- Market Stability: By not opening on weekends, the market can stabilize and adjust to any fluctuations that may have occurred during the week. This helps to ensure a fair and efficient trading environment.
- Regulatory Requirements: U.S. financial regulations require that the stock market be closed on weekends to allow for compliance and oversight.
