What each structure is
Three structures, three starting assumptions
What a SIF is
A Specialised Investment Fund is a distinct category within the mutual fund regulatory framework. Investors are pooled into an investment strategy, units are held against a Net Asset Value, and the strategy is permitted a wider toolkit than a conventional mutual fund scheme — including limited unhedged short exposure through exchange-traded derivatives, within prescribed limits.
A general minimum investment of ₹10 lakh applies in aggregate at PAN level across the investment strategies of one SIF, with an exemption available to accredited investors. Because a SIF sits inside the mutual fund framework, it carries mutual-fund-style disclosure, valuation and reporting discipline.
What a PMS is
A Portfolio Management Service does not pool money. Securities are held in the investor’s own name, in the investor’s own demat account, and the portfolio manager manages that account individually. The minimum investment for a discretionary PMS relationship is ₹50 lakh.
Because the portfolio is client-specific rather than pooled, holdings are visible at the security level and can, in principle, be adapted to the individual investor. That visibility is real. It is not the same thing as a better outcome.
What an AIF is
An Alternative Investment Fund is a privately pooled vehicle registered under a separate SEBI framework, organised across three categories with different permitted mandates. The standard minimum investment is ₹1 crore per investor, with narrow specified exceptions.
An AIF may access exposures a mutual fund structure cannot readily hold — including unlisted, private, credit-oriented or long-short mandates depending on category. Many AIF strategies are also close-ended or subject to defined tenures, which changes how and when money can be withdrawn.
Compare the structure first
SIF vs PMS vs AIF: compare the structure before the return
Comparing the three on past returns is the most common mistake, because the three structures do not run the same mandates, do not carry the same liquidity terms and are not reported on the same basis. Comparing them on structure is far more useful.
| Dimension | SIF | PMS | AIF |
|---|---|---|---|
| Regulatory home | A distinct category within the mutual fund framework. | The SEBI portfolio managers framework. | A separate SEBI framework, organised into three categories. |
| How the portfolio is held | Pooled. The investor holds units valued at NAV. | Client-specific. Securities are held in the investor’s own name and demat account. | Pooled. The investor holds units or interests in the fund. |
| General minimum investment | ₹10 lakh in aggregate at PAN level across the strategies of one SIF, with an accredited-investor exemption. | ₹50 lakh for a discretionary relationship. | ₹1 crore per investor, with narrow specified exceptions. |
| Typical mandate flexibility | Wider than a conventional scheme, including limited unhedged short exposure within prescribed limits. | Depends on the specific PMS strategy; generally listed-market portfolios. | Widest, and category-dependent — may include unlisted, private or credit exposures. |
| Portfolio visibility | Strategy-level disclosure on a mutual-fund basis. | Security-level, in the investor’s own account. | Fund-level reporting, on terms set in the fund documents. |
| Liquidity pattern | Defined by the strategy — subscription and redemption terms, notice periods and NAV timing vary by strategy. | Generally open, but exiting means selling underlying securities, which has market and tax consequences. | Frequently the most restricted — many mandates are close-ended or tenure-bound. |
None of these differences tells you whether the strategy will perform, whether the risk is one you can hold, or whether the exposure belongs in your portfolio at all. They tell you what you would be signing up to.
The concentration lens
The minimum ticket tells you how concentrated the decision becomes
The single most under-examined consequence of a higher minimum is concentration. A minimum investment is not a quality signal — it is a constraint that forces a fixed amount of money into one decision, regardless of how large the portfolio is.
The same absolute ticket has a very different meaning at different portfolio sizes.
| Illustrative total portfolio | SIF at ₹10 lakh | PMS at ₹50 lakh | AIF at ₹1 crore |
|---|---|---|---|
| ₹50 lakh | 20% of the portfolio in one strategy. | 100% of the portfolio in one mandate. | Not available at this portfolio size. |
| ₹1 crore | 10% of the portfolio in one strategy. | 50% of the portfolio in one mandate. | 100% of the portfolio in one fund. |
| ₹2 crore | 5% of the portfolio in one strategy. | 25% of the portfolio in one mandate. | 50% of the portfolio in one fund. |
These are arithmetic illustrations of the minimum ticket, not recommendations, targets or suggested allocations. They exist to make one point visible: the higher the minimum, the larger the share of the portfolio that a single decision must carry, and the stronger the reason for that decision has to be.
Does a PMS offer more personalisation than a SIF or an AIF?
A PMS is genuinely more individual, because the securities are held in the investor’s own name and the account is managed separately. That is a real structural difference from a pooled SIF or AIF.
Individual is not the same as personalised. Many PMS strategies run a substantially similar model portfolio across clients, with differences arising largely from entry timing rather than from a portfolio designed around one investor’s goals, existing exposures, liquidity needs and behaviour.
Genuine personalisation lives in the plan — what the money is for, when it is needed, how much risk the household can actually hold, and what the investor will do when the strategy underperforms. That work sits above the product, and no structure supplies it automatically.
The burden of proof
What does a more complex structure have to prove?
