QQQ saw some selling pressure kick in today—down 0.83% with price action closing beneath the 20-day moving average. That's the kind of breakdown that usually catches attention in the charts. Looking ahead, the lower Bollinger Band around 605 is shaping up as the next key level to watch. Could see a test there as early as Friday if momentum stays weak. Traders will want to keep tabs on how price interacts with that zone—could be a bounce point or signal further downside depending on what volume shows up.
