加速消化，逢低布局——通信ETF（515880）大跌点评

Core Viewpoint - The computing sector is experiencing a pullback, with overseas computing leading the decline, and both communication and consumer electronics ETFs dropping over 4% in intraday trading [1]. Group 1: Downward Factors Analysis - The recent decline in the US stock market was influenced by a significant drop in Nvidia's stock following its earnings report on November 19, leading to a 1.56% drop in the S&P 500 and a 2.15% drop in the Nasdaq [3]. - Major events such as Nvidia's earnings, the US non-farm payroll report, the Federal Reserve's meeting, and Google's Gemini 3 model have heightened market sensitivity, prompting investors to buy put options, which increased implied volatility [3]. - The mechanism known as "Vanna Crush" contributed to the stock price decline, as the rapid drop in volatility led to an increase in Delta, causing market makers to reduce their positions, further driving down stock prices [3]. Group 2: Market Outlook - The AI technology cycle is unlikely to end in the short term, with ongoing focus on the computing sector, as infrastructure investment and performance are expected to resonate positively [5]. - Nvidia's earnings exceeded expectations, indicating that demand for computing is still growing rapidly, while Google's Gemini 3 model has received positive market feedback for its innovative capabilities [5]. - The upcoming year may see a boom in components like optical modules, maintaining a high level of market activity, although short-term pullback risks should be noted [5].