Complexity carries a burden of proof. Before a SIF, a PMS or an AIF earns a place, it should be able to answer four things clearly:
- The job. What specific role will this perform that the current portfolio cannot?
- The alternative. Could a simpler, cheaper, more liquid structure do the same job adequately?
- The cost of being wrong. If the strategy disappoints, how much of the portfolio is affected, and how long is the money committed?
- The understanding. Can the investor explain the mandate, the risk and the exit terms without relying on the pitch?
If any of the four is unclear, the structure has not yet earned the allocation — regardless of who is managing it.
What can the portfolio actually own or do?
Mandate breadth is where the three structures diverge most meaningfully. A SIF operates with a wider toolkit than a conventional mutual fund scheme but remains inside the mutual fund framework and its disclosure discipline. A PMS typically constructs listed-market portfolios within the terms of the specific strategy. An AIF has the widest scope and, depending on category, may hold exposures that neither of the others can readily access.
Breadth is only an advantage when the portfolio needs it. Additional flexibility that is not required simply adds risk, cost and monitoring effort. Ask what the mandate permits, then ask whether the portfolio has any use for what it permits.
How should you compare costs across SIF, PMS and AIF?
Headline fees rarely tell the whole story. A structural comparison should look at every layer that reduces the investor’s outcome:
- Ongoing management fees, and how they are charged and disclosed.
- Performance-linked fees, including the hurdle, the catch-up and whether a high-water mark applies.
- Transaction, custody, administration and operating expenses.
- Exit loads, redemption terms and any early-exit penalties.
- The tax consequences of how the structure realises gains.
Two structures quoting a similar management fee can deliver materially different net outcomes once performance fees, portfolio turnover and tax treatment are included. Compare after-cost, after-tax outcomes on comparable mandates — not fee lines in isolation.
Should past performance decide between a SIF, a PMS and an AIF?
No — and cross-structure performance comparison is particularly unreliable. Track records differ in mandate, period, liquidity terms, cash treatment, fee basis and reporting convention. A number that is not comparable cannot support a decision, however precise it appears.
Performance evidence becomes useful only after the portfolio role is defined and a genuinely comparable peer group has been established. Sequence matters: role first, comparability second, evidence third.
Which is more liquid: a SIF, a PMS or an AIF?
Liquidity is usually the difference investors underestimate most.
A SIF’s liquidity is defined by the individual strategy — subscription and redemption windows, notice periods and applicable NAV timing all vary by strategy and must be read in the strategy documents. A PMS is generally open-ended in form, but exiting requires selling the underlying securities, which carries market impact and tax consequences. Many AIF mandates are the most restricted of the three, with close-ended structures, defined tenures and limited or no interim exit.
Liquidity should be matched to the goal, not to optimism. Money that may be needed within a defined horizon should not sit in a structure whose exit terms are uncertain.
Are SIF, PMS and AIF taxed differently?
Yes. Taxation follows the structure and, within each structure, the nature of the underlying portfolio — so a single blanket comparison is not possible.
In broad terms: a SIF is taxed on mutual-fund principles, where the classification of the underlying strategy determines treatment. A PMS is taxed in the investor’s own hands on the underlying securities, because the investor directly owns them, which makes portfolio turnover directly relevant. An AIF’s treatment depends on its category and the applicable pass-through rules.
Tax outcomes should be confirmed for the specific strategy and the investor’s own circumstances before committing. For the mutual fund and SIF side of this question, read FinEdge’s guide to SIF rules, taxation, liquidity and costs.
The FinEdge decision test
How should you choose between a SIF, a PMS and an AIF?
Work through the decision in this order. If the first question has no clear answer, the remaining six are premature.
- What specific job would this investment perform in the portfolio?
- Does the current portfolio already do that job, adequately, at lower cost?
- What proportion of the portfolio would the minimum ticket commit to one decision?
- How long is the money committed, and on what exit terms?
- What is the full cost stack, including performance fees and tax?
- Can the mandate, the risk and the exit terms be explained in plain language?
- What will be done if the strategy underperforms for an extended period?
A mutual fund can still be the right answer
For most investors — including many with large portfolios — a well-constructed mutual fund portfolio continues to do the essential work: diversification, asset allocation, goal alignment, cost efficiency, liquidity and behavioural durability.
A SIF, a PMS or an AIF becomes worth examining only when a defined portfolio job cannot be performed by that simpler structure, and the investor can carry the additional concentration, cost, complexity and illiquidity that comes with the alternative.
If you are still comparing the SIF structure with what you already own, start with SIF vs Mutual Fund: what is the difference, and then read the different types of SIFs in India.
The closing principle
The best structure is the one the portfolio can justify
SIF, PMS and AIF are not a hierarchy of sophistication. They are three different answers to three different structural problems, each with its own access rule, mandate scope, cost pattern and liquidity discipline.
The right question is never which one is the most advanced. It is whether a clearly defined portfolio job exists, whether a simpler structure can already perform it, and whether the investor can hold the chosen structure through the periods when it disappoints.
