Portfolio Rebalancer

Most investors benefit from quarterly or semi-annual rebalancing, or threshold-based rebalancing with 5% tolerance bands. Annual rebalancing is minimum recommended. More frequent (monthly) is rarely necessary and increases costs. Choose a method and apply it consistently.

Yes - in fact, rebalancing during crashes is when it adds most value. Selling bonds (which held up) to buy equities (which fell) implements buy-low discipline. It feels uncomfortable but historically improves long-term returns. Stick to your rebalancing rules regardless of market conditions.

You need to sell overweight assets to fund purchases of underweight assets. Rebalancing is a simultaneous sell/buy process that should be cash-neutral (proceeds from sales fund purchases). Alternatively, direct new contributions to underweight assets over time.

Most super funds offer automatic rebalancing - check your fund's features. If you have a self-managed super fund (SMSF) or control your super investments, you should implement rebalancing just like a regular portfolio. Super's tax advantages make rebalancing less costly.

Australian shares often pay franked dividends. If rebalancing means selling Australian equities, you may reduce future franking credit income. Consider this in your overall tax planning. Using dividends from Australian shares to buy international assets naturally rebalances while keeping franking benefits.

Start with asset class rebalancing (equities/bonds/alternatives). Within asset classes, rebalancing individual stocks is optional but can manage concentration risk. If one stock has grown to dominate your equity allocation, consider trimming. For simplicity, many investors use ETFs and only rebalance at the ETF level.

For small portfolios or small drifts, transaction costs may exceed rebalancing benefit. Set minimum trade sizes (e.g., A$500) - do not rebalance positions requiring smaller trades. Use brokers with low fees. Cash-flow rebalancing (using contributions/dividends) avoids trading costs entirely.

International ETFs like VGS are unhedged, meaning you have currency exposure. Rebalancing between Australian (VAS) and international (VGS) also adjusts currency exposure. If you want to manage currency separately, consider hedged versions (VGAD) or factor currency into your allocation targets.

Monitor A-VIX or calculate realized volatility. Set rules: when A-VIX exceeds 25, tighten tolerance bands to 3% and consider reducing equity target by 10-20%. When A-VIX is below 15, widen bands to 7% and maintain or increase equity target. Backtest rules before implementing.

Yes - writing covered calls on overweight positions generates income and reduces effective exposure. Selling puts on underweight assets generates income and potentially acquires shares at lower prices. This options overlay can enhance rebalancing but requires options knowledge and is more complex.

First rebalance at the asset class level (equities/bonds). Then within equities, calculate factor exposures (P/E for value, momentum scores, quality metrics). If value factor has drifted, rebalance holdings to restore target value exposure. Factor analysis tools or factor ETFs simplify this process.

Research suggests threshold rebalancing with 5% bands slightly outperforms calendar rebalancing, primarily due to lower transaction costs and responsiveness to large drifts. However, the differences are small. Consistency matters more than the exact method. Tax efficiency in taxable accounts often dominates the choice.
