The Same Stock, A Different Market

Premarket and after-hours sessions run on a fraction of the liquidity, which changes what every price on the screen means.

What the Lesson Covers

  1. 0:00The stock is the same after hours. The market around it is not.
  2. 0:05The sessions. Premarket, the regular session, then after-hours. Only the middle one is deep.
  3. 0:14What thin liquidity does. Spreads widen, single orders move price, and a headline can swing it violently.
  4. 0:23Why your chart looks different. Most charts hide extended hours by default, so gaps appear where trading happened.
  5. 0:31The practical rule. Extended-hours prices are real trades, but they are a small and unrepresentative sample.
  6. 0:39Treat an after-hours move as a hint, not as the verdict.
