Definition
Asset allocation in the context of SEBI's mutual fund categorisation framework refers to the prescribed minimum and maximum percentage exposure that a scheme must maintain in each asset class (equity, debt, cash equivalents, REITs/InvITs, gold, international securities, etc.) as defined in its Scheme Information Document (SID). SEBI's landmark October 2017 circular (SEBI/HO/IMD/DF3/CIR/P/2017/114) standardised MF categories across all AMCs: each AMC may operate only one scheme per category, and each category has defined allocation guardrails. For example, a Large Cap Fund must invest at least 80% in large-cap stocks (top 100 by market cap as defined by AMFI's list updated semi-annually). These are not suggestions — breaching the allocation band is a regulatory violation.
SEBI Category Allocation Thresholds
Key allocation mandates from SEBI's October 2017 circular:
| Category | Min Equity % | Max Equity % | Key Constraint |
|---|---|---|---|
| Large Cap Fund | 80% | 100% | 80% in top-100 stocks only |
| Mid Cap Fund | 65% | 100% | 65% in 101st–250th stocks only |
| Small Cap Fund | 65% | 100% | 65% in 251st+ stocks only |
| Multi Cap Fund | 75% | 100% | Min 25% each in large/mid/small cap |
| Flexi Cap Fund | 65% | 100% | No sub-category minimum; manager's discretion |
| Balanced Advantage/DAA | 0% | 100% | Dynamic; model-driven; min 65% equity for equity taxation |
| Conservative Hybrid | 10% | 25% | 75–90% in debt instruments |
Portfolio Drift and Rebalancing Obligation
Market movements cause a scheme's actual allocation to drift from its SID mandate. SEBI requires AMCs to rebalance within 30 days (for most equity categories) when a mandatory threshold is breached. For example, if a Large Cap Fund's large-cap exposure drops to 78% due to mid-cap outperformance, the fund manager must buy additional large-cap stocks or sell mid-cap positions within 30 days. Failure to rebalance within prescribed windows is a regulatory breach reportable to SEBI by the Trustee.
Why It Matters for Investors
- Mandate adherence: Allocation mandates prevent "style drift" — a large-cap fund secretly holding mid/small-cap stocks to juice returns at higher risk. SEBI's rules bind the manager to the category's risk profile.
- Taxation implications: A balanced advantage fund that maintains <65% equity falls below the threshold for equity fund tax treatment, triggering debt fund taxation (slab rate for gains regardless of holding period post-Finance Act 2023).
- Rebalancing triggers sell events: When the fund rebalances to restore allocation, it sells appreciated assets — creating taxable capital gains inside the scheme (captured in NAV, not directly taxable to investors until redemption).
Worked Example
Consider Kotak Flexicap Fund (Flexi Cap category). Its SID mandates ≥65% equity with no sub-category floors. On 1 Jan, the portfolio is 72% equity, 28% debt/cash. A bull market rally pushes equity to 85% by 30 Jun. The fund manager need not rebalance (still within SID limits). But if a new investor joins expecting 72/28 allocation (as disclosed in the recent factsheet), they are now entering at 85% equity — higher risk than the historical average. This is why SEBI requires monthly factsheet disclosure of actual allocation so investors can monitor drift relative to the SID mandate.
