The limits a fund must respect

A rulebook is only as good as its limits, and SEBI’s investment restrictions are the guardrails that stop a scheme from gambling an investor’s money on a single name. The headline limit is simple and heavily tested: a scheme may invest a maximum of 10% of its NAV in the securities of a single issuer. That cap is what makes “diversification” more than a slogan, no one company, however tempting, can be allowed to sink the fund. There are also aggregate limits across all of a fund’s schemes, so a fund house cannot quietly build an outsized stake in one company by spreading it over many schemes.

One subtlety earns marks: the restrictions are checked at the time of making the investment. If a holding later drifts above the limit purely because its price rose, that is treated differently from deliberately buying past the cap, the rule polices the decision to invest, not every market wobble afterwards. And the point of all of it is diversification and investor protection, never to cap returns.

The same spirit governs how a fund may talk about itself. Under the SEBI advertisement code, marketing must be truthful and not misleading, must never promise a guaranteed return, and must always carry the standard warning that mutual fund investments are subject to market risks and that all scheme-related documents should be read carefully. Limits on where a fund invests, and limits on what it may claim, are two halves of the same idea: keeping the investor safe from both bad bets and big talk.
