Why premarket matters

The premarket range is the first price discovery of the day. News, earnings and overseas moves get priced in before the open, so the premarket high and low often act as the first resistance and support once regular trading starts at 9:30 AM ET.

How traders use it

  • A break above the premarket high after the open is read as buyers in control.
  • A break below the premarket low is read as sellers in control.
  • Opening inside the range often means a slow, two-sided start: wait for one side to break.

What happened over the last 10 sessions

  • The premarket high was set before 6:00 AM on 4 of 10 sessions, and in the last 30 minutes before the open on 1 of 10.
  • The session closed up 4 times and down 6 times.
  • Gap: ROK opened Nov 5 at $402.96, a gap down of 9.2% from $443.88; the gap was not filled.
  • Round numbers nearby: $370.00, $380.00, $390.00.
