Which statement about pre-market hours is true?

• A. They occur before the regular session from 4:00 a.m. to 9:30 a.m. ET
• B. They occur during the regular session from 9:30 a.m. to 4:00 p.m. ET
• C. They occur after 6:00 p.m. ET only
• D. They do not overlap with the regular session at all

Answer: (A)

Pre-market trading happens before the regular market session, giving investors a chance to react to overnight news and earnings before the bell. For U.S. equities, the regular session runs from 9:30 a.m. to 4:00 p.m. Eastern Time, so the pre-market window is 4:00 a.m. to 9:30 a.m. ET. This is the period described by the correct statement.

This time frame matters because liquidity is thinner and price moves can be more volatile in pre-market hours due to fewer participants and wider spreads. The other options miss the defining window: one places pre-market inside the regular session, another refers to post-market hours after the close, and one simply notes no overlap without giving the actual timeframe.
