What "collective" means
A collective investment vehicle pools money from many investors and invests it together. Each investor owns a share of the pool. The workbook covers four:
- Mutual funds
- Real Estate Investment Trusts (REITs) — the workbook writes "ReITs"
- Infrastructure Investment Trusts (InvITs)
- Alternative Investment Funds (AIFs)
As a PMS distributor you need to know these well. Your clients will compare PMS with each of them.
6.1.1 Mutual funds
A mutual fund is a professionally managed vehicle that pools money from many investors and invests in a diversified portfolio — stocks, bonds, money market instruments and other assets. Experienced fund managers decide, based on the fund's objectives, risk profile and market conditions.
Investors buy units. Each unit is a share of the pool. The value of units is the Net Asset Value (NAV), calculated daily.
Mutual funds serve wealth creation, income generation and capital preservation.
Eight roles mutual funds play for investors:
| Role | What the workbook says | |
|---|---|---|
| A | Diversification and risk reduction | Many securities across sectors; hard for a small investor to do alone |
| B | Professional management | Qualified managers track markets so retail investors need not |
| C | Accessibility and affordability | SIPs from as little as ₹500 per month |
| D | Liquidity and flexibility | Redeem any time — except close-ended funds — subject to exit load |
| E | Tax efficiency | Section 80C for ELSS; favourable LTCG tax on equity funds |
| F | Variety | Equity, debt, hybrid, index funds and ETFs |
| G | Transparency and regulation | Regulated by SEBI; regular reports, disclosures, NAV updates |
| H | Economies of scale | Lower transaction costs, lower expense ratios than investing directly |
6.1.2 Real Estate Investment Trusts
REITs let investors gain exposure to income-generating real estate without owning property directly. They pool money into commercial real estate — offices, malls, warehouses, hotels — that earns rent. They must distribute a significant portion of earnings to unit holders.
In India, REITs are regulated by SEBI under the SEBI (Real Estate Investment Trusts) Regulations, 2014. They are structured as trusts and must be listed on stock exchanges.
Features: accessibility without large capital; stable income from rent; liquidity through exchange trading; regulation and transparency; and an inflation hedge, as real estate typically appreciates.
6.1.3 Infrastructure Investment Trusts
InvITs pool money into infrastructure — roads, highways, power transmission lines, renewable energy projects. They let developers monetise infrastructure assets and give investors stable income.
Regulated under the SEBI (Infrastructure Investment Trusts) Regulations, 2014. Structured as trusts and must be listed.
Features: stable income from toll collections, electricity tariffs and other infrastructure revenue; access to large projects; liquidity on exchanges; regular disclosures; and inflation hedge and capital growth.
Notice both REIT and InvIT regulations are from 2014.
6.1.4 Alternative Investment Funds
AIFs are privately pooled vehicles that invest in non-traditional assets — private equity, venture capital, hedge funds, real estate, distressed assets, structured debt.
They target HNIs, institutional investors and sophisticated investors.
Features: diversification beyond traditional assets; higher return potential through customised strategies; seasoned professional managers; structured risk management; and choice of fund by risk appetite, horizon and return expectations.
6.2 Legal structure — all four are trusts
| Vehicle | Key participants |
|---|---|
| Mutual fund | Sponsor (sets up, contributes initial capital); Trust and trustee company (holds assets in fiduciary capacity, ensures compliance); AMC (investment manager); Custodian (holds securities); RTA (investor records and transactions) |
| REIT | Sponsor (sets up, holds a minimum stake as per SEBI norms); REIT trustee (compliance, oversees the manager); Investment manager (portfolio, acquisitions, operations); Custodian; Valuer (independently values the property) |
| InvIT | Sponsor (sets up, contributes capital); InvIT trustee (acts for investors, monitors the manager); Investment manager; Project manager (operates and maintains the projects); Custodian and valuer |
| AIF | Sponsor (sets up and contributes); Fund manager (investment decisions, risk, portfolio); Trustee (oversees in investors' interest); Custodian |
The participant unique to InvITs is the project manager — someone has to actually run the toll road or the power line. REITs and InvITs both have a valuer to value their assets independently.
