Asset allocation and Portfolio Rebalancing

Published · Updated

What Is Asset Allocation?

Asset allocation means dividing your investment money into different types of assets based on your goals and risk level.

The goal:

To balance risk and reward by spreading your money across different investments.

Common Asset Classes

Asset Type What It Is Risk Level
Stocks Ownership in companies High
Bonds Loans to companies or governments Low–Medium
Cash Savings or money market funds Very low
Real estate Property or REITs Medium
Crypto Digital assets like Bitcoin Very high

Example of Asset Allocation

Suppose you have $10,000 to invest. A common allocation for a balanced investor might look like:

  • 60% Stocks$6,000
  • 30% Bonds$3,000
  • 10% Cash$1,000

This mix depends on your age, goals, and risk tolerance.

What Is Portfolio Rebalancing?

Rebalancing means adjusting your investments back to your target allocation when market changes throw it off.

Over time, some assets grow faster than others, changing your mix — which might increase your risk without you realizing.

Example of Rebalancing:

Let's say your original plan was:

  • 60% Stocks
  • 30% Bonds
  • 10% Cash

But after 1 year, your stocks did very well and now your portfolio looks like:

  • 70% Stocks
  • 25% Bonds
  • 5% Cash

Rebalancing refers to adjusting a portfolio back to its original target allocation after market movements have shifted the weights — typically by trimming assets that have grown and adding to assets that have shrunk.


How Often to Rebalance?

  • Once or twice a year (e.g. every 6 or 12 months)
  • Or whenever your allocations shift too far from target (e.g. by 5% or more)

Characteristics of Asset Allocation & Rebalancing

Characteristic Mechanism
Concentration management Limits the portion of the portfolio exposed to a single asset class
Allocation stability Maintains target weights over multi-year horizons despite market movement
Mechanical contrarianism By restoring weights, trims outperforming assets and adds to underperforming ones
Time-horizon flexibility Target allocations can be updated as investor circumstances change
