Editorial illustration for: Morgan Stanley: Solana outperforms ether as crypto portfolio diversifier

In brief

  • Bitcoin spot ETPs attracted $55 billion in inflows since January 2024 launch
  • Solana's 0.72 bitcoin correlation vs ether's 0.78 over four years through April 2026
  • Solana shows lower S&P 500 correlation than bitcoin and ether

Correlation data favors Solana

Bitcoin's spot exchange-traded products attracted more than $55 billion in inflows since their launch in January 2024, opening the door for institutional capital to flow into alternative cryptocurrencies. Ether and Solana ETPs followed, giving wealth managers new tools to build crypto-exposed portfolios.

The key metric for diversification isn't price movement alone—it's correlation. Over the four years through April 2026, bitcoin's correlation with ether was 0.78, meaning the two assets moved together most of the time. By contrast, SOL's correlation with bitcoin was 0.72—a meaningful gap for a portfolio manager seeking to reduce concentration risk.

SOL's correlation with the S&P 500 Index was slightly lower than both bitcoin's and ether's, giving it an edge for investors balancing crypto with traditional equities.

Volatility trade-off

The catch is volatility. Since the start of 2026, ether and SOL have exhibited volatility approximately 35% and 44% higher than bitcoin, respectively. Ether and SOL are generally less liquid and more volatile than bitcoin, which means larger price swings and wider bid-ask spreads.

Galindo's argument hinges on a simple principle: a volatile asset that moves independently of your portfolio can still improve diversification. An asset that moves in lockstep with the rest of your holdings, no matter how stable, doesn't.

Bitcoin has historically exhibited relatively low correlations with traditional asset classes over full four-year crypto cycles. The question for institutional allocators is whether Solana's lower correlation with bitcoin and equities justifies its higher volatility in a diversified portfolio.
