1. Rebalancing என்னன்னு?

Target allocation-ல இருந்து drift ஆன portfolio-ஐ back to original ratio-க்கு adjust பண்றது.

⚖️ Simple Example

Target: 70% Equity + 30% Debt → Bull run 2 years → 83% Equity + 17% Debt.
Rebalance → Back to 70% Equity + 30% Debt. Risk controlled!

2. Why Rebalancing is Critical

⚠️ Without Rebalancing

70% equity → grows to 83% → next crash: -35% loss instead of planned -25%!
10% extra loss = massive wealth impact over time.

✅ With Annual Rebalancing

Portfolio stays near target. Crash impact controlled. Recovery faster. Wealth protected!

3. 5% Drift Rule

Equity70%76%+6%TRIGGER! Sell equity

Mid Cap20%23%+3%No action ✓

4. Annual Calendar — March 31 = Rebalance Day

📅 Why March 31?

Financial year end. LTCG ₹1.25L harvest opportunity. Fresh FY start. Tax planning aligned. Best time for India investors!

  • Jan-Feb: Track only, no action
  • March 31: 🎯 REBALANCE DAY — full reset
  • April: SIP step-up (salary hike)
  • Oct-Nov: Mid-year check if major event

5. 3 Rebalancing Methods

💰 Method 1: Sell + Buy

Overweight fund sell → Underweight buy. Classic, direct, immediate.

⚠️ Tax event — plan ₹1.25L

🔄 Method 2: SIP Redirect

SIP amount change only. No selling. Gradual rebalance.

✓ No tax event — best for most!

💵 Method 3: New Lumpsum

Bonus → underweight asset directly. No selling, no tax.

✓ Best when bonus received

6. Tax-Efficient Rebalancing

  • LTCG ₹1.25L Harvest: Every March — sell ₹1.25L profit → zero tax → reinvest same day
  • SIP Redirect: No selling = no tax event. Slower but cleanest
  • Tax Loss Harvesting: Losing position sell → offset STCG gains
💡 Pro Tip

SIP redirect method = zero tax rebalancing. Simply change SIP amount per fund. Over 3-6 months, portfolio naturally rebalances. Best for regular investors!

7. Bull Market Rebalancing

Hardest discipline — sell equity when it's going up! But essential.

⚖️ Why You Must

83% equity at bull peak → next crash = 35% loss vs 25% planned. Rebalancing = automatic sell high. Set March 31 date. Follow process regardless of market direction!

8. Bear Market Rebalancing

Even harder — buy equity when panic everywhere! But highest returning action.

💎 Opportunity

Equity falls to 55%, target 70% → buy cheap equity from debt proceeds! March 2020 rebalancers bought at bottom → 4x return by Dec 2021!

10. Common Mistakes

  • 🚫 Tax ignore → SIP redirect prefer, ₹1.25L window use
  • 🚫 Monthly/weekly rebalance → Annual only!
  • 🚫 Full fund exit → Partial only for rebalancing
  • 🚫 Ignore goal timeline → Goal-based adjustment needed
