    Keeping It Alive: Rebalancing, Review, and Your Written Thesis

    18 min readUpdated

    Understand two rebalancing methods and when (and when not) to use each.

    When to Rebalance: Rules That Remove Emotion

    You built a portfolio. 40% BTC, 25% ETH, 10% stablecoins, 25% in satellites. Three months later, one satellite pumped 300% and now represents 40% of your portfolio. BTC drifted down to 28%. Your careful structure is gone.

    This is portfolio drift, and it happens to everyone. The question is: do you fix it? And when?

    Why Rebalancing Matters

    Rebalancing means selling what went up and buying what went down to return to your target allocation. It sounds counterintuitive. Why sell your winners?

    Because your winners becoming a huge portion of your portfolio means your risk profile has changed without you deciding to change it. That satellite that pumped 300% is now your largest position. If it crashes 70% (which speculative tokens do), it takes your entire portfolio down with it.

    Rebalancing is not about giving up gains. It's about maintaining the risk level you chose when you were thinking clearly.

    Without rebalancing, a BTC bull run silently pushes its weight from 50% to 70% of the portfolio, increasing single-asset exposure and depleting the cash buffer needed for drawdowns and dip buying.

    Two Rebalancing Approaches

    Calendar Rebalancing. You rebalance on a fixed schedule, regardless of what happened. Monthly or quarterly is common.

    Pros: Simple, removes emotion, easy to follow Cons: You might rebalance when nothing has drifted significantly (wasting fees) or ignore a massive drift between scheduled dates

    Threshold Rebalancing. You rebalance when any position drifts more than a set percentage from its target. Common thresholds: 5% or 10% absolute drift.

    Example: Your target for BTC is 40%. You set a 5% threshold. If BTC drifts to 45% or below 35%, you rebalance. Otherwise, you leave it alone.

    Pros: Only rebalances when it matters, saves on fees and tax events Cons: Requires monitoring, which can lead to checking too often

    The Hybrid (recommended): Check monthly. Only rebalance if any position has drifted more than 5% from target. This gives you the structure of calendar rebalancing with the efficiency of threshold rebalancing.

    Two Rebalancing Methods: Choose Based on DisciplineTHRESHOLD METHODTriggerAny asset drifts ±10% from targetProsOnly rebalances when truly neededMinimises unnecessary tax eventsConsRequires active price monitoringMay miss drift in slow marketsCALENDAR METHODTriggerFixed schedule, every 3 monthsProsSimple, set calendar reminderConsistent discipline, no guessworkConsMay rebalance unnecessarilyCould cut winners too earlyIndia context: every rebalance is a taxable sell event. Choose the method that minimises unnecessary transactions
    The threshold method reacts to actual drift and creates fewer tax events, while the calendar method is easier to maintain consistently. In the Indian tax context, either approach beats never rebalancing at all.

    The Tax Cost of Rebalancing in India

    Every rebalance involves selling some crypto. Any gain on what you sell is taxed at 30%, and 1% TDS is withheld from the sale value (it comes back as a credit when you file). The tax is real money. Rebalancing too frequently eats into your returns.

    Practical rules for Indian investors:

    • Rebalance no more than once per quarter
    • Only rebalance positions with drift above 5%
    • When possible, rebalance by adding new money to underweight positions rather than selling overweight positions (this avoids triggering tax events)
    • Keep records of every rebalance for your tax documentation

    Kavita's Rebalancing Decision

    Kavita's satellite position in an AI token went from 8% to 22% of her portfolio in two months. She loved the project and didn't want to sell. But she remembered her framework: no single satellite above 10%.

    She sold half the position (bringing it to ~11%) and moved the proceeds into her stablecoin reserve and an underweight BTC position. Two weeks later, the AI token corrected 45%. Her portfolio barely felt it because she'd already locked in gains and reduced concentration.

    If she'd held, that 45% crash on a 22% position would have cost her 10% of her total portfolio. Instead, she lost about 5% on the remaining 11%. Rebalancing didn't feel good in the moment. It felt great two weeks later.

    Quick Recap

    • Portfolio drift happens naturally as prices move, and it changes your risk without your permission
    • Rebalancing restores your target allocation by selling winners and buying laggards
    • Calendar (fixed schedule) vs threshold (drift triggers): use a hybrid of both
    • In India, a sale at a gain is taxed at 30% and has 1% TDS withheld, so rebalance infrequently
    • Prefer adding new money to underweight positions over selling overweight ones
    • No position should drift more than 5% from target before you act

    Checklist

    • Write down your target allocation with specific percentages
    • Choose your rebalancing approach: calendar, threshold, or hybrid
    • Set your drift threshold (5% recommended for beginners)
    • Schedule a monthly portfolio check-in on your calendar
    • Record every rebalance for tax documentation

    Common Mistakes

    • Never rebalancing, and letting winners grow until they dominate the portfolio
    • Rebalancing too frequently, racking up tax events and fees
    • Emotional rebalancing, selling a loser because you're frustrated, not because it drifted
    • Not accounting for tax costs when rebalancing, because the 30% tax can make small rebalances net negative

    Key takeaways

    What to remember

    1. Threshold rebalancing: triggered by drift; Calendar rebalancing: triggered by schedule
    2. Never rebalance during strong trend continuation, because selling winners too early destroys returns
    3. Calculate tax cost before every rebalance, because 30% on gains may exceed the benefit for small drifts
    4. Rebalancing forces contrarian behavior: buy weakness, sell strength systematically
