GSR has shifted its Core3 model portfolio, cutting Bitcoin to its lowest allocation of the three assets and making Solana the largest position. In the latest weekly rebalance, Solana's weighting rose to 43.6%, while Ether was set at 39.5% and Bitcoin fell to 16.9%. The move flips the prior setup from Aug. 5, when Ether held the top spot.
Why Solana jumped
The Core3 model is a weekly rebalanced signal portfolio that doesn't hold client funds. It favors recent relative strength over trailing performance, and the numbers reflect that. Over the past week, Solana gained 2.98%, while Bitcoin fell 1.02% and Ether slipped 0.20%.
That short-term edge was enough to push Solana past Ether, even though the asset's longer-term picture is rough. Solana is down 36.69% year-to-date and 60.80% over the past year.
Volatility gap
The three assets are trading in very different regimes. Bitcoin sits near $63,513 with a 30-day volatility of 26.82%, the lowest of the group. Solana trades near $76 with a 60-day volatility of 48.84%, the highest. Ether's allocation sits in the middle, both in weighting and in the risk profile implied by the model's inputs.
That volatility spread is part of why the model keeps rotating. It's not a bet on Solana's fundamentals — it's a signal-driven response to which asset has been moving hardest in the short run.
How the model has performed
The strategy's track record is mixed. Core3 lost 70.28% over the past year versus a 63.44% loss for an equal-weight basket of the same three assets. Year-to-date, it's down 35.58% compared to a 32.22% decline for that benchmark.
In other words, the model has underperformed a simple equal-weight split over both periods. The rebalance logic is chasing relative strength, and that hasn't paid off recently. The timing of this week's shift — cutting Bitcoin to its smallest share just as its volatility cools — is notable, but the model doesn't make calls based on where volatility might go next. It reacts to what's already happened.
The next weekly rebalance is due in about seven days, and that will be the first test of whether this Solana-heavy weighting holds or gets unwound just as quickly.
