returns
- When to prefer passive, when active may add value
- A practical “Core–Satellite” template with evaluation checklists
- Formulas you can use (CAGR, Sharpe, alpha, tracking error)

Passive vs Active — Indian context
Passive investing
- Buys a basket that replicates an index (e.g., Nifty 50, Sensex) via index funds or ETFs.
- Objective: match the benchmark; performance depends on tracking difference/tracking error and costs.
- ETFs require a demat/trading account; index funds don’t. AMFI defines ETFs as marketable securities that track an index or asset basket. (AMFI India)
Active investing
- A fund manager selects securities hoping to beat the benchmark (generate “alpha”).
- Returns vary widely; results are highly manager- and process-dependent.
Regulatory note (passive): SEBI’s passive-fund framework sets tracking-error/difference standards and disclosures (e.g., equity ETF/index-fund tracking error limits), improving transparency for investors. (Securities and Exchange Board of India, Moneylife)

What the data says (India)
- Year-end 2024: 60% of India large-cap active funds underperformed their benchmark; mid/small-cap underperformance was also material. (S&P Global)
- Passive investing has scaled fast: Index-fund AUM share within passive rose ~6.5x from March 2019 to March 2024, reflecting investor preference for low-cost, rules-based exposure. (AMFI India)
Takeaway: Over multi-year horizons, a majority of active funds lag their benchmarks, especially in efficient, research-heavy large caps. Passive vehicles offer highly competitive, low-drag market exposure. (S&P Global)

Costs and taxes drive your net return
Expense ratios (TER):
- Passive funds typically carry lower TERs than active funds.
- SEBI requires separate disclosure of expenses for direct vs regular plans, helping investors see the real cost gap. Prefer Direct if you don’t need distributor services. (CAalley)
Tax rules (from 23 July 2024):
- Equity (listed equity shares & equity-oriented MFs): LTCG 12.5% above ₹1.25 lakh annual exemption; STCG 20%. (Applies to sales on/after 23-Jul-2024; earlier sales follow old rates.) Consult your CA for specifics. (The Economic Times)

Risk–return mechanics (with simple formulas)
- CAGR: CAGR=(Ending ValueBeginning Value)1/n−1\text{CAGR} = \left(\frac{\text{Ending Value}}{\text{Beginning Value}}\right)^{1/n} – 1
- Sharpe Ratio: Sharpe=Rp−Rfσp\text{Sharpe} = \frac{R_p – R_f}{\sigma_p}
- Jensen’s Alpha (active skill): α=Rp−[Rf+β(Rm−Rf)]\alpha = R_p – [R_f + \beta(R_m – R_f)]
- Tracking Error (passive precision):
TE=Var(Rp−Rb)\text{TE} = \sqrt{\text{Var}(R_p – R_b)} (lower is better for passive)
Funds must disclose tracking error/tracking difference as per SEBI/AMFI. (Securities and Exchange Board of India, AMFI India)

When passive works best in India
- Core large-cap exposure: Markets like Nifty 50/Sensex are hard to beat after costs. (S&P Global)
- Fee sensitivity: Lower TERs compound advantage over long holding periods.
- Rule-based discipline: Removes behavioral errors (fear/greed).
- Transparency & compliance: Standardized disclosures on tracking metrics help you compare options. (Securities and Exchange Board of India)
Where active can still add value
- Less-efficient segments: Mid/small caps or niche themes where bottom-up research, liquidity awareness, and risk control can matter (though SPIVA still shows many underperform). (S&P Global)
- Flexi/Focused mandates: Skilled managers with clear process and risk discipline may deliver alpha, but persistence is rare.
- Tax-aware or downside-aware styles: Active strategies aiming to reduce drawdowns or defer taxes may suit certain investors.

Building a pragmatic portfolio: Core–Satellite
Template (illustrative; not advice):
- 60–80% Passive Core: Nifty 50/Next 50/Total-Market index funds or ETFs.
- 20–40% Active Satellites: 1–3 active strategies (e.g., mid-cap, small-cap, or focused).
- Rebalance annually or at ±5% bands to maintain risk.
Why it works:
- The core locks in market beta at low cost.
- The satellite gives limited, intentional shots at alpha without dominating risk.

How to choose a passive fund (checklist)
- Tracking difference & error: Prefer funds with low, stable TD/TE and consistent index replication methodology (full replication vs sampling). Use AMFI/AMC disclosures. (AMFI India)
- Costs: Compare TER (Direct vs Regular); verify disclosures per SEBI circular. (CAalley)
- Liquidity (for ETFs): Look at average traded value, bid–ask spreads, and market-maker presence.
- Operational hygiene: Corporate action handling, cash drag, and rebalancing discipline (quarterly/periodic index changes).
How to choose an active fund (checklist)
- Rolling-period performance: Evaluate 3Y/5Y rolling excess returns vs benchmark, not point-to-point.
- Risk metrics: Downside capture ratio, volatility, maximum drawdown.
- Process & people: Documented investment framework; team depth; portfolio turnover; size/liquidity fit.
- Costs & taxes: Higher TER needs clear value-add; be mindful of after-tax returns under the new regime. (The Economic Times)

Featured comparison (for quick scanning)
| Feature | Passive (Index Funds/ETFs) | Active Funds |
| Objective | Match benchmark | Beat benchmark |
| Cost (TER) | Generally low | Higher |
| Skill dependency | Low | High (manager-driven) |
| Outcome dispersion | Tight around index (TD/TE matter) | Wide (win/lose risk) |
| Suitable for | Core allocation, long-term SIPs | Satellite, niche/alpha attempts |
| Evidence in India | Majority of active funds underperform over time | A minority outperform consistently |

Worked example (back-of-the-envelope)
- Invest ₹10 lakh for 10 years; market (index) CAGR 12%.
- Passive TER 0.2% vs Active TER 1.8% (illustrative).
- Passive expected CAGR ≈ 11.8%; Active must add ≥1.6% alpha just to break even after fees—before taxes and mistakes.
- Over 10 years, a 1.6% annual gap can mean ₹3–4 lakh difference in terminal wealth.

FAQs
Q1) ETF or index fund for SIP?
If you don’t want a demat/trading account or care about bid–ask spreads, an index fund is simpler. ETFs may be marginally cheaper but require trading discipline and liquidity checks. (AMFI India)
Q2) What’s “tracking difference” vs “tracking error”?
- Tracking difference: Average return gap vs index (often driven by TER & cash drag).
- Tracking error: Volatility of that gap (day-to-day dispersion). SEBI mandates disclosures and caps for certain passive categories. (Securities and Exchange Board of India, Moneylife)
Q3) How do taxes now affect my choice?
Since 23-Jul-2024, equity LTCG is 12.5% above ₹1.25 lakh exemption and STCG is 20%; higher churn in some active funds can elevate realized gains. Align product choice with your horizon and tax bracket. (The Economic Times)
Q4) Is passive always better?
Not always. In less efficient pockets (certain small/micro-caps, special situations), skilled active managers may add value. Keep such bets as satellites, sized prudently. (S&P Global)

Key takeaways
- In India, passive works well as a low-cost core, especially for large-cap exposure; the data backs it. (S&P Global)
- Active is optional alpha—use it surgically where odds and manager skill justify costs. (S&P Global)
- Taxes and fees materially shape your net outcomes; prefer Direct plans where appropriate and mind the post-2024 tax rules. (CAalley, The Economic Times)
- A Core–Satellite design balances efficiency with opportunity and is easy to manage via SIPs and periodic rebalancing.
