How often should I rebalance my portfolio?

Most investors rebalance quarterly or annually, though some use a threshold-based approach — rebalancing whenever any asset drifts more than 5% from its target. The best approach depends on your strategy: calendar-based is simplest, threshold-based is more responsive, and dynamic rebalancing adapts your targets to market conditions.

Is JustRebalance free?

Yes! JustRebalance is completely free to use. Create an account, add your positions, set your target allocations, and calculate your rebalancing trades — all at no cost.

What are dynamic allocation scenarios?

Dynamic allocation scenarios let you define multiple target allocations (e.g., Defensive, Core, Aggressive) and switch between them based on your market outlook. Combined with fully custom asset classes — which you name, color-code, and organize yourself — this gives you total control over your portfolio structure.

What is the Invest Cash rebalancing mode?

Invest Cash is a buy-only rebalancing mode. Instead of selling overweight positions, it uses your available cash to purchase underweight positions proportionally. This is perfect when you receive new capital and want to deploy it without triggering sells on your winners.

Can I use JustRebalance with any portfolio?

JustRebalance works with any portfolio! You create your own custom asset classes — name them anything you want, assign colors, and organize them your way. Manage stocks, bonds, ETFs, commodities, crypto, and cash all in one place.

How to Rebalance Your Investment Portfolio: A Beginner's Guide

Q: What is portfolio rebalancing?

Portfolio rebalancing is the process of realigning your investment portfolio back to your target asset allocation. Over time, different assets grow at different rates, causing your portfolio to drift from its original targets. Rebalancing involves selling over-allocated assets and buying under-allocated ones to restore your intended balance.

What Is Portfolio Rebalancing?

Portfolio rebalancing is the process of realigning the weightings of the assets in your investment portfolio to match your original target allocation. Over time, as different investments grow at different rates, your portfolio naturally drifts away from the allocation you originally set. Rebalancing brings it back into line.

For example, if you started with 60% stocks and 40% bonds, a strong stock market rally might push your allocation to 75% stocks and 25% bonds. That's more risk than you intended. Rebalancing means selling some stocks and buying bonds to get back to 60/40.

Why Rebalancing Matters

Risk Management

Without rebalancing, your portfolio gradually becomes riskier or more conservative than you intended. What started as a balanced portfolio can drift into an aggressive one — or the opposite during a downturn.

Discipline Over Emotion

Rebalancing forces you to sell high and buy low systematically. When an asset class outperforms, you trim it. When one underperforms, you add to it. This is the opposite of what most emotional investors do.

Consistent Returns

Studies show that portfolios rebalanced regularly tend to achieve better risk-adjusted returns over the long term. It's not about maximizing returns — it's about maintaining the return profile you chose for your risk tolerance.

When Should You Rebalance?

There are three common approaches:

1. Calendar-Based Rebalancing

Set a schedule — quarterly, semi-annually, or annually — and rebalance on those dates regardless of what's happened in the market.

Pros: Simple, removes emotion from the decision.

Cons: May miss significant drift between rebalancing dates.

2. Threshold-Based Rebalancing

Rebalance whenever any asset class drifts more than a set percentage (commonly 5%) from its target.

Pros: More responsive to market movements.

Cons: Requires ongoing monitoring.

3. Dynamic Rebalancing

Adjust your target allocation based on market conditions or your investment thesis, then rebalance to the new targets. This is the approach used by cycle investors and tactical allocation strategies.

Pros: Adapts to changing market conditions.

Cons: Requires a disciplined system to avoid emotional decisions.

How to Rebalance: Step by Step

Step 1: Know Your Target Allocation

Before you can rebalance, you need a clear target. What percentage of your portfolio should be in stocks, bonds, commodities, cash, and other asset classes?

Step 2: Check Your Current Allocation

Look at your current portfolio and calculate the actual percentage each asset class represents. Compare this to your targets.

Step 3: Calculate the Trades

Determine which positions need to be increased and which need to be reduced. For each asset class, calculate the dollar amount needed to bring it back to target.

Step 4: Execute the Trades

Place the buy and sell orders. Many portfolio management tools — including JustRebalance — can calculate these trades for you automatically.

Step 5: Review and Repeat

Set a reminder for your next rebalancing check. Whether you use a calendar or threshold approach, consistency is key.

Common Mistakes to Avoid

Rebalancing too frequently — Transaction costs and taxes can eat into returns if you rebalance every time there's a small drift.

Ignoring tax implications — In taxable accounts, selling winners creates capital gains. Consider tax-loss harvesting or rebalancing with new contributions instead.

Emotional overrides — Sticking to your plan during market volatility is hard but essential. A tool that calculates the math for you removes the temptation to deviate.

Forgetting to update targets — Your life circumstances change. Revisit your target allocation annually.
