In her 2026 outlook, ARK Invest CEO Cathie Wood stated that Bitcoin's low correlation with major asset classes such as gold, stocks, and bonds makes it a powerful tool for portfolio diversification and higher returns per unit of risk. ARK's weekly return analysis from January 2020 to early January 2026 shows that Bitcoin's correlation with gold is moderate at 0.14, significantly lower than the S&P 500's correlation with bonds at 0.27. Bitcoin has the lowest correlation with bonds (0.06), slightly higher correlations with gold and real estate investment trusts (REITs), and the highest correlation with the S&P 500 at 0.28. Even at peak times, Bitcoin's correlation remains significantly lower than that of traditional asset pairs, such as the S&P 500 and REITs (correlation 0.79).
