McDonald’s premarket gain widens to 2.27%

The signal here is the widening of the premarket move rather than its size: momentum building before the open often reflects order flow reacting to something the headline does not capture. With no disclosed catalyst, the gain is hard to attribute and easy to reverse, which makes the regular session's ability to hold the advance the more informative test. Whether the move persists past the open, or fades once full liquidity arrives, is the open question.
