The People Behind Your SIP: Role of Fund Managers in Mutual Funds

What Does a Fund Manager Actually Do?

A fund manager is a finance professional who makes investment decisions on behalf of investors in a mutual fund scheme. When you invest ₹5,000 in a flexi-cap fund via SIP, you are handing those ₹5,000 to someone who decides which stocks or bonds to buy, when to buy, how much to hold, and when to exit. Their core responsibilities under SEBI (Mutual Funds) Regulations, 1996 include,

• Stock selection - Identifying companies worth investing in through fundamental research, studying balance sheets, meeting management teams and assessing competitive positioning.
• Portfolio allocation - Deciding how much of the fund's corpus goes into each stock or sector, ensuring no single bet dominates the portfolio unnecessarily.
• Risk management - Keeping the portfolio diversified, monitoring concentration limits, and ensuring the fund stays within the risk parameters defined in its Scheme Information Document (SID).
• Rebalancing - Periodically adjusting holdings based on changing valuations, business performance, or macro conditions, trimming positions that have become too large and adding to those with better prospects.
• Benchmark accountability - Every scheme is measured against a defined benchmark, the Nifty 50, Nifty 500, or a category-specific index. The fund manager's primary job is to beat that benchmark consistently over the long term, net of fees.

Who Becomes a Fund Manager?

Most fund managers hold postgraduate degrees from institutions like the IIMs, combined with CFA or CA qualifications. They usually spend years as equity research analysts, developing deep sector expertise in areas like banking, technology, or pharmaceuticals before being assigned fund management responsibility. Many come from the buy side, meaning they have always worked within AMCs evaluating stocks to invest in. Others transition from the sell side, investment banks or brokerages where they produced research for institutional clients. Both backgrounds bring value: sell-side experience adds breadth of market coverage, while buy-side experience builds portfolio construction discipline. SEBI mandates that fund managers of equity schemes have adequate investment management experience before being assigned a scheme. AMCs maintain internal qualification standards above and beyond this regulatory floor.

The Names That Built Investor Trust

A handful of fund managers in India have built reputations strong enough that investors follow them by name. Prashant Jain, formerly CIO at HDFC Mutual Fund for nearly two decades, grew the fund house's AUM from ₹3,000 crore to ₹4.4 lakh crore and delivered approximately 17.9% CAGR on the HDFC Balanced Advantage Fund against the Sensex's 9.6% over the same period. Sankaran Naren at ICICI Prudential currently manages 12 schemes with a combined AUM of over ₹2.1 lakh crore, known for his contrarian, value-oriented approach across market cycles. These are not just fund managers, they became institutions in themselves.

Should You Invest by Fund Manager or Fund Philosophy?

Fund philosophy first, fund manager second. A fund manager can leave an AMC at any time. When Prashant Jain left HDFC in 2022, many investors were unsure whether to stay or exit. The smarter question was whether the fund's underlying investment philosophy and process had changed — not just the name on the door. Invest in a scheme whose mandate you understand and agree with. A flexi-cap fund that takes concentrated high-conviction bets behaves very differently from one that stays diversified across 80 stocks. Know what you are signing up for before you sign up. That said, fund manager continuity does matter — a track record belongs to both the process and the person running it.

How to Find Information About Fund Managers

This information is more accessible than most investors realise. Every scheme's Scheme Information Document and Key Information Memorandum, available on the AMC website and at amfiindia.com, names the fund manager, their qualifications, and other schemes they manage. SEBI mandates disclosure of fund manager details in all scheme documents, and any change must be reported by the AMC within one working day. Monthly factsheets published by AMCs provide portfolio holdings, benchmark comparison, and fund manager commentary. Platforms like Value Research Online and Morningstar India publish fund manager profiles including tenure, scheme history, and risk-adjusted returns. Portfolio turnover ratio also disclosed in factsheets tells you how frequently the manager churns the portfolio. High turnover means higher transaction costs and potentially higher tax drag on returns.

How to Evaluate a Fund Manager Before Investing

Use this checklist before committing to any actively managed scheme.

• Tenure - Has the manager run this specific scheme for at least five years? Track records shorter than that span too few market cycles to be meaningful.
• Consistency vs benchmark- Does the fund beat its benchmark regularly, not just in one strong year? Check rolling 3-year and 5-year returns against the stated benchmark.
• Drawdown behaviour - How much did the fund fall during the 2020 COVID crash or 2022 rate hike cycle? A manager who protects capital during downturns adds more long-term value than one who only performs in bull markets.
• Style consistency - Does the fund stay true to its stated mandate? A large-cap fund that drifts into small-caps during a rally is not following its SID, a red flag for process discipline.
• Expense ratio - Actively managed funds in India typically charge 1.0 to 2.25% annually. This fee is deducted from returns before you receive them. A manager needs to beat the benchmark by more than the expense ratio to actually add value.
• When to exit due to a manager change: If a long-tenure manager with a strong track record leaves, do not exit immediately. Wait one quarter, assess whether the investment philosophy has changed, check whether the new manager has relevant experience, and review the first portfolio disclosure under the new manager before deciding.

Importance of Choosing the Right Fund Manager

Data from the SPIVA India Scorecard shows that a significant proportion of funds, especially in large-cap categories, have historically found it challenging to outperform their benchmarks over long periods. This reflects the efficiency of large-cap markets, where information is widely available and pricing is highly competitive. However, the picture is more nuanced across categories. In segments like mid- and small-cap funds, where market inefficiencies are higher and research coverage is relatively limited, skilled fund managers have demonstrated a greater ability to generate alpha. Even in recent periods such as H1 2025, these categories have seen broader outperformance compared to large caps. What this means for investors is not that fund managers lack value, but that their impact varies by category. In efficient segments like large caps, low-cost index investing can be effective. In less efficient segments, the role of an experienced fund manager becomes significantly more important in identifying opportunities and managing risk.

Frequently Asked Questions

What does a mutual fund manager do?

Selects stocks, manages portfolio allocation, controls risk and aims to beat the scheme's benchmark over the long term within the framework defined in the SID.

Should I invest based on the fund manager or the fund philosophy?

Fund philosophy first. A scheme's mandate and process outlast any individual. Evaluate whether the process changed when a manager leaves, not just the name.

How do I check a fund manager's performance?

Through AMC factsheets, amfiindia.com, Value Research Online and Morningstar India. Check rolling returns against the benchmark across multiple periods, not just the most recent year.

What is a good fund manager tenure?

At least five years on the same scheme. This spans at least one market cycle and gives a more reliable picture of performance under different conditions.

Do actively managed funds outperform index funds in India?

Not consistently in large-cap. SPIVA data shows 73% of large-cap funds underperformed their benchmark over 10 years. Mid and small-cap active funds have a better record of outperformance due to less efficient markets in those segments.

What is alpha and why does it matter?

Alpha is the return a fund generates above its benchmark. A fund with 2% alpha has outperformed its benchmark by 2 percentage points. Beta measures how much the fund moves relative to the market, a beta of 1.2 means the fund rises or falls 20% more than the index. A good active manager ideally delivers positive alpha without taking on excessive beta.
