Why Selling Your Best-Performing Crypto Position Is Sometimes the Right Move

The Convictions portfolio just trimmed its Hyperliquid position for the second time in two weeks, even though HYPE has returned over 55% since we first bought it. If that sounds wrong to you, you are not alone. Every instinct says: why would you sell something that has done so well?

The Convictions portfolio just trimmed its Hyperliquid position for the second time in two weeks, even though HYPE has returned over 55% since we first bought it. If that sounds wrong to you, you are not alone. Every instinct says: why would you sell something that has done so well?

The answer comes from a foundational idea in portfolio management called fixed-weight rebalancing. The portfolio was designed with specific target allocations: 30% in Bitcoin, 30% in Hyperliquid, 30% in the CMC20 index (an equal-weighted basket of the top 20 cryptocurrencies by market value), and 10% in Pendle Finance. These weights were not chosen casually. They represent a considered judgment about how much risk the portfolio should take on each bet, how much any single asset can move without destabilizing everything else, and how to balance conviction with humility. A 30% position says: we believe in this, but not unconditionally.

When HYPE rises 55% while Bitcoin falls 8%, something mechanical happens. The portfolio that started with four balanced pieces now looks very different. By today, HYPE had grown to almost 42% of the total portfolio. Bitcoin had shrunk to about 25%. Pendle had dropped to under 8%. The portfolio was no longer expressing the original view. It was now expressing a single view: Hyperliquid goes up. That is not what the portfolio was built to say.

Rebalancing is the tool that restores the original view. By trimming HYPE and buying more of the tokens that have fallen behind, the portfolio forces a systematic version of buying low and selling high, without requiring any judgment about where prices will go next. The discipline does not depend on believing HYPE will fall. It does not require pessimism. It only requires the conviction that the original allocation was correctly sized and should be maintained. The historical evidence supports this: fixed-weight portfolios rebalanced quarterly tend to outperform drift portfolios over multi-year horizons, because they mechanically harvest volatility into returns.

There is a second reason that matters here specifically. Cryptocurrency is one of the most volatile asset classes in existence. A single position doubling or halving in a month is not unusual. If a fixed-weight portfolio does not rebalance aggressively, one token can eat the entire portfolio in a bull run, concentrating risk precisely when it is highest. Convictions experienced this with HYPE. The token rose fast enough to reach 41.9% of the portfolio, the second time in less than a week that it crossed the 10 percentage point drift threshold that triggers an immediate rebalance.

The practical implication for anyone building a similar strategy: the rebalance threshold matters as much as the target weights. A 5 percentage point soft trigger (for scheduled Mondays) combined with a 10 percentage point hard trigger (immediate action, any day) creates a system that lets winners run while still capping concentration risk. Without the hard trigger, a fast-moving asset can blow past your intended limit before the next scheduled check arrives.

The Convictions portfolio holds HYPE because the thesis is sound: Hyperliquid has built a decentralized order book for perpetual futures (financial contracts that let people bet on price direction without expiry dates) that is competing directly with centralized exchanges. The daily trading volume is growing, and this week the protocol launched prediction markets governed by its own validators, another product that adds utility to the ecosystem. None of that has changed. We are not selling because the thesis broke. We are selling because the position grew too large to safely express the thesis.

That distinction is worth holding onto. Rebalancing is not an exit. It is a recalibration. The portfolio still believes in HYPE. It just believes in it at 30%, not 42%.
