Premarket Stock Gainers and Losers Screener
Find premarket stock movers in ChartsWatcher. Screen dollar or percentage change from the previous close alongside premarket volume and news.
Understand the metric
What is Change from close (premarket)?
The premarket change-from-close filter measures the difference between the current premarket price and the previous closing price. Dollar and percentage options let you define the size of the overnight move. This filter is specifically for premarket behavior; it is distinct from an opening gap, which compares the previous close with the regular-session opening price.
An illustrative example
Change from close (premarket) in practice
A stock that previously closed at $10 and trades at $11.20 in premarket shows a $1.20 gain, or 12%. That is a premarket observation. Its eventual regular-session opening price could be different, producing a different gap-from-close value when trading opens.
Make it part of your workflow
A more deliberate stock screen.
Combine this filter with premarket volume in a ChartsWatcher preparation workspace to gather names moving before the open. Add news recency to investigate fresh catalysts, then keep the chart visible so you can follow whether the premarket move persists toward the regular session.
ChartsWatcher lets you combine this filter with other criteria in a toplist and rank the results by the columns you care about. Keep the shortlist beside charts, stock news, and watchlists in your own layout.
