Historically, September is the most challenging month for the stock market. According to an analysis by Turning Point Market Research, declines are common during this period, with an average drop of 0.7% in the S&P 500.

The Spanish stock market faces a challenging month at the beginning of September, historically considered the worst for the market. According to turningpointmarketresearch.com, the S&P 500 has experienced an average drop of 0.7% in this month over the last 69 years.

More than half the time, the S&P 500 has closed in the negative, achieving a positive performance only 44% of the time. Among the sectors, materials appear to be the most affected, with an average drop of 1.7%, while the technology sector has seen an average drop of 1.2%.

Additionally, the oil sector faces its second worst monthly balance of the year, behind May. However, the analysis also highlights a bullish exception in the price of natural gas, which has accumulated an average revaluation of 19% in September, with increases in 81% of cases.
