The Nasdaq-100 ETF ($QQQ) is showing signs of bullish momentum as it breaks above key resistance levels. After struggling at $486.43, it has now moved above the Value Area and surpassed yesterday's sellers. The ETF is exhibiting a '3 weeks tight' pattern just below its all-time highs, suggesting potential for further gains as the tech earnings season approaches. Analysts note that bullish opening put sales have been prevalent for months, which may keep any dips shallow. The ETF is aiming for its best close since July 16. Despite potential for choppy movement in October, the overall outlook remains optimistic for the Nasdaq.
