Prediction: Oct. 21 Will Be a Huge Day for the Stock Market

Meta Platforms is set to report Q3 earnings on Oct. 21, marking the start of earnings season for the 'Magnificent Seven' tech companies. Investors are closely watching to see if massive AI infrastructure spending translates into revenue growth. Meta's capex-to-revenue ratio has reached 35% and could climb further, raising concerns about whether AI investments will justify the spending levels. Positive results from Meta could boost AI stocks and provide direction for the broader market.
