Morgan Stanley Says Solana Diversifies Bitcoin Better Than Ethereum
Which cryptocurrency pairs better with Bitcoin? Morgan Stanley strategist Denny Galindo picks Solana ($SOL) over Ethereum ($ETH), based on how their prices have moved in the past. The timing matters. He made the case during a strong week for crypto, when Bitcoin climbed above $64,000 after US CPI and PPI figures came in below forecasts. Then resistance hit. Long-term holders and recent buyers were selling BTC, limiting the rally despite the better inflation news. My take: the selling matters as much as the headline price.
Bitcoin, Ethereum, and much of the altcoin market gained after the US inflation reports. Traders read the softer figures as another sign that the Federal Reserve might cut interest rates—a setup that tends to help speculative assets such as crypto. But the usual “lower inflation means higher crypto” explanation is only half right. Bitcoin holders were not all responding the same way. Some may have been taking profits. Others may simply have wanted less risk. I’ll be honest: either explanation involves some guesswork. The data shows steady selling by long-term and short-term holders, and that was enough to slow Bitcoin’s rally while the wider market stayed positive.
Speaking to CoinDesk, Galindo said Solana could diversify a Bitcoin-heavy portfolio better than Ethereum. His case rests on two numbers. Through April 2026, Bitcoin’s correlation with Ethereum was 0.78, while its correlation with Solana was 0.72. A score of 1 would mean the assets moved in perfect sync. Why does this matter? Because Solana’s lower figure suggests it behaved a bit more independently. The difference is only 0.06. Hardly a dramatic split. Still, investors looking beyond Bitcoin may care about it as spot Bitcoin ETFs expand and the market weighs more Ethereum and Solana funds.
Galindo said Solana also had a slightly lower correlation with the S&P 500 than either Bitcoin or Ethereum. That could be useful for someone spreading risk between crypto and traditional markets. It does not make SOL a safe haven. Not even close. Crypto can plunge when stocks sell off, and Solana has been especially volatile. Counter to the usual diversification pitch, a weaker correlation does not automatically mean lower risk. Even so, investors who do not want every holding moving in the same direction may find SOL’s weaker link to the S&P 500 appealing. Bitcoin has sometimes held up during geopolitical turmoil, but the case for any cryptocurrency as reliable protection is still shaky. And there is another catch, as Galindo acknowledged: SOL is more volatile than ETH.
What this means
Morgan Stanley’s analysis shows how institutional investors compare cryptocurrencies: not by familiarity alone, but by how each asset changes the risk in a portfolio they already own. Correlation helps answer that question. It can also shift quickly as market conditions change. More institutional interest might bring extra capital and deeper liquidity to SOL, though neither is assured. ETF approvals and investor demand will count. So will Solana’s technical performance. Is a 0.06 difference enough to rebuild a portfolio around? I don’t think so. I would read the 0.06 correlation difference as an interesting signal, not a final answer.
The next test is whether Solana’s lower correlation holds under different market conditions, especially once spot Ethereum ETFs and any future Solana ETFs are trading. Ordinary rallies reveal only so much; steep selloffs may tell investors more. If SOL keeps moving differently from BTC and ETH, Galindo’s argument gets stronger. If their correlations draw closer, the argument mostly falls apart. Simple as that. ETF regulation matters because approval could change both SOL’s owners and its trading patterns. FOMC minutes and upcoming inflation reports may shape demand in the near term as well. To my eye, that is the part worth watching—not one tidy historical reading. Correlation only describes what prices did before. It cannot guarantee shelter in the next crash.
FAQ
Q: Why does Galindo consider Solana a better Bitcoin diversifier than Ethereum?
A: Solana’s correlation with Bitcoin was 0.72 through April 2026, compared with 0.78 for Ethereum. The lower figure means SOL moved a little more independently from BTC during that period. My read: “a little” is doing important work here.
Q: How does Solana compare with Bitcoin and Ethereum against the S&P 500?
A: Galindo said Solana had a slightly lower correlation with the S&P 500 than Bitcoin and Ethereum did. That difference could help investors spread risk between cryptocurrencies and stocks, but it does not turn SOL into a defensive asset.
Q: What is the downside of using Solana for diversification?
A: Solana is more volatile than Ethereum, so any diversification benefit comes with the risk of bigger price swings. Is that a minor caveat? No. It is the central tradeoff.
Q: Why are institutions paying more attention to crypto diversification?
A: Spot Bitcoin ETFs have made cryptocurrency easier for institutions to buy. Ethereum ETFs and potential Solana ETFs give portfolio managers more choices. Bitcoin no longer has to be the automatic option.
Q: What would support Morgan Stanley’s argument?
A: Investors can compare SOL with BTC and ETH during market stress and after new ETFs begin trading. If the correlation gap lasts, it supports Galindo’s view. If the gap narrows, his case becomes weaker. Most commentary focuses on the next rally; I think the next serious selloff will provide the cleaner test.
