July marks the halfway point of the investment year, and for passive investors who hold ETF portfolios, it is the ideal moment for a systematic rebalance. With interest rates stabilising after two years of gradual cuts and equity markets adjusting to the AI productivity wave, the landscape in mid-2026 calls for deliberate allocation decisions.
Why July rebalancing matters
Most investors only rebalance annually, but mid-year corrections can drift a portfolio 5-10% from its target allocation — enough to meaningfully change your risk profile. Tech-heavy ETFs have outperformed broadly in the first half of 2026, meaning many portfolios are now overweight in equities and underweight in bonds or alternatives.
Sectors to watch
AI infrastructure and clean energy ETFs continue to show strong momentum, but valuations are stretched. Defensive sectors like healthcare and consumer staples offer better value. Consider small-cap ETFs as a hedge — they have historically outperformed large-caps in the second half of years following rate-cutting cycles.
A simple rebalancing rule
If any asset class is more than 5% above or below your target allocation, sell the excess and buy the underweight. Do this in a tax-advantaged account (IRA or 401k) to avoid capital gains taxes. For taxable accounts, direct new contributions to underweight positions instead of selling.
