계산기

()을 포트폴리오 계산기에 추가해 현재 비중과 목표 비중 차이를 점검할 수 있습니다.

비중을 볼 때 확인할 점

  • 현재 보유 수량과 현금 기준 평가금액을 먼저 확인합니다.
  • 목표 비중과 실제 비중 차이가 큰지 확인합니다.

리밸런싱 전 리스크

  • 단일 종목 비중이 커지면 포트폴리오 변동성이 커질 수 있습니다.
  • 실제 주문 전 가격, 환율, 수수료를 다시 확인합니다.

계산기에서 확인하는 순서

  1. 1.를 포트폴리오에 추가합니다.
  2. 2.보유 수량, 현금, 목표 비중을 입력합니다.
  3. 3.목표보다 과대·과소 편입인지 보고 매수·매도 필요 수량을 확인합니다.

비중 계산 기준

리밸런싱 계산기는 의 현재 평가금액, 포트폴리오 현금, 다른 보유 종목의 평가금액을 함께 놓고 목표 비중과의 차이를 계산합니다. 실제 주문 수량은 현재가, 환율, 거래 수수료, 최소 주문 단위에 따라 달라질 수 있으므로 결과를 주문 전 점검용으로 사용하세요.

신규 매수 전 목표 비중을 정하거나, 비중이 커진 뒤 일부를 줄일지 확인할 때 유용합니다. 여러 종목을 함께 보유한다면 단일 수익률보다 전체 포트폴리오에서 차지하는 비중과 변동성 기여도를 먼저 확인하는 편이 안전합니다.

Rebalancing Meaning: What is Portfolio Rebalancing?

Learn what rebalancing means, why it matters, and how to do it — all in one guide.

Quick Definition

Rebalancing is the process of restoring your portfolio's asset allocations back to their target weights when market movements cause them to drift — by selling overweight assets and buying underweight ones.

What is Rebalancing?

Portfolio rebalancing is the process of realigning asset weights that have drifted from target allocations. For example, if a 60/40 stock-bond portfolio has shifted to 70/30 due to stock gains, you would sell some stocks and buy bonds to restore the original ratio.

As markets move, your asset allocations naturally shift. Without rebalancing, your portfolio can become overly concentrated in certain assets, taking on unintended risk. Regular rebalancing is the key strategy to address this.

5 Reasons Why Rebalancing Matters

1

Risk Management

When allocations drift from targets, your portfolio's risk level changes too. Rebalancing maintains your intended risk profile.

2

Prevent Emotional Trading

Rule-based buying and selling prevents fear and greed-driven decisions during market volatility.

3

Sell High, Buy Low Effect

Reducing outperformers and adding to underperformers naturally creates a "sell high, buy low" discipline.

4

Stabilize Long-term Returns

Preventing concentration reduces volatility and maximizes the compounding effect over time.

5

Maintain Investment Discipline

Consistently maintaining your original strategy and allocation helps achieve long-term investment goals.

Rebalancing Methods: Calendar vs Band

Calendar Rebalancing

Executed at fixed intervals (monthly, quarterly, or annually). Simple and easy to maintain discipline.

Pros: Simple, minimizes emotional interference

Cons: May trigger unnecessary trades

Band Rebalancing

Triggered only when allocations drift beyond ±5-10% from target. Reduces unnecessary trades while maintaining balance.

Pros: Saves transaction costs, efficient

Cons: Requires monitoring

Hybrid Approach (Recommended)

Combining quarterly reviews with band conditions improves trading efficiency. This is the method most experts recommend.

Sequence

  • Review the individual portfolio flow even when no portfolio exists or data is still loading.
  • Use the highlighted mobile controls in the order shown on the image.
  • Confirm the selected portfolio or group before moving to the next step.

What to verify

  • This step affects later rebalance calculations.
  • Review names, weights, quantities, and cash before continuing.
  • If something looks wrong, return to the previous input and correct it.

Watch out

  • The calculator does not place brokerage orders.
  • Verify brokerage prices, executable quantities, taxes, and cash before real trades.

Setting Your Rebalancing Frequency

The right frequency varies by individual, but quarterly to annual rebalancing is most common.

  • For more volatile assets, set wider bands (e.g., ±10%)
  • Avoid small, frequent trades; prefer adjusting with new cash inflows
  • In taxable accounts, minimizing taxable events is essential
  • Use tax-advantaged accounts (IRA, 401k) to rebalance with less tax burden

Tax and Cost Considerations

When rebalancing, consider total transaction costs including fees, spreads, and taxes. Set thresholds to reduce excessive trading, and in taxable accounts, consider tax-loss harvesting and holding period taxation.

  • Taxable accounts: Sales may trigger capital gains tax → reduce frequency or use cash inflows instead
  • Tax-advantaged accounts (IRA/401k): Rebalance freely without tax concerns
  • Fees/spreads: Higher trading frequency means higher costs → use band method to minimize unnecessary trades

Real Example: Before/After

Let's look at a 60/40 portfolio (60% stocks, 40% bonds) after market movements caused the allocation to drift.

AssetTargetAfter DriftActionAfter Rebalance
US Stocks (VTI)60%68%Sell 8%p60%
US Bonds (AGG)40%32%Buy 8%p40%

When the allocation drifted by 8%p from target, selling the overweight stocks and buying underweight bonds restores the original target. This is the essence of rebalancing.

Frequently Asked Questions

What does rebalancing mean exactly?

Rebalancing means restoring your portfolio's asset weights back to the original target allocation when they have drifted due to market movements.

When should I start rebalancing?

It is best to start consistently right after setting your target allocations.

Can I rebalance using only new cash?

Yes. It is a great way to reduce taxes and fees.

Does rebalancing always improve returns?

Not always. However, it helps with volatility management and risk control.

How do I set the band threshold?

For more volatile assets, set wider bands (e.g., ±10%), and combining with quarterly reviews can reduce excessive trading.

What's the Korean misspelling issue with rebalancing?

In Korean, 'rebalancing' is written as '리밸런싱'. It is sometimes misspelled as '리벨런싱', but both refer to restoring your portfolio's target asset allocation.

How do I use a rebalancing calculator?

Enter your holdings and current amounts into the rebalancing calculator, and it will automatically calculate how much to buy and sell to reach your target allocation.

Do ETF portfolios need rebalancing too?

Yes, ETF allocations drift with market movements just like individual stocks, so regular rebalancing is necessary.
