The analysis focuses on NVDA and QQQ using weekly charts. NVDA is trading around 179.94, a two-and-a-half-year channel top. A close above 182.70 would signal a new high settlement price, potentially nudging NVDA into a buy. Target for NVDA is 219.64 by year end based on April low from January high wave count. Key support at 175.19, with a potential sell-off to 149.29 if this level breaks, 168.79 could act as minor support in between. A break below 168.79 is a clear sell signal for a move to 149.29. For QQQ, a close above its two-and-a-half-year channel top is needed, otherwise hesitant to rise, with support seen around February high around 540.81.
