If QQQ can hold above 635 today and break through 638 with volume, the bulls will enter an accelerated extension phase, with the target zone above at 640～645. If there is a pullback during the session, short-term support is at 625～628. A drop below 622 with volume would indicate a short-term correction after a rally, likely testing around 615. However, I believe it has officially entered the second wave of the main uptrend. Cipher B maintains a strong bullish opening, OBV is steadily rising, and the Bollinger upper band continues to expand—all indicating the bulls are in control. Hold 625, attack 635, and aim for 645. At this stage, it's better to hold rather than anticipate a reversal unless there are two consecutive days closing below 622, in which case short-term cooling may be considered.$Invesco QQQ Trust(QQQ.US)$Meta Platforms(META.US)$Destiny Tech100(DXYZ.US)$Microsoft(MSFT.US)$Unitedhealth(UNH.US)$Alphabet - C(GOOG.US)$NVIDIA(NVDA.US)$Nebius(NBIS.US)$Tesla(TSLA.US)$Alibaba(BABA.US)$Intel(INTC.US)$AMD(AMD.US)$Qualcomm(QCOM.US)$Apple(AAPL.US)$Paypal(PYPL.US)
