The move represents a sharp reversal from the prior week. On Aug. 5, Solana held 36.5%, Ether 44.1%, and Bitcoin 19.3%. Within seven days, Solana gained 7.1 percentage points, while Ether lost 4.6 points and Bitcoin dropped 2.4 points.
GSR said the change was driven by its proprietary relative alpha signals, which pointed toward stronger near-term price momentum in Solana. The firm was clear that Core3 is a model framework for professional investors and is not a live investment recommendation.
Solana posted the best seven-day return in the table at 2.98%. Bitcoin fell 1.02% over the same period, and Ether slipped 0.20%.
Over 30 days, however, Ether led with a 7.88% gain. Bitcoin returned 3.19% and Solana 2.44% over that window.
Core3 Model Performance
The Core3 portfolio returned 0.85% over one week and 5.30% over one month. Both figures beat the equal weight basket, which returned 0.59% and 4.68% respectively.
Over longer periods, Core3 remains underwater. It is down 35.58% year to date and 70.28% over one year. The equal weight basket is down 32.22% and 63.44% over those same periods.
Thirty-day volatility sits at 26.82% for Bitcoin, 39.75% for Ether, and 35.26% for Solana. GSR noted that Solana’s trading volume had softened over both seven and 30-day windows, meaning the larger weight did not come with stronger volume.
U.S. Solana Products Expand
The model shift comes as U.S. investors gain more regulated access to Solana. Morgan Stanley launched the Morgan Stanley Solana Trust (MSOL) on NYSE Arca on July 28, carrying a 0.14% expense ratio. The product can stake up to 100% of its SOL holdings under normal conditions.
21Shares also filed on July 27 to waive the 0.21% sponsor fee on its TSOL product for one year starting July 28.
Analyst Michaël van de Poppe (@CryptoMichNL) weighed in on SOL’s price structure, saying he wants to see Solana continue printing higher lows. He noted that the $73.50–$74 area is a key support level to hold. If that support holds, he sees targets toward $120 remaining intact.
Quite clearly you'd want to see $SOL continue to be printing higher lows.
In that regard, I think it's important to hold the $73.5-74 area for support.
If that happens, the targets to $120 remain intact. pic.twitter.com/yKALiRlAHF
