Bitcoin's 'Red September' Pattern Continues with Uncertain Future

The phenomenon known as 'Red September' has been observed in both Bitcoin and the U.S. stock market, where losses occur more frequently than gains during this time period.

Data from CoinGlass shows that out of 13 complete years since 2013, Bitcoin has recorded declines in September eight times, with an average return rate of -2.97% and a median of -2.44%. This trend is not unique to the crypto market, as researchers at Yardeni have found a similar pattern in the S&P 500 index since 1928.

The reasons behind 'Red September' are unclear, but various theories include tax-loss harvesting by mutual funds and institutional traders returning from summer vacations to execute hedging reductions. The Federal Reserve's mid-month meetings may also contribute to volatility during this time period.
