By AP's Morning Brief · Editor: AP Dult · Last updated: October 26, 2026
Short, sourced guides to the tools and terms that show up in the brief. Figures come only from the documents we link to.
How to read the weekly levels sheet
What each column on the SPY, QQQ and TQQQ levels sheet means, how the week-over-week change is calculated, and where every number comes from.
Leveraged ETF decay, explained
Why a fund that targets 3x the daily move of the Nasdaq-100 can return far less (or more) than 3x over a week or a month, in the prospectus's own words.
Delayed quotes, CFDs and daily yields
What you're looking at in the homepage market panels, and why those numbers won't always match your broker's.
