A Morgan Stanley report argues that Solana (SOL) may offer better diversification benefits than Ethereum (ETH) when added to a Bitcoin (BTC) portfolio. The analysis, published by Denny Galindo of the firm's Global Investment Office, focuses on correlation and dispersion effects as key criteria for including crypto assets.
Correlation and Volatility
Bitcoin has historically shown low correlation with traditional assets, earning it the 'digital gold' label. However, adding Ethereum and Solana complicates the picture. Both assets are less liquid and more volatile than Bitcoin — in 2026, Ethereum and Solana have exhibited roughly 35% and 44% higher volatility relative to Bitcoin, respectively.
The crucial factor is how they move. The correlation coefficient between Bitcoin and Ethereum stands at 0.78, while for Solana it is lower at 0.72. This suggests Solana is more likely to move independently of Bitcoin during market swings. Moreover, Solana's correlation with the S&P 500 is also lower than that of Bitcoin or Ethereum, making it a stronger non-correlated asset within a traditional portfolio.
Strategy Depends on Investor Goals
The report notes that investment strategy should align with the investor's objective. Those viewing Bitcoin as digital gold will likely stick with a Bitcoin-centric approach. Investors betting on blockchain adoption and financial innovation may opt for a mix of Bitcoin, Ethereum and Solana. For pure diversification, a combination of Bitcoin and Solana is presented as an alternative. However, Galindo cautions that past correlations are not guaranteed to persist, and he stops short of explicitly recommending any specific asset.
Institutional Adoption Accelerates
Meanwhile, the crypto market is seeing increased institutional integration. Stablecoin issuer Circle obtained a federal trust bank charter from the OCC, and SWIFT has begun blockchain-based payment tests with 17 banks including Citi, HSBC and UBS. The SEC is also preparing rules to ease token issuance and fundraising, potentially boosting on-chain finance participation. Separately, Strategy sold approximately 3,588 Bitcoin worth about $216 million, signaling a shift from pure HODLing to using Bitcoin for liquidity management.
Robinhood Chain Sees Uniswap Dominance
The Layer-2 network Robinhood Chain has recorded average daily DEX volume of around $690 million since its July 1 mainnet launch, with 99.5% of that activity concentrated on Uniswap. The extreme protocol concentration highlights ongoing centralization within decentralized finance.
