The analysis begins with NVDA on a weekly bar chart, noting the stock closed above 179.94, a 2.5-year channel top. A full wave count projects a target of 219.64. Failing to hold above 171.65 could trigger a bearish continuation to 149.29. On the daily chart, intraday resistance is identified at 175.72 and 179.81. A break or open above these may target 186.39. Conversely, a close below 171.65 invalidates the bullish setup. The QQQ's channel top needs to lend further support. If it can close above this then it can lead to upward bullish trend.
