What Is a Portfolio Management Service (PMS)?
A Portfolio Management Service (PMS) is a professional investment service where a SEBI-registered portfolio manager manages a dedicated portfolio on behalf of an investor. Unlike a mutual fund, where your money is pooled with thousands of other investors, a PMS operates through a segregated account. The underlying investments — whether direct securities or mutual fund units, depending on the type of PMS — are held in your own demat account. You own them directly.
Key Characteristics of PMS in India:
- Minimum Investment: As per SEBI (Portfolio Managers) Regulations, 2020, the minimum ticket size for a PMS is ₹50 lakhs.
- Target Audience: It is specifically designed for High Net-worth Individuals (HNIs) and Ultra-HNIs who require customised, professional oversight.
- Regulation: Every portfolio management services’ company must be registered with and regulated by SEBI (Securities and Exchange Board of India).
The Two Dimensions That Define PMS Types
Choosing a PMS isn’t just about picking a “good” manager. You need to understand how the service is structured across two independent axes:
- Axis 1: Level of Investor Control – Who makes the final call on a trade? This determines if the PMS is Discretionary, Non-Discretionary, or Advisory.
- Axis 2: Portfolio Construction Approach – What is the portfolio actually built from? This determines if you are in a Direct Equity PMS or an MF-based PMS.
A reader’s final choice involves a combination of both. For example, you could have a “Discretionary MF-based PMS” or a “Non-Discretionary Direct Equity PMS.”
Axis 1 — The Three SEBI-Recognised PMS Types
SEBI formally recognizes three structures based on who holds the decision-making authority.
1. Discretionary PMS
The portfolio manager has full authority to buy and sell securities on your behalf. While you define the investment mandate (risk appetite and goals) upfront, you do not approve individual trades.
- Best Suited For: Investors who want professional management and do not have the time or inclination to be involved in daily market decisions.
- Key Consideration: Trust is paramount here, as the manager acts independently within the agreed framework. This is the most common PMS type in India.
2. Non-Discretionary PMS
The manager recommends trades, but every transaction requires your explicit approval before execution. You retain the final say on every “Buy” or “Sell” call.
- Best Suited For: Investors who want expert guidance but prefer to stay actively involved and retain ultimate control.
- Key Consideration: This requires you to be highly responsive. If you are on vacation and miss an approval call, a lucrative market opportunity might pass you by.
3. Advisory PMS
Advisory PMS is SEBI-regulated and the advisor is a registered portfolio manager — distinct from wealth advisory or financial planning. The portfolio manager provides only investment advice. Execution is entirely your responsibility. The manager never touches your account; they provide the “what” and “when,” and you handle the “how.”
- Best Suited For: Sophisticated investors with their own execution infrastructure who just want an independent expert opinion.
- Key Consideration: This is the least common type. The investor bears all execution risk and must be disciplined enough to act on the advice.
Quick Comparison: The Control Spectrum
| Feature | Discretionary | Non-Discretionary | Advisory |
| Decision Authority | Portfolio Manager | Shared (Manager recommends, investor approves) | Investor |
| Investor Involvement | Low (Strategic) | High (Tactical) | High (Execution) |
| Execution Responsibility | Portfolio Manager | Portfolio Manager | Investor |
| Best For | Investors Seeking Fully Managed Oversight | Investors Who Prefer Active Participation | Experienced Self-Directed Investors |
| Primary Consideration | Trust in Manager | Speed of Approval | Execution Capability |
To make this concrete: picture two investors, both putting ₹1 crore into a PMS with the same manager. The first signs a Discretionary agreement — she receives quarterly reports, but the manager buys and sells without calling her first. The second signs a Non-Discretionary agreement — when the manager spots an opportunity, he calls for approval before executing. If that investor is travelling and misses the call, the trade does not go through. Same expertise, very different day-to-day experience. Which structure suits you depends less on the manager and more on how involved you actually want to be.
Axis 2 — How the Portfolio Is Built
Separate from the question of investor control, PMS strategies also differ in what the portfolio is actually built from. SEBI recognises both approaches below as valid PMS structures — neither is a workaround or an informal variant.
Direct Equity PMS
The manager builds a portfolio of individual listed stocks held in your demat account.
- Strategies: Usually focused on themes like value, growth, or concentrated “high-conviction” bets (e.g., a 15-stock portfolio).
- Risk: Higher potential for alpha, but risk is concentrated in individual stocks.
MF-Based PMS
The manager builds the portfolio using mutual fund units, not individual stocks held in your segregated demat account.
The natural question here is: why pay for a PMS when you can buy mutual funds yourself? The answer lies in what the manager actually does. A self-directed mutual fund investor typically picks a set of funds and holds them.
An MF-based PMS manager actively makes allocation decisions across fund categories — large-cap, flexi-cap, debt, hybrid — shifts between them based on market conditions, and selects specific fund houses and schemes with intent. It is active portfolio construction using mutual funds as building blocks, not passive buy-and-hold.
What You Get: The diversification structure of mutual funds with a professional actively managing the allocation above it. Like all market-linked investments, returns are subject to market risk and are not guaranteed
Comparison: Direct Equity vs. MF-Based
| Row Header | Direct Equity PMS | MF-Based PMS |
| Underlying Instruments | Individual Stocks | Mutual Fund Units |
| Customization Level | High (Stock-level exclusions) | Moderate (Category-level) |
| Strategy types | Value, growth, momentum, thematic, high-conviction | Category rotation, active fund selection |
| Diversification | Lower (Concentrated) | Higher (Multi-fund) |
| Best Suited For | Conviction-driven investors | Diversification-first investors |
Key Questions to Ask Before You Invest
- What type of PMS do you offer—Discretionary, Non-Discretionary, or Advisory?
- What is the underlying asset—direct equities, mutual funds, or both?
- What is your investment philosophy (e.g., Growth at Reasonable Price)?
- What are the exit loads and lock-in periods?
- What is your SEBI registration number and can I see some Disclosure Documents?
Conclusion
No PMS type is universally the right choice. The two-axis framework in this guide — control preference (Discretionary, Non-Discretionary, or Advisory) and construction preference (Direct Equity or MF-based) — gives you a way to evaluate any PMS product on its actual structure, not its marketing. Both axes affect your day-to-day experience as an investor.
The right fit depends on three things: how involved you want to be, how much customisation you need, and how much confidence you have in the portfolio manager’s process. Get clear on those three before evaluating any specific product, and the right questions will follow naturally.
