Bank of America released a report on the 27th (local time) advising investors to adopt defensive strategies as US stocks enter the historically weak August-October period. According to Business Insider, BofA's analysis shows the S&P 500 has averaged a 0.02% decline during August-October since 1928, with an average correction of 7.35% in down years. The recommendation comes amid heightened market volatility driven by Middle East geopolitical uncertainty and shifting AI investment flows, with memory-related stocks that led this year's gains now facing profit-taking pressure.
BofA Analyzes S&P 500 Historical August-October Performance Since 1928
Bank of America's report analyzed S&P 500 performance data spanning from 1928 to present. The analysis revealed that the August-October period has historically been a weak phase for US stocks, with the index averaging a 0.02% decline during these three months. In years when stocks declined, the average correction reached 7.35%. BofA explained that this period typically sees investors adopting stronger defensive tendencies.
Current Market Volatility Driven by Geopolitical Risks and AI Investment Shifts
Recent stock markets have exhibited high volatility amid geopolitical uncertainty in the Middle East region and changes in artificial intelligence-related investment flows. Memory-related stocks that drove market gains this year are now showing slowed upward momentum as they face profit-taking pressure.
Historical Data Shows Strong October-December Stock Performance
BofA's analysis found that strong rebound periods have often followed seasonal weakness. The October-December period has been a representative phase of strong stock market performance since 1928, with the S&P 500 rising approximately 74% of the time during this interval.
BofA Strategists Recommend Defensive Positioning for July-August
BofA strategists stated that "the seasonal August-October adjustment can become a buying opportunity if supported by technical indicators." They added that "the weak August-October flow can serve as an opportunity to reduce risk or build hedge positions in July-August, then prepare for the strong November-January period."
Interest Rates and Energy Prices Identified as Key Market Variables
BofA explained that interest rates, energy prices, and the election schedule could act as major variables for future stock markets. Market concerns have emerged that rising energy prices could reignite inflation pressure, weakening Federal Reserve rate cut expectations and leading to long-term interest rate increases. Ned Davis Research analyzed in a recent report that an environment where energy prices and bond yields rise simultaneously was a characteristic that appeared before major past bear markets. Goldman Sachs also analyzed that in every midterm election year since 1974, the S&P 500's median return from early August to the November election day was 0%.
