As the financial landscape evolves, the role of Bitcoin in investment portfolios is increasingly under scrutiny. Some investors advocate for Bitcoin as a valuable diversification tool, given its potential to behave differently from traditional assets like stocks and bonds. In contrast, others highlight its significant volatility, suggesting that it may heighten, rather than lessen, overall portfolio risk.
Recently, Jurrien Timmer, Fidelity’s Global Macro Director, shared insights on this topic via his X account. He noted a shift in portfolio strategies, moving from the classic 60% equities and 40% bonds model to a more diversified approach consisting of 60% equities, 20% bonds, and 20% allocated to alternative assets.

Bitcoin’s Position in Modern Portfolios
Timmer’s updated model reflects the changing economic environment post-COVID-19, and he argues that this new structure remains pertinent today. Under this model, 60% of the portfolio is dedicated to global equities, while the 20% set aside for alternative assets includes a mix of investments, such as gold, commodities, cash, Bitcoin, Real Estate Investment Trusts (REITs), and managed futures.
According to Timmer, Bitcoin’s correlation with the S&P 500 stands around 30%, and it shows no correlation with U.S. Treasury bonds. He believes this indicates that Bitcoin can effectively contribute to diversification within an investment portfolio.
However, he emphasized that his analysis is not a finely tuned portfolio model but rather a “roughly prepared” example of asset allocation and should not be interpreted as specific investment advice. Timmer has previously speculated that Bitcoin could reach a price of $300,000 by 2029 based on a power law model.
As the conversation around cryptocurrency continues to develop, the debate over its place in investment strategies remains heated, with opinions divided among investors and financial experts alike.
