穆迪评级下调风波下，散户创纪录“抄底”美股

Core Viewpoint - The U.S. stock market experienced a dramatic reversal on Monday, with retail investors engaging in record "buying the dip" actions, which quickly turned around the initial decline in the S&P 500 index caused by Moody's downgrade of the U.S. credit rating, leading to gains across all three major indices [1]. Group 1: Market Performance - The S&P 500 index initially fell nearly 1.1% but rebounded to close up 5.22 points, or 0.09%, at 5963.60 points [3]. - The Dow Jones Industrial Average rose by 137.33 points, or 0.32%, closing at 42792.07 points, while the Nasdaq increased by 4.36 points, or 0.02%, to finish at 19215.46 points [3]. Group 2: Retail Investor Activity - Retail investors demonstrated significant buying power, with net purchases of U.S. stocks reaching a record $4.1 billion by noon, marking the first time this figure surpassed $4 billion before midday [3]. - Retail trading volume accounted for 36% of total market trading volume, setting a new historical high, surpassing the previous peak in late April [3]. Group 3: Investor Sentiment and Strategy - Retail investors are showing a strong belief in the market, avoiding past hesitations that led to missed opportunities during rebounds [4]. - The recent buying trend among retail investors follows a pattern seen in April when they bought stocks at record speeds during a market downturn [4]. - Wall Street strategists, including Morgan Stanley's Michael Wilson, view the market pullback triggered by Moody's downgrade as a buying opportunity, especially after the U.S.-China tariff truce reduced recession risks [4]. - HSBC's multi-asset strategy head, Max Kettner, also sees declines in risk assets as opportunities for increased investment [4]. Group 4: Specific Stock Preferences - On Monday, retail investors allocated $2.5 billion to individual stocks and $1.5 billion to exchange-traded funds (ETFs) [5]. - Tesla and Palantir were particularly favored, attracting net inflows of $675 million and $439 million, respectively [5]. - Retail investors actively increased their holdings in Bitcoin-related ETFs while continuing to reduce their positions in Nvidia [5].