6.3 Types of mutual funds
The workbook gives a simplified classification. It says this is for general understanding only — SEBI has its own detailed categorisation of schemes.
| Category | Risk tag in workbook | Examples |
|---|---|---|
| Equity | High risk, high return | Large-cap (established companies); mid-cap and small-cap (high-growth); sectoral / thematic (e.g. IT, pharma); ELSS (tax-saving, Section 80C) |
| Debt | Low risk, stable income | Liquid (short-term instruments); corporate bond (company bonds, moderate returns); gilt (government securities) |
| Hybrid / balanced | Blend | Aggressive hybrid — higher equity; conservative hybrid — higher debt |
| Passive | — | Index funds track indices like NIFTY 50 and Sensex; ETFs trade on stock exchanges |
Factor funds (smart beta)
Factor funds, also called smart beta funds, build portfolios using quantitative factors like value, momentum or volatility. Stock selection and weights follow mathematical rules.
They sit between active and passive. The rule-based approach is passive-like. The frequent systematic selection of stocks is active-like.
| Factor | Picks stocks with | When it tends to do well |
|---|---|---|
| Momentum | Strong upward price trends | Bull markets; carries volatility and correction risk |
| Low volatility | Lower price fluctuations | Robust in downturns, reduces drawdowns |
| Value | Low P/E, low P/B, high dividend yield (Graham and Buffett principles) | Recovery phases and bull markets |
| Quality | Low debt, stable earnings growth | Bear markets |
Some funds combine factors in two-factor or multi-factor strategies.
Types of REITs
| Type | Invests in | Earns |
|---|---|---|
| Equity REIT | Commercial properties it owns and manages | Rent |
| Mortgage REIT | Real estate loans and mortgage-backed securities | Interest |
| Hybrid REIT | Both | Rent and interest |
Types of InvITs
| Type | Key point |
|---|---|
| Public | Listed (NSE, BSE); open to retail and institutions; liquid |
| Private | Unlisted, privately placed; institutional investors only; long-term financing |
| Full-fledged | Operational, revenue-generating assets; lower risk |
| Developmental | Under-construction projects; higher risk, potential capital appreciation |
The three AIF categories
Category I — socially and economically beneficial. Early-stage businesses, social ventures, infrastructure. Examples: venture capital funds, angel funds, social venture funds, infrastructure funds. The workbook says SEBI encourages these funds by offering tax incentives.
Category II — private equity and debt. Private equity, structured debt, distressed assets. Examples: PE funds, debt funds (corporate bonds, mezzanine debt, distressed loans), fund of funds (invest in other AIFs). They receive no government incentives but have flexible mandates.
Category III — hedge funds and high-risk strategies. Complex trading — short-selling, derivatives, leverage. Examples: hedge funds (long-short, options, arbitrage) and quantitative funds (algorithmic, data-driven).
Beyond the book
India's first listed REIT, Embassy Office Parks REIT, listed in April 2019. The first listed InvIT, IRB InvIT Fund, listed in May 2017. Before them, the only way for most Indians to own a piece of a Grade-A office park or a toll road was not to own it at all.
Think of it like this
A mutual fund is a housing society's bulk gas booking
One family ordering a single cylinder pays full delivery charges. Two hundred flats booking together get a better rate, one delivery van, and a society manager who handles the paperwork.
A mutual fund works the same way. Pooling money from thousands of investors brings economies of scale — lower transaction costs per investor and a professional manager. A small investor with a ₹500 SIP gets the same manager and the same bargaining power as someone investing lakhs.
A REIT is owning a slice of a mall without buying a shop
Buying a shop in a busy mall might cost crores, and you would have to find a tenant, collect rent and fix leaks yourself.
With a REIT, you buy units on the stock exchange. The trust owns the mall, the investment manager runs it, a valuer checks what it is worth, and you get your share of the rent. If you need your money back, you sell units on the exchange instead of waiting months for a buyer — the liquidity real estate normally lacks.
Full-fledged and developmental InvITs are a running bus route and a new metro line
Investing in a bus route that already runs full every day is predictable: tickets come in, you know roughly what you will earn. Investing in a metro line still under construction is riskier — delays, cost overruns — but if it opens and the city grows around it, the value could rise a lot.
A full-fledged InvIT is the running bus route: operational assets, stable tolls or tariffs, lower risk. A developmental InvIT is the metro under construction: higher risk, with potential capital appreciation once projects become operational.
A factor fund is a cricket selector using fixed statistics
An old-style selector picks players on gut feeling — that is active management. A lazy selector just picks the same XI every match — that is passive.
Now imagine a selector who uses a fixed rule: "pick the six batsmen with the best strike rate over the last ten matches, recheck every series." The rule never changes (passive-like), but the team changes regularly (active-like). That is a factor fund: rule-based, yet systematically reselecting — which is why the workbook places it between active and passive.
