The recent performance of Bitcoin is closely related to the SP 500 index, but this correlation fluctuates significantly over time. For example, due to the two types of assets moving in opposite directions within the last 50 days, the correlation turned negative in June 2024. In addition, although the correlation indicator exceeded a threshold of 60% for 272 days (about 38% of that period) within two years, there is no statistical conclusion on this figure yet.
