How to read a QQQ/SPY news curve
A news marker becomes useful only after you understand where price was before it appeared, which session was trading, and what changed afterward.
Plain-language guides for reading timestamped headlines, reaction windows, market sessions, and QQQ-versus-SPY divergence on MarketNewsCurve.
Start with the timestamp, locate the headline on the QQQ/SPY curve, measure what happened before and after it, then compare the two ETFs without treating timing as proof of causality.
A news marker becomes useful only after you understand where price was before it appeared, which session was trading, and what changed afterward.
A clean event-window measurement needs an honest price anchor, matching endpoints, and a clear distinction between what happened before and after publication.
The same headline and percentage move can mean something different at 08:30 ET, 10:00 ET, 17:00 ET, or 23:00 ET because the trading environment changes.
QQQ and SPY often move together, but the difference between their measured reactions can reveal whether a market move was concentrated or broad.
Use the actual publication time and the price already observed at or before it.
Keep the before move separate from the 1/5/15/30/60-minute move after publication.
Compare QQQ with SPY and the market session before describing what the move may mean.
