Nvidia Leads Tech Stock Decline, Nasdaq Hits Three-Week Low: Weighted Stock Pullback and Market Sentiment Analysis

Tech Stocks Lead Decline: Nvidia and Apple Drag Nasdaq to Three-Week Low

This week, the U.S. stock market experienced a notable pullback, with the tech-heavy Nasdaq Composite Index falling to its lowest level in three weeks. Market sentiment has shifted from optimism to caution as investors increase profit-taking pressure on high-valuation tech stocks, particularly with the sustained weakness of heavyweights Nvidia (NVDA) and Apple (AAPL), which are the main factors dragging down the index.

Nvidia and Apple: Dual Pressure on Weighted Stocks

As the absolute leader in the artificial intelligence (AI) chip sector, Nvidia's stock price has recently faced continuous pressure. Although the company's leading position in the AI computing market is undisputed, the market is beginning to worry whether its earnings growth rate can sustain its current high valuation. According to data from industry analysis firms, Nvidia's price-to-earnings ratio is at historical highs, prompting some investors to lock in profits ahead of the earnings season. Meanwhile, Apple is also grappling with concerns over weak demand, particularly as sales data in the Greater China region fell short of expectations, compounded by rising supply chain costs, leading to a sluggish stock performance. The simultaneous decline of these two stocks, with a combined market capitalization exceeding several trillion dollars, has significantly weighed on the Nasdaq index.

Technical Breakdown: Key Support Levels Breached

From a technical analysis perspective, the Nasdaq index recently broke below its upward trendline that had held for several weeks. According to market technical analysts, the index's loss of key moving averages (such as the 50-day moving average) triggered a chain reaction of algorithmic trading and stop-loss orders, accelerating the decline. Trading volume increased notably during the sell-off, indicating concentrated selling pressure. Additionally, market breadth indicators show that declining stocks far outnumber advancing ones, further confirming the deterioration in market sentiment. The index is now testing the next important support level; if this level is lost, it could trigger a deeper correction.

Market Sentiment Shift: From Euphoria to Rationality

Behind this correction is a process of market sentiment returning from extreme optimism to rationality. Previously, driven by the ongoing AI narrative and expectations of Federal Reserve rate cuts, tech stocks, especially AI-related sectors, had accumulated substantial gains. However, recent hawkish comments from Fed officials, hinting at a possible delay in the rate cut timeline, have cooled expectations for liquidity easing. According to the Fed meeting minutes, some officials expressed concerns about inflation stickiness, which has dampened bets on multiple rate cuts this year. Furthermore, geopolitical uncertainties and policy risks associated with the U.S. election year are prompting some funds to shift from risk assets to safe-haven assets, such as Treasuries and gold.

Sector Rotation and Fund Flows

Amid the tech stock pullback, the market has shown clear signs of sector rotation. Funds are moving from high-valuation tech growth stocks into defensive sectors such as utilities, healthcare, and consumer staples. According to data from fund flow monitoring agencies, the tech sector ETF experienced significant net redemptions over the past week, while defensive sectors saw net inflows. This rotation reflects investors' preference for assets with stable earnings and ample cash flow amid rising uncertainty. However, some analysts suggest that this correction may be short-term, as the long-term growth logic of the AI industry remains intact. Once valuations digest, tech stocks could regain favor with investors.

Outlook: Focus on Earnings and Policy Signals

Looking ahead, the market will closely monitor the upcoming earnings reports from tech giants and the Fed's next interest rate decision. The earnings guidance from Nvidia and Apple will be key to testing the real strength of AI demand. If earnings data exceed expectations, it could reignite confidence in tech stocks; conversely, it could exacerbate the correction pressure. Meanwhile, the Fed's policy path remains a core variable influencing market sentiment. Investors need to be wary of the risk of policy tightening due to recurring inflation data, as well as the potential impact of geopolitical conflicts on supply chains. Overall, short-term market volatility may persist, but long-term investors could consider buying the dip in tech leaders with core competitiveness.
