Jurrien Timmer, director of global macro at Fidelity, said that Bitcoin's Shape Ratio of +0.97 over the past five years is worth paying attention to, which exceeds the S&P 500 index SPX (+0.74) and the US 60/40 portfolio (+0.73) and other investment categories, indicating that despite the volatility of the digital asset market, the risk-reward of Bitcoin is in a very balanced state over five years, and the returns obtained are roughly in line with the risks taken by investors. The Sharpe ratio, also known as the Sharpe Ratio, calculates how much excess return a portfolio will generate for each unit of total risk. The ratio is based on the concept of the Capital Allocation Line (CAL) and is the most common measurement ratio in the market. When the assets in the portfolio are risky assets, the Sharpe ratio is applied. The Sharpe Ratio represents that investors can get a few points of excess return for every extra point of risk; if it is greater than 1, it means that the return rate of the fund is higher than the risk of Fluctuation; if it is less than 1, it means that the risk of fund operation is greater than the rate of return.
