The QQQ ETF, which tracks the NASDAQ-100 index, has seen price action that could indicate a potential trend reversal. The ETF reached a new all-time high on September 7th, but since then has experienced a sharp decline. Some analysts are suggesting that this could be a sign of a short-term correction or even the beginning of a larger bear market. Others believe that the decline is simply a correction within an uptrend and that the ETF will continue to rise. Regardless, investors should keep a close eye on the price action of the QQQ ETF in the coming days and weeks.
