Topic of the Month – October 2027: How to Plan the Final Quarter of Your Investment Year
Key takeaways
- October is a natural moment to pause, check your allocation, and draft a plan through year-end.
- Q4 rebalancing can be combined with tax optimisation — selling losing positions reduces your taxable income.
- Set a specific date and checklist — without structure, the Q4 review gets pushed to the Christmas rush.
- Check whether your annual contributions (pension, DIP, building savings) are meeting the limits for a tax deduction.
- Formulate new investment goals for next year now, not on December 31st.
October is the natural start of the final quarter — and for investors one of the most important moments of the year to pause and check where the portfolio and the plan stand. Those who put it off until December make decisions under time pressure and tax stress.
Why a Q4 Review Matters
Three months remain until year-end — enough time for rebalancing, yet close enough for actions to be meaningful. Markets are historically more volatile in October, which paradoxically creates opportunities to buy on dips. And the tax year has a hard deadline: what doesn't happen by December 31st will wait a full year.
Four Points of the October Checklist
- Allocation: Does your current split of equities, bonds, and cash match your original plan? A strong year can overweight one component and push risk above your comfort level.
- Tax optimisation: Do you hold positions at a loss that you don't plan to keep anyway? Selling and buying back (watch out for wash-sale rules) can reduce taxable gains. In the Czech Republic general income tax rules apply — consult a tax advisor for specifics.
- Contribution limits: Make sure you've topped up tax-deductible products (DIP, pension savings) up to the statutory limits for the year.
- Goals for next year: Formulate them now — your target monthly investment amount, any new positions, and any planned allocation changes.
Connecting This to Rebalancing
Rebalancing doesn't have to be expensive or complex — just direct new contributions to the underweighted component. Only if the deviation is large should you sell and buy. The full logic is described in how to build your first portfolio. And if you're figuring out how ETFs work in a tax context, read ETF taxation in the Czech Republic.

FAQ
What is rebalancing and why do it at year-end?
Rebalancing is restoring your portfolio to its target component weights. At year-end it makes sense to combine it with tax optimisation — sell losing positions, use deductible contribution limits, and set a plan for the new year.
How does tax optimisation for investments work in the Czech Republic?
In the Czech Republic general personal income tax rules apply. Losses from selling securities reduce your taxable income in the same tax year. The exact approach depends on your circumstances — we recommend consulting a tax advisor.
What is DIP and why top it up before year-end?
DIP (Dlouhodobý investiční produkt — Long-Term Investment Product) is a Czech tax-advantaged product allowing you to deduct contributions from your taxable income up to the statutory limit. Contributions cannot be carried over to the next year — anything not made by December 31st is lost as a deductible item.
