Mutual Funds, PMS, and AIFs all play a role in investor portfolios—but they are not built the same.
This whitepaper explains how differences in structure, fund manager alignment, and continuity can materially impact long-term investment outcomes, and why owner-managed PMS/AIFs often stand out.

Mutual Funds, Portfolio Management Services (PMS), and Alternative Investment Funds (AIFs) are all regulated investment structures, but they are designed with very different objectives in mind. Mutual Funds are built for scale, accessibility, and ease of participation, while PMS and AIF structures offer greater flexibility, customization, and the ability to run focused, high-conviction strategies.
This whitepaper explores these differences in a practical, investor-centric way. It explains how structural factors such as pooling versus segregated accounts, taxation timing, and operational flexibility influence portfolio construction and long-term outcomes. Rather than treating these as technical details, the paper highlights why they matter in real-world investing.
A central theme of the paper is fund manager alignment and continuity. In large mutual fund setups, fund managers operate as employees within institutional frameworks, often leading to manager churn over time. For investors, this can dilute the original investment philosophy without it being immediately obvious. Owner-managed PMS and AIF platforms, by contrast, tend to offer greater stability, long-term accountability, and a tighter link between philosophy and execution.
The paper also examines long-term performance data across market segments, showing that PMS strategies—particularly those run with high conviction and clear philosophies—have delivered superior outcomes over extended periods, even after fees. This outperformance is not limited to smaller market segments but is visible across large-cap, flexi-cap, and mid-cap strategies as well.
Importantly, the whitepaper does not position this as an either-or choice. Mutual Funds remain essential for liquidity, diversification, and systematic investing. However, for investors seeking deeper engagement with investment philosophy, stronger manager alignment, and the potential for higher-quality long-term outcomes, owner-managed PMS and AIFs can play a valuable complementary role within a well-constructed portfolio.
