By Meghna Sharma When investors build a portfolio, one of the most important decisions is whether to follow an active or passive investment strategy. Active portfolio management involves selecting securities and changing portfolio allocations with the aim of outperforming a benchmark. Passive management, in contrast, seeks to replicate the performance of a particular market index rather than consistently beat it.
Neither approach is guaranteed to produce better returns. However, differences in cost, diversification, flexibility, risk and the ability to outperform can make one approach more suitable than the other for different investors. In India, the debate has become increasingly relevant as index funds and ETFs have grown alongside traditional actively managed mutual funds.
What Is Active Portfolio Management?
In an active portfolio, a fund manager uses research, market analysis and investment judgment to decide which securities to buy, hold or sell.
The objective is generally to generate alpha, or returns above an appropriate benchmark after considering the relevant investment framework.
Active managers may:
- Select individual stocks
- Change sector allocations
- Increase or reduce cash exposure where permitted
- Avoid companies they consider overvalued
- Increase exposure to companies they consider attractive
- Adjust portfolios as market conditions change
For example, an active Indian equity fund may invest differently from the Nifty 50 because the fund manager believes certain companies have stronger earnings potential than their index weight suggests.
The potential advantage is flexibility. The disadvantage is that the strategy depends heavily on investment decisions and involves higher management costs than a straightforward index-tracking approach in many cases.
What Is Passive Portfolio Management?
Passive portfolio management aims to replicate the performance of a specified index or benchmark.
An index fund, for example, may attempt to hold the securities of the Nifty 50 in proportions that closely resemble the index. ETFs can follow a similar approach.
SEBI describes index mutual funds as schemes that aim to replicate the performance of an index rather than attempting to outperform it. Because they generally require less active research and trading, their management costs can be lower.
The objective of passive investing is therefore not to identify the next outperforming stock. Instead, it is to obtain broad market exposure at relatively low cost while keeping the difference from the benchmark—known as tracking error—under control.
Active vs Passive: Cost Difference
Cost is one of the strongest arguments for passive investing.
An actively managed fund generally requires research teams, portfolio managers, analysts and more investment decision-making. These activities can contribute to higher expenses.
Passive funds generally have simpler portfolio-management requirements. AMFI notes that passive funds typically have lower expense ratios than active funds.
The difference in costs can become significant over long investment periods because expenses reduce the amount of money that remains invested.
For example, suppose two portfolios earn the same gross return before expenses. If one has materially higher annual costs, its investor will receive a lower net return over time.
SEBI explains that the expense ratio represents a scheme’s annual operating expenses as a percentage of its assets, and these expenses affect the fund’s NAV.
Can Active Funds Beat Passive Funds?
Yes. Active funds can and do outperform their benchmarks in individual periods.
The problem is consistency.
S&P Dow Jones Indices’ SPIVA India Year-End 2025 report found that 75% of Indian large-cap active funds underperformed the S&P India LargeMidCap index in 2025. Over the 3-, 5- and 10-year periods ending December 2025, the corresponding underperformance rates were 74.2%, 84.4% and 76.3%.
The results were not identical across categories. Indian mid- and small-cap active funds had a much better 2025, with only 12.1% underperforming their benchmark during the year. However, over 10 years, 79.0% underperformed.
This demonstrates an important point: active management can outperform, but identifying managers who will consistently outperform in advance is difficult.
Why Passive Investing Has an Advantage
Passive investing starts with a relatively simple objective: match the market rather than beat it.
Its major advantages include:
Lower Costs
Lower management expenses can leave more of the portfolio’s gross return with investors.
Diversification
A broad index can provide exposure to numerous companies and sectors through a single investment.
Transparency
Investors generally know which benchmark the fund is designed to track.
Less Manager Dependence
The investment outcome is less dependent on an individual fund manager’s stock-selection decisions.
Consistency
The objective remains relatively stable: track the selected index rather than continuously change the investment thesis.
However, passive investing is not risk-free. A passive fund will generally participate in market declines because it is designed to track the market.
Why Active Investing Still Has a Role
If passive investing has cost and consistency advantages, why would investors choose active management?
One reason is that markets are not perfectly efficient in every segment.
An active manager may identify companies whose valuations do not accurately reflect their future earnings potential. In less-followed segments, specialised sectors or smaller companies, professional research may potentially uncover opportunities that an index strategy cannot deliberately select.
Active managers can also construct portfolios differently from the benchmark.
For example, if a manager believes a particular sector is overvalued, the fund may reduce exposure to it, subject to the scheme’s mandate. A passive fund generally cannot make that decision because its primary objective is to follow the index.
