Solana has historically acted as a better portfolio diversifier than ether alongside bitcoin, according to Morgan Stanley analysis, despite being more volatile.
Denny Galindo, Executive Director of Morgan Stanley Wealth Management’s Global Investment Office, compared correlation coefficients and volatility metrics across bitcoin, ether, and SOL to evaluate their diversification characteristics. “Historically, SOL has acted as a better diversifier than ether,” Galindo said in analysis published by CoinDesk.
Over a four-year period through April 2026, bitcoin and ether maintained a 0.78 correlation coefficient, while bitcoin and SOL showed a lower 0.72 correlation. Lower correlation typically signals stronger diversification potential in a portfolio.
Both ether and SOL have grown more volatile relative to bitcoin since the start of 2026. Ether volatility increased 35% versus bitcoin, while SOL volatility climbed 44%. Despite this elevated volatility, SOL’s lower correlation with bitcoin suggests it may offer portfolio benefits that ether does not.
SOL also demonstrated a slightly lower correlation with the S&P 500 Index than both bitcoin and ether, according to the analysis.
The comparison follows $55 billion in inflows to bitcoin spot exchange-traded products since their January 2024 launch, a milestone that enabled subsequent ether and SOL ETP launches. Bitcoin has maintained relatively low correlations with traditional asset classes over full four-year crypto cycles.
Galindo cautioned against treating historical patterns as predictive. “Historical relationships may not persist, and past diversification characteristics should not be viewed as indicators of future results,” he said.
Galindo identified three investor motivations driving crypto allocation decisions: digital gold preference centered on bitcoin, blockchain adoption and disruption focus spanning bitcoin, ether, and SOL, and diversification seeking that favors either bitcoin alone or bitcoin paired with SOL.
