S&P 500 and Bitcoin correlation

Earlier today, Cointelegraph reported on Fundstrat Global Advisors co-founder Tom Lee claiming that Bitcoin’s price is positively correlated with the S&P 500 (SPX) market index and is not a hedge against macroeconomic turmoil. Meanwhile, S&P 500 is almost flat over a one-year period, while Bitcoin is up 21% from $6,600 in October 2018.

Lee noted that Bitcoin’s average gain was 300% in the years when the S&P 500 was below its long-term average return. At the same time, in the years that have seen the index gaining 15% or more — BTC’s average gain was 1,800%. Lee said:

“Bitcoin’s best years have all taken place in the years where the S&P has performed very well.”
