NISM-Series-XXI-A: Portfolio Management Services (PMS) Distributors · Role of Portfolio Managers

Introduction to Portfolio Management Services (PMS) for NISM

Updated 11 October 2026 · Fact-checked

Portfolio Management Services (PMS) is a SEBI-regulated service where a registered portfolio manager manages a client's own portfolio of securities or funds under a contract. Each client holds securities in their own name. To solve questions, identify who decides trades: manager alone is discretionary, client approves each trade is non-discretionary, client only gets advice is advisory.

Understand Introduction to Portfolio Management Services

A portfolio manager is a registered person who, under a contract with a client, advises on, directs, or manages the client's portfolio of securities or funds. The service is called Portfolio Management Services (PMS). It is regulated by SEBI under the SEBI (Portfolio Managers) Regulations, 2020.

The key idea is a separate portfolio for each client. The securities are held in the client's own name, usually with a custodian. They are not pooled into one common fund. So two PMS clients of the same manager can hold different stocks, at different prices, with different returns.

Compare this with a mutual fund. A mutual fund pools money from many investors into one scheme and issues units. All unit holders share the same portfolio and the same NAV. In PMS you own the underlying securities directly. This is why PMS can be customised, and why the investor is taxed on the transactions in their own portfolio. PMS also has a minimum investment of ₹50 lakh per client, which is far higher than a typical mutual fund entry amount.

PMS comes in three types. In discretionary PMS, the manager takes investment decisions on their own, using sole and absolute discretion, as agreed in the contract. In non-discretionary PMS, the manager acts only on the client's express prior instructions, so each transaction needs client consent. In advisory PMS, the manager only gives investment advice. The client decides and executes, and the manager does not carry out the trades.

As a PMS distributor, you bring clients to portfolio managers. So you must know what the product is, who it suits, and how it differs from other products. The exam is 100 MCQs with 10% negative marking, so clear definitions protect your score.

How to solve Introduction to Portfolio Management Services questions

Use this method for any question on what PMS is, how it differs from other products, or which type applies.

  1. 1Read the question and mark the key clue: who takes the investment decision, who executes, or whether the money is pooled.
  2. 2If the question is about the product, check pooling. Pooled with units and one NAV means a mutual fund. Individual portfolio in the client's name means PMS.
  3. 3If the question is about the type, ask who decides. Manager alone means discretionary. Manager acts only after client instruction means non-discretionary. Client decides and executes after advice means advisory.
  4. 4Check for numbers. The minimum PMS investment is ₹50 lakh per client.
  5. 5Cross out options that mix features, such as a pooled portfolio with individual ownership.
  6. 6Pick the option that matches the exact definition, not the one that sounds most general.
  7. 7If two options remain, choose the one that matches the regulation wording.

Quickest way: Three-question filter

When to use it: When you have under a minute per question and the question compares products or PMS types.

  1. Pooled or individual? Pooled means mutual fund, individual means PMS.
  2. Who decides the trade? Manager means discretionary, client approval means non-discretionary, client alone means advisory.
  3. Who executes? In advisory PMS the client does. In the other two types the manager does.
  4. Pick the option that fits all three answers.

Common mistakes in Introduction to Portfolio Management Services

  • Saying PMS pools client money into one fund with a common NAV.

    You mix up PMS with mutual funds because both involve a professional manager.

    Fix: Remember: mutual funds pool and issue units. PMS keeps a separate portfolio for each client, held in the client's name.

  • Treating non-discretionary PMS as one where the manager decides freely.

    The word 'portfolio manager' suggests the manager always decides.

    Fix: Only discretionary PMS gives the manager sole discretion. In non-discretionary PMS, each transaction needs the client's prior instruction.

  • Believing the manager executes trades in advisory PMS.

    You assume all PMS types involve trading by the manager.

    Fix: In advisory PMS the manager only advises. The client takes the decision and executes.

  • Mixing up the ₹50 lakh minimum with a mutual fund's small minimum.

    Both are investment products and you blur the entry limits.

    Fix: Link PMS with a high ticket size of ₹50 lakh per client. Mutual funds accept far smaller amounts.

  • Saying PMS is not regulated because it is a customised service.

    Customisation sounds like a private arrangement.

    Fix: PMS is regulated by SEBI. Portfolio managers must be registered under the SEBI (Portfolio Managers) Regulations, 2020.

Worked examples

Example 1

A portfolio manager buys and sells securities in a client's account using his own judgement, without asking the client before each trade, as allowed in the agreement. Which type of PMS is this?
A) Advisory PMS
B) Discretionary PMS
C) Non-discretionary PMS
D) Mutual fund scheme

Show the solution
  1. Find the clue: the manager decides and trades without asking the client each time.
  2. Advisory PMS is out. There, the manager only advises and the client executes.
  3. Non-discretionary PMS is out. There, each transaction needs the client's prior instruction.
  4. A mutual fund is out. It pools money and issues units, and this is an individual account.
  5. Sole judgement without per-trade consent is the definition of discretionary PMS.

Answer: B) Discretionary PMS

Example 2

Which statement correctly distinguishes PMS from a mutual fund scheme?
A) Both pool investors' money and issue units at a common NAV
B) PMS keeps a separate portfolio in each client's name; a mutual fund pools money into one scheme
C) PMS has no regulator, while mutual funds are regulated by SEBI
D) PMS is only for investors who invest less than ₹50 lakh

Show the solution
  1. Test option A: only mutual funds pool money and issue units. PMS does not. So A is wrong.
  2. Test option B: it states the core difference accurately.
  3. Test option C: PMS is regulated by SEBI, so C is wrong.
  4. Test option D: the minimum investment in PMS is ₹50 lakh per client, so D is wrong.
  5. Only B matches the facts.

Answer: B) PMS keeps a separate portfolio in each client's name; a mutual fund pools money into one scheme

Exam tips

  • Learn the three PMS types by the question 'who decides and who executes'. Many MCQs are built on this.
  • Watch for scenario questions with no label. The words 'prior instruction' or 'consent for each trade' point to non-discretionary PMS.
  • For PMS vs mutual fund questions, anchor on pooling, ownership, customisation and minimum ticket size.
  • Do not guess when two options look alike. Negative marking is 10% of the marks for a question, so a wrong answer costs you.
