A mutual fund is an investment fund that collects money from many investors and invests it in a portfolio of assets such as shares and bonds. Instead of buying each security yourself, you buy units of the fund and a professional fund manager manages the portfolio for you.
How does a mutual fund work?
Think of a shared investment pot. Say 1,000 people each put ৳ 10,000 into the same fund. That makes a pool of ৳ 1 crore.
The fund manager uses the pool to buy assets that match the fund's strategy. If each unit costs ৳ 10, the fund issues 10 lakh units and each person holds 1,000 of them. When the value of the assets goes up, the value of every unit goes up with it. When the assets fall, so do the units.
Who is involved in a mutual fund in Bangladesh?
A fund isn't run by one person with a spreadsheet. Several parties each have a job.
| Party | What they do |
|---|---|
| Sponsor | Sets up the fund and brings in the initial capital |
| Asset management company (AMC) | Makes the day-to-day investment decisions |
| Trustee | Looks after the interests of unit holders and keeps an eye on the AMC |
| Custodian | Safekeeps the fund's securities |
| BSEC | Registers the fund and the parties involved and supervises the market |
What does a mutual fund invest in?
It depends on the fund's strategy. Common holdings include:
- Shares of listed companies
- Government securities
- Corporate bonds
- Other fixed-income instruments
- Cash and cash equivalents
A growth fund leans toward shares. An income fund leans toward fixed-income assets. You can read more in our guide to the types of mutual funds.
How do investors make money from a mutual fund?
There are two main ways.
- The unit price rises. If you buy at a NAV of ৳ 10 and the NAV later reaches ৳ 12, your units are worth more.
- The fund pays a dividend. Some funds distribute part of their income to unit holders, depending on their rules.
Neither is guaranteed. The unit price can fall and a fund can skip a dividend.
Mutual fund vs buying stocks yourself
| Mutual fund | Individual stocks | |
|---|---|---|
| What you own | Units of a fund that holds many securities | Shares of one company |
| Who picks the investments | A professional fund manager | You |
| Diversification | Built in | You have to build it yourself |
| Effort needed | Lower | Higher, you research and monitor each company |
| Risk | Spread out | Concentrated in the companies you pick |
A fund can give you diversification and professional management. It can't make market risk disappear.
Is a mutual fund the same as a bank deposit?
No. A bank deposit pays interest on terms agreed up front. A mutual fund's return depends on how its investments perform. We compare the two in detail in lump sum vs FDR in Bangladesh.
Frequently asked questions
Can mutual funds lose money?
Yes. The value of your units can fall below what you paid. That is why the fund's strategy and your time horizon matter.
Who manages mutual funds in Bangladesh?
Asset management companies registered with BSEC (opens in a new tab) manage them. A trustee and a custodian also have defined roles.
How much money do I need to start?
On Bini, the minimum depends on the asset manager.
- SIP, ৳ 1,000 a month: EDGE, Ekush and CWT funds.
- SIP, ৳ 2,000 a month: VIPB and Midland funds. VIPB's two unit funds do not offer a SIP.
- Lump sum, 500 units (about ৳ 5,000 to ৳ 8,200): EDGE, Ekush, CWT and Midland funds.
- Lump sum, 1,000 units (about ৳ 11,300 to ৳ 14,000): VIPB funds.
Lump-sum minimums are set in units, not taka, so the amount in taka moves with each fund's price. Figures are as of October 2026, so check the fund page for the latest.
