Direct Investment, Co-Investment, and Fund Investment Methods

Updated for the 2026 CFA® Level I curriculum.

Investors can access alternative investments in three ways: directly, alongside a fund through co-investment, or indirectly through a fund. Each method changes who controls the asset, who performs due diligence, and how much it costs to participate. CFA Level I often presents an investor case describing resources, control needs, and time constraints. Match those facts to the most suitable access method.

Key Takeaways

• Fund investment gives decision-making authority to a manager, who selects and oversees every underlying asset in the pool.

• Direct investment gives the investor full control but requires internal expertise, sourcing capability, and governance capacity.

• Co-investment is a hybrid. The investor gains deal-level access through a fund sponsor's pipeline, then invests directly in that single deal.

• Fees typically decrease as investor involvement increases, but internal staffing and oversight costs can offset those savings.

• Fund investment offers the most diversification per dollar committed. Direct and co-investments concentrate risk in individual deals.

• Due diligence burden rises as an investor moves from fund investment toward co-investment and direct investment.

• Choosing among the three methods depends on the investor's capital size, staff expertise, and governance capacity, not on a universal ranking.

What You Need to Know for CFA Level I

• Define direct investment, co-investment, and fund investment from the investor's point of view.

• Compare the three methods on control, required expertise, due diligence, fees, diversification, minimum investment size, and speed of deployment.

• Explain why co-investment combines features of both direct and fund investing.

• Recognize fund investment as an indirect, pooled approach where a manager makes the underlying decisions.

• Select the most suitable method from an investor fact pattern using stated constraints, not assumed superiority.

How Fund Investment Works

Fund investment is the most common way individual and institutional investors access alternative investments. The investor commits capital to a fund. A general partner or investment manager then sources, selects, and manages the underlying investments on the investor's behalf.

This structure gives the investor indirect exposure. The investor never selects individual deals and typically has limited say in day-to-day decisions. In exchange, the investor gains diversification across many underlying investments, professional sourcing and due diligence, and access to opportunities that would otherwise require far more capital or expertise to reach alone.

The cost of this convenience shows up as management and performance fees. Control also shifts almost entirely to the manager. An investor who lacks the staff or time to evaluate individual deals often finds fund investment the most practical entry point.

How Co-Investment Works

Co-investment lets an investor commit directly to a specific deal alongside a fund sponsor, rather than committing to the fund's entire portfolio. The fund sponsor identifies the opportunity and often leads the transaction. The co-investor then commits capital directly into that single deal, outside the main fund vehicle.

This structure gives the investor more deal-level choice than a standard fund commitment. Because the co-investment sits outside the fund's fee structure, investors sometimes negotiate reduced fees on the co-invested portion. Some sponsors offer co-investment specifically to attract additional capital from existing fund investors without diluting the sponsor's own economics.

The tradeoff is concentration and speed. A co-investment exposes the investor to a single deal rather than a diversified pool. Sponsors also typically offer co-investment opportunities on short timelines, so the investor needs enough internal due diligence capacity to evaluate a specific deal quickly.

Responsibility Split in Co-Investment

How Direct Investment Works

Direct investment means the investor identifies, acquires, and manages the underlying asset without a fund intermediary. The investor performs its own sourcing, negotiates terms, and takes on governance responsibilities, such as board representation in a private equity direct deal.

This method offers the highest level of control. The investor decides which assets to acquire, how to structure the investment, and how to manage it over time. There is no manager fee layer, which can reduce costs.

Those savings depend on the investor having the internal resources to replace what a fund manager would otherwise provide. Direct investment demands significant capital, a skilled internal team, strong sourcing networks, and the governance capacity to oversee the asset directly. Without those resources, the apparent fee savings can be outweighed by weaker sourcing, poor due diligence, or concentration in too few positions.

Direct Investment vs Co-Investment vs Fund Investment

The three methods sit on a spectrum. Fund investment transfers nearly all decision-making to a manager. Direct investment keeps every decision with the investor. Co-investment blends the two: the sponsor sources the deal, but the investor decides whether to commit directly.

Worked Example

Three institutions are each deciding how to add private equity exposure.

Institution A is a small pension fund with three investment staff. It wants broad diversification across many portfolio companies and has no internal deal-sourcing capability.

Institution B is a large sovereign wealth fund with a 20-person private equity team, strong sourcing relationships, and a mandate to build concentrated, long-term positions.

Institution C already holds a commitment in a mid-market buyout fund. The fund's general partner offers Institution C a chance to co-invest directly in one portfolio company, with a two-week window to decide.

Reasoning

Institution A lacks staff and sourcing capability. Fund investment fits best because it outsources selection and due diligence while spreading capital across many deals.

Institution B has the staff, capital, and governance capacity to manage direct positions. Direct investment fits because the institution can replace the manager's role internally and avoid layered fees.

Institution C already has a sponsor relationship and some due diligence infrastructure from its existing fund commitment. The short timeline and single-deal nature point to co-investment. Institution C gains deal-level exposure and potential fee savings, but takes on concentration risk in that one company.

Suitability depends on each institution's staff, capital, sourcing capability, and timeline, not on any single method being superior.

Common Exam Traps

Treating co-investment as identical to a standard fund commitment

Co-investment involves a specific deal, not the fund's full diversified portfolio. Exam stems that mention a single opportunity and a short decision window point toward co-investment, not a standard fund allocation.

Assuming direct investment is always cheaper after internal costs

Direct investment avoids manager fees, but the investor absorbs sourcing, staffing, and governance costs internally. A stem describing limited internal resources should not default to direct investment just because it lacks a management fee.

Ignoring concentration risk in a single direct or co-investment

Both methods reduce diversification compared to a fund. Do not treat control as a benefit without weighing the added concentration.

Assuming fund investing provides investor-level control over each asset

Fund investors delegate decision-making to the manager. A stem asking about control over a specific holding rules out fund investment.

Choosing a method without using the investor's expertise and governance constraints

The correct answer depends on the facts given about staff, capital, and time, not on a general preference for more control.

Practice Question

An insurance company holds a limited partnership interest in a private equity fund. The fund's general partner offers the insurer a chance to invest directly in one portfolio company alongside the fund, at reduced incremental fees. The insurer has a small due diligence team and only ten business days to decide.

Which investment method does this opportunity most likely represent?

1. Fund investment, because the insurer already holds a limited partnership interest.

2. Co-investment, because the insurer can invest directly in a specific deal alongside the fund sponsor.

3. Direct investment, because the insurer is investing outside the fund's main vehicle.
