What Is SIP Investment?
A Systematic Investment Plan (SIP) is a disciplined investment approach where investors contribute a fixed amount regularly at predetermined intervals—monthly or quarterly. It makes investing structured, manageable, and accessible while allowing wealth to accumulate gradually over time.
In India, the term “SIP” is most associated with Mutual Funds. It became popular because it removed the stress of market timing and allowed investors to participate in equity markets without a large initial lump sum.
However, the methodology of SIP—regular, disciplined investing—is not limited to mutual funds.
It can equally be applied to Portfolio Management Services (PMS).
Before we understand how SIP works in PMS, it is important to understand how SIP evolved.
A Brief History of SIP
The concept of investing regularly is not new.
In The Intelligent Investor (1949), Benjamin Graham advocated what we now call “dollar-cost averaging”—investing a fixed sum at regular intervals irrespective of market conditions. His logic was simple: consistency reduces emotional errors and market timing risk.
In India, SIP adoption evolved gradually alongside the growth of mutual funds and improved market access. Over time, technology made systematic investing easier and more accessible to retail investors.
However, the real inflection point came with the “Mutual Fund Sahi Hai” campaign (launched in 2017), which transformed SIP from a niche investing method into a household concept. It normalized disciplined monthly investing and embedded SIP into mainstream financial behaviour.[JR1]
Today, SIP has become synonymous with disciplined investing.
Globally too, similar structures exist:
- USA: Automatic Investment Plans / DCA
- UK: Regular Savings Plans
- Germany: Sparplan
- Singapore: Regular Savings Plans
The principle is universal: invest consistently, reduce volatility impact, and allow compounding to work.
How SIP in Mutual Funds Is Different from SIP in PMS
While the philosophy of discipline remains constant, the execution differs significantly.
A. Deployment Style
Mutual Fund SIP
- Automatically invested at prevailing NAV
- Fully deployed on SIP date
- Invested irrespective of market valuations
PMS SIP
- Not mechanically deployed
- Allocation depends on valuations and opportunity
- Funds may be selectively invested or temporarily held in liquid instruments
PMS SIP
- Not mechanically deployed
- Allocation depends on valuations and opportunity
- Funds may be selectively invested or temporarily held in liquid instruments
B. Structure & Flexibility
C. Passive vs Active
Index SIP
- Replicates index composition
- No flexibility to avoid expensive sectors
- Seeks market return
PMS
- Actively selects stocks
- Adjusts exposure based on valuations
- Aims to generate alpha
D. Impact During Market Phases
In mutual funds, SIP money gets uniformly invested across the market.
In PMS, capital during corrections can be directed toward high-conviction ideas available at attractive valuations.
This brings us to the important question — how should SIP ideally be done in PMS?
The Right Framework for SIP in PMS
SIP in PMS is not about mechanical investing. It is about disciplined capital flow combined with prudent allocation.
- Prudence Over Mechanical Deployment
The objective is not to time the market, but to ensure capital is allocated thoughtfully.
Each instalment is evaluated based on:
- Existing holdings
- Current valuations
- Available opportunities
If valuations are elevated, funds may be temporarily held in liquid instruments instead of being deployed aggressively.
- Opportunity-Led Additions
During favourable phases—especially corrections—the portfolio manager may recommend incremental investments to capitalize on better risk-reward.
- Transparency & Alignment
- Clear reporting of holdings and performance
- Visibility into decision rationale
- Continuous investor-manager alignment
- Continuous Review
- Regular performance review
- Rebalancing when required
- Alignment with long-term objectives
Why Don’t People Do SIP in PMS?
Despite its advantages, SIP in PMS is underutilized. The reasons are largely behavioural and perception-driven:
- PMS is viewed as a lump-sum product
- Limited awareness about SIP in PMS
- Operational difference from NAV-based investing creates hesitation
- Many investors prefer timing markets or deploying in large chunks
However, combining discipline with active management can create meaningful long-term impact.
How SIP Works in PMS
There are two ways:
- Fixed SIP – Same amount every month
- Flexible SIP – Amount varies based on financial situation and opportunities
The key is maintaining discipline.
Now, let’s talk numbers.
Assuming a steady 12% annual return over 10 years, two investors start their PMS journey together:
- The first investor deploys ₹50 lakhs as a lump sum on Day 1 and makes no further additions. At 12% CAGR, this grows to ~₹1.55 Cr by Year 10 — a solid outcome from a one-time investment.
- The second investor follows a disciplined approach, contributing ₹1 lakh monthly and increasing the SIP by 5% every year. With step-up discipline and compounding, this investor’s corpus grows significantly more — to ~₹4.42 Cr by Year 10 (nearly 3× higher than the lump sum outcome).
The reason for this divergence isn’t a higher risk or market-timing luck — it is the combined effect of Rupee Cost Averaging, systematic investing, disciplined step-ups, and the power of compounding working on a progressively larger investment base.
The Long-Term Power of a PMS SIP (At 12%)
The 10-year example showed how disciplined investing improves outcomes.
Now extend that discipline across an entire investing lifecycle.
Starting at Age 30
If an investor:
- Invests ₹1 lakh per month
- Continues till age 60
- Earns 12% annually
Over 30 years:
- Total invested: ₹4.10 Cr (₹50L initial + ₹12L annually for 30 years)
- Final corpus: ~₹45.50 Cr
- Wealth multiple: ~11.10× of capital invested
At 12%, the journey is still powerful — but what’s more important is where the wealth actually gets created.
In the first 10 years, the corpus grows to just ~₹3.77 Cr.
By Year 20, it reaches ~₹13.94 Cr.
But in the last 10 years alone (Year 21–30), the corpus jumps from ~₹15.73 Cr to ~₹45.50 Cr.
That means:
Nearly two-thirds of the final wealth is created in the last decade.
Not because SIPs increased.
Not because risk increased.
But because compounding finally had scale to work on.
By the later years, growth is driven less by new SIPs and more by returns on the accumulated corpus.
And this is without any step-up.
If SIP is stepped up annually, the invested base rises faster, compounding acts on larger amounts earlier, and the wealth multiple expands meaningfully beyond 11×.

Conclusion: Discipline Is the Differentiator
SIP in PMS is not about replicating a mutual fund structure.
It is about combining discipline with differentiated allocation.
While mutual fund SIPs automate investing, PMS SIPs add a layer of judgement — capital is evaluated, deployed thoughtfully, and aligned with opportunity. The discipline remains systematic. The deployment becomes strategic.
Over 10 years, structure improves outcomes.
Over 30 years, compounding transforms outcomes.
What truly changes the trajectory is not market timing, not chasing returns, and not increasing risk — it is:
- Consistent capital allocation
- Staying invested across market cycles
- Allowing compounding to operate at scale
- And, when possible, gradually increasing investment capacity
The data clearly shows that most of the wealth is built in the later years — when the accumulated corpus becomes large enough for compounding to meaningfully accelerate growth.
SIP in PMS, therefore, is not just a contribution method.
It is a long-term capital-building framework.
Because in investing, consistency builds scale.
And scale, over time, builds wealth.
