What Does a Fund Manager Do? A Guide for Listed Companies

10 Nov 2026

Few investors shape a listed company's prospects as directly as the fund manager: the professional or team responsible for making investment decisions on behalf of a fund, choosing which securities to buy, hold, and sell to meet the fund's objectives and deliver returns to its underlying investors. Whether they sit at a large asset management firm, a boutique house, or a sovereign wealth vehicle, fund managers are among the most influential holders a company can win onto its register, and engaging them well starts with understanding how they work. GEM COMM sees this relationship from both sides: it advises SGX-listed issuers, while its research desk publishes company coverage that fund managers read when forming a view. This guide answers four questions every CFO or IR officer should be able to answer before a first conversation with the buy side: what the role involves, how it differs from a portfolio manager’s, how fund managers judge a company, and what that means for engagement in Singapore.

What Does a Fund Manager Do Day to Day?

While the role is often reduced to "picking stocks", that shorthand understates how structured the work is. In practice, it divides into five recurring activities:

• Building the thesis: Every holding rests on an investment thesis, grounded in the company's fundamentals, competitive position, growth trajectory, and management quality.
• Research: Analysis is conducted in-house and supplemented by sell-side equity research and, where relevant, direct meetings with management.
• Decision-making: Buy, hold, and sell decisions are made within the constraints of its mandate, benchmark, and risk parameters.
• Monitoring: The portfolio is monitored continuously for changes in performance, strategy, governance, or market conditions that could weaken the thesis.
• Reporting: The fund's clients or unit holders expect regular reporting on performance, positioning, and outlook.

The role's discipline is as much about managing conviction and risk over time as it is about making individual calls. A company enters the portfolio on a thesis, and stays only as long as the thesis holds.

What Does a Portfolio Manager Do, and How Is It Different?

"Fund manager" and "portfolio manager" are often used interchangeably, and in many organisations they describe the same seat. Both roles centre on decisions that shape the composition of a pool of capital, balancing return objectives against risk and mandate constraints. Where a distinction exists, it turns on the structure of the capital rather than the nature of the work. Fund manager is the more common title when capital sits in a formally constituted fund, such as a mutual fund, unit trust, or hedge fund, in which investors hold units or shares. Portfolio manager is the broader term, covering segregated mandates for institutional clients, discretionary wealth portfolios, and internal capital allocation within a firm. In Singapore's asset management industry, the two titles are largely used interchangeably. For an issuer, what matters more than the label is the decision-making authority the individual carries and the type of capital they represent.

How Fund Managers Evaluate Listed Companies

Leadership teams often underestimate the rigour a fund manager brings to a first meeting. By the time management walks in, the filings have been read, the sell-side models checked, and the questions narrowed to the few that decide whether the thesis holds. Five dimensions carry most of the weight:

• Financial performance and quality cover revenue durability, margin structure, cash generation, balance sheet strength, and the sustainability of reported earnings.
• Management credibility rests on track record, communication discipline, and how reliably leadership has delivered against past guidance or stated targets.
• Strategic positioning concerns competitive advantage, market opportunity, and the coherence of the growth plan.
• Governance covers board composition, related-party transactions, disclosure practices, and whether management incentives align with shareholder outcomes.
• Valuation is weighed against peers, the sector, and the fund's own return expectations.

None of these is assessed in isolation. Fund managers decide on the aggregate impression, and a company's ability to tell its story consistently across all five is often the difference between winning conviction and being passed over. A strong balance sheet paired with guidance that has slipped twice reads as a credibility problem rather than a strength.

The Singapore Fund Manager Landscape

Singapore holds one of Asia's deepest concentrations of fund management capital, with assets under management of S$6.7 trillion at the end of 2025 according to the MAS Singapore Asset Management Survey 2025. The industry spans sovereign wealth funds, global managers with regional offices, local independents, family offices, and specialist boutiques. Most of that capital is invested outside Singapore, so an SGX-listed company competes for attention with opportunities across the region and beyond. Winning that attention starts with understanding how the local buy side is set up:

• Mandates range from Singapore-only to regional, Asian, and global, and fund managers can hold only companies that fit their mandate.
• Institutional appetite has been reinforced by the MAS Equity Market Development Programme, expanded to S$6.5 billion in 2026, which places capital with asset managers whose strategies carry significant allocations to Singapore small and mid-cap stocks.

Knowing which fund managers operate locally, what their mandates permit, and how they source ideas is the foundation of a deliberate investor engagement strategy. For SGX-listed companies prepared to engage seriously, the capital on their doorstep is a genuine asset, but proximity alone does not put a company on a fund manager’s watchlist.

Engaging the Fund Manager Community with GEM COMM

Fund manager conviction is won by companies that understand how these investors operate and engage with the discipline they expect. Structured fund manager engagement is central to GEM COMM’s services for publicly listed companies in Singapore, and it often marks the start of longer-term work. Here, an investor relations firm that already sits within the buy side’s information flow has a head start. GEM COMM’s role as a bridge between companies and the investment community rests on a research desk that tracks how fund managers consume disclosure. Each engagement opens with an Introductory Consultation and Strategic Planning Brief, which shapes the work that follows: identifying the fund managers whose mandates fit, building an equity narrative that answers their questions, and structuring the ongoing dialogue through which interest can mature into conviction. For eligible SGX-listed companies, this work can be supported through the Elevate Grant under the SGX Value Unlock Programme, for which GEM COMM is an appointed service provider. Listed companies looking to strengthen their standing with Singapore's fund manager community are welcome to get in touch with our team to discuss where that engagement should begin.
