The first trading day of the new year saw an interesting divergence in the US stock market. The Dow Jones Industrial Average rose by 0.7%, the S&P 500 index edged up by 0.2%, but the Nasdaq Composite slightly declined by 0.04%. This stark contrast mainly stems from investors' reassessment of the complex expectations for 2026—traditional blue-chip and financial stocks performed strongly, while tech stocks faced profit-taking pressures at high levels.

Even more noteworthy is the "independent show" in the crypto market. On the same day, Bitcoin rose by 1.9%, surpassing $89,854, completely unaffected by the divergence in the stock market. What does this reflect? Over the past two years, the correlation coefficient between BTC and the Nasdaq reached as high as 0.8, almost dancing in sync. But now, this "binding" is loosening, and the correlation is clearly decreasing.

Why is there decoupling? First, the crypto market has its own catalysts—ETF inflows, improved regulatory environment, etc.—no longer relying entirely on macro liquidity. Second, institutional investors' perceptions are shifting, beginning to view crypto as an independent asset class rather than a "subsidiary" of tech stocks. Third, Bitcoin's safe-haven attributes are strengthening; rising geopolitical risks may even push up its price.

From an investment perspective, this independence is actually good news. The crypto market is maturing and won't completely follow stock market rises and falls, providing investors with a rare diversification tool. Currently, the correlation between stocks and bonds is high, making crypto an "alternative option."

But risks cannot be ignored. If the Nasdaq encounters a systemic shock, such as a tech bubble burst, the crypto market will find it hard to be completely immune—after all, many crypto investors also hold tech stocks, making contagion difficult to avoid.

In practical operations, this correlation can be leveraged to rotate across markets: during stock market adjustments, allocate to crypto; during crypto volatility, increase stock holdings. Only then can true diversification be achieved.
