What Is Portfolio Rebalancing?

Rebalancing means bringing your portfolio back to your target mix. You sell some of what grew too much. You buy more of what lagged. This keeps your risk level where you want it.

Think of it like a seesaw. When one side gets too heavy, you add weight to the other side. Rebalancing does the same thing for your money.

Why Rebalancing Matters?

Without rebalancing, your portfolio drifts. It becomes riskier over time. Why? Because stocks usually grow faster than bonds. After a few good years, stocks take over your portfolio.

If a crash comes, you lose more than you planned. Rebalancing protects you from this. It forces you to sell high and buy low. It is mechanical. It removes emotions from your decisions.

Portfolio Rebalancing Example

Let me give you a simple example.

You have 10,00,000. Your target is 60% stocks and 40% bonds.

• Stocks: 6,00,000
• Bonds: 4,00,000

After one year, stocks grew 25%. Bonds grew 5%.

• Stocks: 7,50,000
• Bonds: 4,20,000
• Total: 11,70,000

Now your mix is 64% stocks and 36% bonds. You are taking more risk than planned.

To rebalance, you need 60% of 11,70,000 in stocks. That is 7,02,000. You sell 48,000 of stocks and buy 48,000 of bonds.

Now you are back to 60/40. You sold high and bought low. That is the power of rebalancing.

When to Rebalance?

There are two common methods.

• Calendar rebalancing: You check your portfolio on a fixed date. Once a year. Or every six months. If it has drifted, you rebalance.
• Threshold rebalancing: You set a limit. If any asset moves more than 5% from its target, you rebalance. This can happen anytime.

Most experts suggest a mix. Check every six months. Rebalance if the drift is more than 5%. This balances cost and control.

Portfolio Rebalancing Calculator

You can use online calculators to do the math for you. Here is what they ask for:

• Current portfolio value
• Current allocation of each asset
• Target allocation of each asset

The calculator tells you how much to buy or sell of each asset. Many free tools are available online. Your broker may also have one built into their app.

How to Rebalance Portfolio Without Selling?

Selling triggers taxes. It also creates costs. But you can rebalance without selling. Here is how.

Use New Contributions

Instead of selling stocks, direct your new SIP money into bonds. This slowly brings your mix back to target. It takes longer. But it avoids taxes and selling costs.

Example: If stocks are too high, put your next few SIPs into bonds. Do not sell stocks. Just buy more bonds. Over time, the mix balances out.

Use Dividends and Interest

If you receive dividends from stocks or interest from bonds, do not reinvest them in the same asset. Use that cash to buy the underweight asset.

Example: If stocks are too high, take the stock dividends and buy bonds. This rebalances without selling.

Rebalance Within Tax-Advantaged Accounts

If you have retirement accounts, rebalance there first. Selling inside these accounts does not trigger taxes. Keep your taxable accounts untouched.

Portfolio Rebalance Tool

Several tools can help you rebalance.

• Your broker's app: Most brokers have a rebalancing tool. It shows your current allocation and suggests trades.
• Spreadsheets: You can build a simple spreadsheet. List your assets. Enter current values. Enter target percentages. The sheet calculates what to buy or sell.
• Online calculators: Many free calculators do this. Just search "portfolio rebalancing calculator."
• Robo-advisors: Some robo-advisors rebalance automatically. They do it for you. You do not have to think about it.

How to Rebalance Stock Portfolio Without Paying Taxes?

Taxes are a big concern. Selling stocks held over 12 months triggers capital gains tax. In India, this is 12.5% above 1.25 lakh per year. Selling within 12 months triggers 20% tax.

Here is how to avoid taxes.

• Use new money. Direct new investments to the underweight asset. Do not sell anything.
• Use dividends. Take dividends in cash. Use them to buy the underweight asset.
• Rebalance in retirement accounts. Sell and buy inside these accounts. No taxes.
• Harvest losses. If you have losing positions, sell them. Use the losses to offset gains. Then rebalance with the proceeds.
• Be patient. If the drift is small, wait. Use new contributions to fix it over time. Do not sell just to rebalance.
