The $QQQ just posted its ugliest day since June.

Tech got hammered. When the Nasdaq 100 drops this hard, it's usually one of three things: rate fears, earnings disappointment, or rotation out of mega-cap growth.

Worth watching what triggered the sell-off and whether this is a one-day flush or the start of something bigger. June was a different setup—different Fed expectations, different earnings cycle.

If you're holding tech-heavy positions, now's the time to check your levels and see if this is noise or a real shift in market structure.
