What a mutual fund actually is
A pooled portfolio run by a manager against a stated mandate — plus the categories, the costs, and why a low NAV means nothing.
Strip away the marketing and a mutual fund is a simple arrangement. Many investors put money into a common pool. A professional manager invests that pool according to a mandate published in advance. Everyone owns units representing their share of it, and the value of a unit rises and falls with the underlying holdings.
That is it. The complexity people encounter is not in the structure — it is in the hundreds of variations on it.
The categories, and what separates them
SEBI requires funds to be classified so that comparisons are meaningful. The distinction that matters most is what the fund is allowed to hold.
| Type | Holds | Reasonable expectation | Suits | | --- | --- | --- | --- | | Equity | Company shares | Highest long-run growth, large swings | 7+ year goals | | Debt | Bonds, government securities | Modest, far steadier | 1–3 year goals | | Hybrid | A mix of both | Between the two | Middle horizons | | Index | Whatever the index holds | Matches the index, minus a small cost | Long-term core holdings |
Within equity there are further splits by company size — large cap, mid cap, small cap — and by style. Smaller companies have historically produced higher returns with considerably larger drawdowns. A fund holding small caps can fall 50% in a bad year, and that is inside its normal range of behaviour, not a malfunction.
Direct plans, and the cost that compounds against you
Every fund is sold in two versions of the identical portfolio.
- A regular plan pays a commission to whoever sold it to you, taken out of the fund every year.
- A direct plan has no distributor, so that commission is not deducted.
The difference in expense ratio is usually between 0.5% and 1% a year. That sounds negligible. It is not, because you pay it on the whole balance every year, including the returns it prevented you from earning.
On a ₹10,000 monthly SIP over 25 years at 12%, a 1% higher expense ratio costs several lakh rupees by the end. The portfolio is the same. The manager is the same. The only difference is who receives that slice.
The catch is that direct plans require you to choose the fund yourself, which is exactly what the rest of these lessons are for.
Reading a factsheet
Every fund publishes a monthly factsheet. Four things on it are worth your attention:
- Expense ratio — the annual cost, already deducted from returns.
- Top holdings — what you actually own. Two differently-named funds frequently hold the same ten companies.
- AUM — the size of the fund. Very large small-cap funds can struggle to enter and exit positions cleanly.
- Exit load — a charge for redeeming early, typically 1% within a year.
What deserves far less attention is the past-returns table, which is the most prominent thing on the page. Last year's winner is routinely next year's laggard, and the fund is legally required to tell you so.
The NAV misconception
This one costs people real money, so it is worth being blunt.
A fund with an NAV of ₹15 is not cheaper than one with an NAV of ₹300. NAV is simply the current value of one unit. ₹30,000 buys 2,000 units of the first or 100 units of the second, and both are worth ₹30,000. If each portfolio grows 10%, both positions become ₹33,000.
A low NAV tells you the fund is newer, or has paid out more, or split its units. It tells you nothing whatsoever about whether it is a good investment. New Fund Offers are frequently marketed at ₹10 a unit for exactly this reason — the number feels like a bargain, and it isn't one.
Once you can read a factsheet and spot the direct plan, you have most of what you need to choose sensibly. The next question is how to put money in: start with SIPs →
