Rebalancing & Portfolio Review — When & How
Definition
Portfolio rebalancing is the process of realigning the portfolio's asset allocation back to the target allocation when market movements cause it to drift beyond acceptable thresholds. For example, if a Moderate portfolio's target is 55% equity and 45% debt, but a strong equity rally pushes the actual allocation to 65% equity and 35% debt, rebalancing involves shifting 10% from equity back to debt. The two primary rebalancing approaches are calendar-based rebalancing (reviewing and adjusting on a fixed schedule, typically annually) and threshold-based rebalancing (rebalancing whenever any asset class drifts by more than 5-10% from target). In mutual fund portfolios, rebalancing is executed through switch transactions (redemption from overweight category and simultaneous purchase in underweight category), which have tax implications.
In Simple Words
Rebalancing is often counter-intuitive because it requires selling what has performed well and buying what has underperformed. After a great equity bull run, the advisor is telling the client to move money FROM equity (which has given 25% returns) TO debt (which gave 7%). Every fibre of the client's being will resist this. Yet disciplined rebalancing has consistently been the single biggest differentiator between portfolios that survive market cycles and those that get destroyed. Rebalancing works for two key reasons: 1. It enforces "buy low, sell high" systematically. When equity rallies, rebalancing forces profit-booking and parking gains in debt. When equity crashes, rebalancing forces deployment of debt money into equity at lower prices. Over a full cycle, this adds 1-2% CAGR to portfolio returns compared to buy-and-hold. 2. It maintains risk control. A portfolio that started at 60% equity can become 80% equity after a 2-year bull run. At 80% equity, the portfolio will fall much harder in a correction than the client originally signed up for. Rebalancing prevents risk drift. Calendar-Based Rebalancing: A fixed date every year — April (after financial year end) or January (new year review) is recommended. On this date, actual allocation is compared with target allocation. If any asset class has drifted by more than 5%, rebalancing is triggered. This approach is simple, disciplined, and removes emotion from the decision. The downside is that rebalancing opportunities may be missed if a major market move happens mid-year. Threshold-Based Rebalancing: A threshold of ±5-10% is set, and rebalancing occurs whenever any asset class breaches it. If target equity is 60% and actual goes above 65% or below 55%, rebalancing is triggered immediately. This is more responsive but requires more frequent monitoring. The recommended practical approach is to combine both: monitor thresholds quarterly but conduct a comprehensive review annually. Critical Tax Consideration: In mutual funds, rebalancing means executing a switch (which is a redemption + fresh purchase). The redemption triggers capital gains tax. Equity fund switches after 1 year attract 12.5% LTCG (above ₹1.25 lakh exemption). Equity switches within 1 year attract 20% STCG. Debt fund gains are taxed at slab rate regardless of holding period. The tax impact must always be considered before executing — small allocation drifts (2-3%) may not justify the tax cost of rebalancing. When NOT to Rebalance: (1) When the drift is small (under 5%) — transaction costs and taxes outweigh the benefit. (2) When the client is within 1-2 years of a goal — at this point, de-risking toward debt is appropriate, not rebalancing back to equity. (3) In a systematic, prolonged correction where catching the exact bottom is impossible — rebalancing in tranches over 2-3 months is better than a one-shot switch. Annual Review Checklist for Distributors: 1. Compare actual allocation vs target — rebalance if drifted >5% 2. Review each fund's performance vs benchmark and category peers 3. Check if any fund manager changes have occurred 4. Assess if the client's goals or financial situation have changed 5. Increase SIP amounts in line with income growth (step-up) 6. Review insurance adequacy (especially after life events) 7. Tax harvest — book ₹1.25 lakhs LTCG annually tax-free if applicable 8. Document the review discussion and actions taken
Real-Life Scenario
Consider the case of Sanjay Mehta, 45, who has a Moderate portfolio set up 2 years ago with target allocation: 55% equity, 35% debt, 10% liquid/gold. Portfolio value: ₹38 lakhs. It is April — annual review time. After a strong equity rally, the actual allocation has drifted to: Equity: ₹24.7 lakhs (65%), Debt: ₹10.6 lakhs (28%), Liquid/Gold: ₹2.7 lakhs (7%). Equity has drifted 10% above target — rebalancing is clearly needed. Rebalancing Action: Target equity: 55% of ₹38 lakhs = ₹20.9 lakhs Current equity: ₹24.7 lakhs Excess equity: ₹3.8 lakhs — switch this from equity to debt funds Tax Calculation: The ₹3.8 lakh switch includes ₹1.2 lakhs in long-term capital gains (equity held >1 year). Since LTCG up to ₹1.25 lakhs is exempt, the entire gain is tax-free this time. The switch is executed with zero tax impact. Post-rebalancing: Equity: ₹20.9 lakhs (55%), Debt: ₹14.4 lakhs (38%), Liquid/Gold: ₹2.7 lakhs (7%). Back on target. Six months later, equity markets correct 18%. Sanjay's portfolio drops to ₹34 lakhs. New actual allocation: Equity: ₹16.3 lakhs (48%), Debt: ₹14.9 lakhs (44%), Liquid/Gold: ₹2.8 lakhs (8%). Equity has drifted 7% below target — a threshold breach. Rebalancing Action: Target equity: 55% of ₹34 lakhs = ₹18.7 lakhs Switch ₹2.4 lakhs from debt to equity — effectively buying equity at 18% lower prices. Result: Because of the April rebalancing, ₹3.8 lakhs was moved out of equity before the correction (selling high). Now ₹2.4 lakhs is being put back in at lower prices (buying low). Over the full cycle, this disciplined rebalancing adds meaningful alpha compared to a portfolio that was left untouched.

