For years, the standard argument in favour of portfolio management services (PMS) has been simple—concentrated portfolios and active stock picking can deliver higher returns than mutual funds. However, as mutual funds have grown more sophisticated, offering factor strategies, sectoral funds and passive products, investors are asking a tougher question: What can a PMS do that a mutual fund cannot?
The answer is structural. A PMS can hold fewer than 20 stocks with very high concentration levels, sit on huge piles of cash when a manager sees no opportunity, or build a fixedincome portfolio around one client’s tax situation. It can also invest in corners of the market that large funds have effectively outgrown: micro-cap companies where even a small allocation would swallow a significant chunk of tradeable shares, or heavily focused on listed real assets through REITs (Real Estate Investment Trusts) and InvITs (Infrastructure Investment Trusts).

The strategy menu

R. Pallavarajan, Founder of PMS Bazaar, a PMS research and distribution platform, provides a lowdown on differentiated strategies that fall outside the mutual fund structure entirely. “Unlike mutual funds, PMS managers have the flexibility to run concentrated portfolios, take meaningful active cash calls, and customise portfolios at the client level. This allows them to pursue investment strategies that may not be practical within a mutual fund framework, particularly where liquidity, concentration, or portfolio customisation is involved.”

ETF-based PMS strategies construct portfolios predominantly using ETFs to enable tactical asset allocation and factor-based strategies. Mutual Fund PMS products use mutual funds as building blocks while layering active allocation and dynamic rebalancing on top. The strategies focused on REITs and InvITs offer dedicated, yield-oriented exposure to listed real assets, an asset class with no equivalent in the standard mutual fund catalogue. SME-focused strategies target segments that remain largely inaccessible through mutual funds due to liquidity and scale constraints.

Debt PMS products offer customised fixed-income portfolios calibrated to individual duration, credit quality and tax needs, something standardised debt funds cannot provide. At the equity end, deeply concentrated mandates hold fewer than 20 stocks, placing them in a category with no mutual fund parallel. “The differentiation in PMS,” says Pallavarajan, “is often less about finding entirely new asset classes and more about the ability to implement niche themes, concentrated strategies, tactical allocation decisions, and customised portfolio construction in ways that are not feasible within the mutual fund structure.

The micro-cap edge

Perhaps the most discussed structural advantage of PMS is its access to micro-cap and small-cap opportunities that large mutual funds have been priced out of by their own scale. Gurvinder Juneja, Principal Officer of Fortuna Asset Managers, spells it out: “A company with a Rs.600 crore market capitalisation and 45% public float has roughly Rs.270 crore of tradeable shares. A Rs.400 crore PMS taking a 3% position needs Rs.12 crore, which is achievable. A Rs.6,000 crore mutual fund taking the same position would need Rs.180 crore, 67% of the entire free float. This would move the stock against the fund’s own entry. Discipline about AUM is, at its core, a form of fiduciary responsibility.”
