UPDATE: The stock market is in turmoil as October 10, 2023 saw the S&P 500 plunge 2.7%—its steepest drop since April—amid renewed trade tensions with China. With investors on edge, the critical question remains: Will October bring more volatility or a turnaround?

New reports confirm that the S&P 500, Nasdaq, and Dow Jones are facing significant headwinds as October is notorious for dramatic sell-offs. Historical events, such as the 20.5% single-day crash on October 19, 1987, and the market’s 16% decline during the Great Recession in October 2008, have left many investors anxious.

Just announced, President Trump has imposed an additional 100% tariff on China, reigniting fears of a prolonged trade war. This news has sent shockwaves through the market, prompting sharp declines. The S&P 500’s recent performance raises concerns about October’s potential for further losses, particularly considering its mixed returns over the past five years.

The data shows:
2024: -0.99%
2023: -2.20%
2022: 7.99%
2021: 6.91%
2020: -2.77%

With the S&P 500 historically finishing higher in October 59% of the time since 1950, there is still hope for a rebound. Despite October’s reputation for shocks, the Stock Trader’s Almanac indicates an average return of 0.9%, ranking it as the 7th best month for the index. However, such returns pale in comparison to the following month—November—where gains occur 69% of the time.

Amid these developments, analysts warn of the risks ahead. The S&P 500’s current price-to-earnings (P/E) ratio stands at 22.8, a level often associated with lackluster returns. Additionally, economic indicators are showing cracks. The unemployment rate hit 4.3% in August, the highest rate since 2021. Preliminary data from Bank of America and ADP suggests the job market may have worsened in September.

The Federal Reserve’s recent decision to cut interest rates by 0.25% on September 20 aimed to bolster the economy. Optimistically, the market is anticipating another rate cut on October 29, with the odds of a 0.25% cut currently at 98%. However, if these cuts do not sufficiently stimulate growth, a slowing economy could hinder market recovery.

As October unfolds, many investors view potential market declines as a “buy-the-dip” opportunity, particularly with historically strong months like November and December on the horizon. Yet, the looming uncertainty from ongoing trade tensions and economic data suggests caution.

What happens next will be crucial. Investors should watch closely for upcoming announcements from the Federal Reserve and any developments in U.S.-China trade relations. The market’s response to these factors could shape the trajectory of stocks in the coming weeks.

Stay tuned for the latest updates on this developing story, as the market navigates the complexities of October’s historical volatility.