3 questions to check your understanding
A portfolio with target allocation of 60% equity and 40% debt currently has 72% equity and 28% debt after a market rally. Using threshold-based rebalancing with a 5% threshold, what action should be taken?
Summary Notes
Rebalancing enforces the buy-low-sell-high discipline systematically — selling overweight asset classes after rallies and buying underweight ones after corrections
Two approaches: calendar-based (annual, on a fixed date) and threshold-based (when drift exceeds 5-10%); combining both — quarterly monitoring with annual comprehensive review — is optimal
Every switch triggers capital gains tax — use the ₹1.25 lakh annual LTCG exemption strategically and consider cash flow rebalancing (redirecting new SIPs) for tax efficiency
Do not rebalance when drift is under 5%, when the client is near-goal (de-risk instead), or in a single large bet during a crash (use tranches over 2-3 months)
Annual review is the cornerstone of active client management: allocation check, performance review, SIP step-up, insurance review, goal progress tracking, and documentation

Frequently asked questions
What if a client insists on aggressive allocation despite having low risk capacity?
This is one of the most common situations distributors face. The conversation must be documented thoroughly. The client should be informed, preferably in writing, that their financial situation suggests a conservative approach. If they still insist, there are two options: (1) allocate a small "satellite" portion (10-15%) to aggressive funds while keeping the core conservative, giving them the thrill without jeopardizing the portfolio, or (2) decline the mandate if the mismatch is too severe. Suitability should never be compromised to retain a client — it will backfire when markets correct. SEBI holds distributors accountable for suitability.
How often should risk profiling be redone?
At minimum, conduct a formal risk profiling review every 2-3 years. However, trigger an immediate reassessment whenever there is a major life event: marriage, birth of a child, job change, significant salary hike, inheritance, retirement, medical emergency, or divorce. Also review if the client's investment behaviour during a market correction contradicts their stated risk profile — if they panicked and redeemed during a 15% correction despite claiming aggressive tolerance, their real tolerance is lower.
Is there a standard risk profiling questionnaire prescribed by SEBI?
SEBI does not prescribe a specific questionnaire but mandates that distributors assess suitability before recommending products. AMFI provides a model risk profiling framework. Most large AMCs — HDFC, ICICI Prudential, SBI — have their own proprietary questionnaires. Distributors can use any standardized questionnaire that covers income, goals, time horizon, investment experience, reaction to losses, and overall financial situation. The key is that the process is documented and consistent.
Can two people with the same income have completely different risk profiles?
Absolutely — this is exactly why risk profiling exists. Consider two people earning ₹15 lakhs/year: Person A is 28, single, no loans, lives with parents, has ₹5 lakhs emergency fund and government health insurance through employer. Person B is 45, sole earner with two dependents, ₹40 lakh home loan, no emergency fund. Person A can be Aggressive or Very Aggressive. Person B should be Conservative to Moderate at best. Income alone reveals almost nothing about the right allocation.
What is the difference between KYC compliance and risk profiling?
KYC compliance is a regulatory requirement focused on identity verification — PAN, Aadhaar, address proof, photograph, and in-person verification or video KYC. It is administered by KRAs (KYC Registration Agencies) like CAMS KRA and KFintech KRA. Risk profiling is a separate advisory function focused on assessing investment suitability. A client can be KYC-compliant but not yet risk-profiled. Both are necessary before recommending any mutual fund scheme — KYC is the legal gate, risk profiling is the advisory gate.
Should small cap funds be recommended to a 50-year-old investor?
Generally no, not as a core allocation. Small cap funds can have drawdowns of 40-60% during bear markets, and a 50-year-old approaching retirement cannot afford to wait 5-7 years for recovery. However, if the client has a very large portfolio, a small 5-10% tactical allocation in small cap may be acceptable as a satellite holding, provided the core portfolio is conservative. Always base the recommendation on the risk profile, not just a single factor.
How should a distributor handle a young client who says they have very low risk tolerance?
The approach should start with education — showing historical data on how equity markets have always recovered and grown over 10-15 year periods. Beginning with a balanced advantage fund or conservative hybrid fund rather than pure equity is advisable. As clients see steady returns and gain confidence, the distributor can gradually suggest shifting a portion to flexi cap or large cap equity over 12-18 months. Sometimes low risk tolerance is simply fear of the unknown, and experience is the best educator. Aggressive allocation should never be forced on an uncomfortable client.
Why is SWP better than the dividend (IDCW) option for regular income?
Three reasons: (1) Tax efficiency — SWP from equity funds held over 1 year attracts LTCG tax at 12.5% (with ₹1.25 lakh exemption), while IDCW is taxed at the investor's full income tax slab rate (up to 30%+). (2) Predictability — SWP gives a fixed amount on a fixed date, while IDCW amounts vary and are not guaranteed. (3) Capital efficiency — SWP redeems units systematically from a growing corpus, while IDCW reduces the NAV by the payout amount. For retirees needing regular income, SWP from a balanced advantage fund is almost always the superior choice.