Active vs Passive: Key Comparison
| Factor | Active Management | Passive Management |
| Main objective | Beat benchmark | Track benchmark |
| Stock selection | Fund manager driven | Index driven |
| Management style | Flexible | Rules-based |
| Costs | Generally higher | Generally lower |
| Diversification | Depends on portfolio | Usually broad in broad-market funds |
| Manager dependence | High | Relatively low |
| Tracking error | Not the primary objective | Important consideration |
| Outperformance potential | Possible | Not the objective |
| Risk of underperforming benchmark | Meaningful | Usually limited to tracking difference |
| Suitable for | Investors seeking active decisions | Investors seeking low-cost market exposure |
What About Market Conditions?
The relative performance of active and passive strategies can change with market conditions.
Active managers may have greater opportunities when there is significant dispersion between individual stocks or sectors. If some companies perform substantially differently from others, stock selection can potentially add value.
On the other hand, when a small number of large companies drive index performance, active managers who hold different positions may struggle to keep up.
This means there is no permanent market environment in which active management must always win.
Tax and Portfolio Turnover Considerations
Portfolio turnover can also differ.
Active managers may trade more frequently as they adjust their holdings. Higher trading activity can create transaction-related costs and may affect tax efficiency depending on the investment structure and investor’s circumstances.
Passive funds generally have lower turnover because they primarily change holdings when the underlying index changes or when portfolio adjustments are required.
However, turnover varies between individual funds, so investors should examine the actual scheme rather than assume that every active fund trades heavily or every passive fund trades minimally.
Which Is Better for Long-Term Investors?
For many investors seeking a simple, diversified, low-cost core portfolio, passive investing can be attractive.
A broad-market index fund can provide market exposure without requiring the investor to identify a fund manager capable of consistently outperforming the benchmark.
Active funds may be more appropriate for investors who understand the additional costs and are willing to accept manager-selection risk in exchange for the possibility of outperforming the benchmark.
The distinction is particularly important in India because the historical evidence differs significantly across fund categories. The fact that many large-cap active funds have struggled against benchmarks does not mean every active category or every active manager will perform poorly.
A Combination Can Also Work
Investors do not necessarily have to choose exclusively between active and passive management.
A portfolio could use passive funds for its core allocation and selectively use active funds for particular categories where the investor believes skilled management may add value.
For example, an investor might use a broad-market index fund for core large-cap exposure while allocating a smaller portion to an actively managed strategy in a segment where they are comfortable accepting additional manager risk.
This approach can provide a balance between cost efficiency and the potential benefits of active decision-making.
How Should Investors Decide?
Before selecting active or passive management, consider:
- Investment objective: Are you trying to match the market or outperform it?
- Time horizon: Longer periods make the effect of costs increasingly important.
- Risk tolerance: Active funds can deviate substantially from their benchmarks.
- Costs: Compare expense ratios and other relevant costs.
- Fund-manager track record: For active funds, examine performance across multiple market cycles.
- Benchmark: Always compare a fund with an appropriate benchmark.
- Tracking error: For passive funds, examine how closely the fund has followed its index.
- Portfolio diversification: Understand what securities and sectors you actually own.
So, Which One Wins?
There is no universal winner.
Passive management generally wins on simplicity, cost and consistency of market exposure. Active management wins only when the manager can generate sufficient additional value to overcome the costs and successfully outperform the relevant benchmark over a meaningful period.
The latest Indian SPIVA evidence provides an important lesson: active management can succeed in some categories and periods, but persistent outperformance is difficult. In the decade ending December 2025, a majority of active funds in every category covered by the SPIVA India Scorecard underperformed their respective benchmarks.
Therefore, investors should not choose active funds simply because they expect a professional manager to beat the market, nor should they assume that every passive fund is automatically superior.
Conclusion
Passive vs active portfolio management is ultimately a choice between attempting to beat the market and attempting to efficiently capture the market’s return.
Active management provides flexibility, professional security selection and the possibility of generating alpha, but investors pay for that opportunity and face the risk that the manager will underperform.
Passive management offers lower costs, broad diversification and a rules-based approach, but it cannot deliberately avoid an index’s decline or select individual stocks for superior returns.
For many long-term investors, a low-cost passive strategy can serve as a strong portfolio foundation, while carefully selected active strategies may complement it where there is a clear investment rationale.
The real winner is therefore not necessarily active or passive. The better approach is the one that matches the investor’s goals, risk tolerance, costs and ability to remain invested over the long term.
