US stocks experience slight fluctuations: AI deal boosts tech stocks, the S&P 500 rises for six consecutive days, Treasury yields break through 4.5%
On May 14, 2025, the major U.S. stock indices were mixed. The S&P 500 index rose for the sixth consecutive day, boosted by the AI cooperation agreement between the U.S. and Saudi Arabia, as technology stocks performed strongly. The Nasdaq index also rose, while the Dow Jones index slightly declined. The yield on the 10-year U.S. Treasury note rose to 4.53%, indicating increased pressure in the bond market. Investors are focusing on the forthcoming economic data and remarks from Federal Reserve Chairman Powell to evaluate future policy directions.
S&P 500 Index Rises for Six Consecutive Days, Led by Tech Stocks
On Wednesday (May 14), the S&P 500 Index rose by 6.03 points, or 0.1%, closing at 5,892.58, marking the sixth consecutive trading day of gains. The Nasdaq Composite Index increased by 136.72 points, or 0.72%, closing at 19,146.81 points. The Dow Jones Industrial Average fell by 89.37 points, or 0.21%, closing at 42,051.06 points.
Tech stocks performed strongly, driving the broader market. The Philadelphia Semiconductor Index rose by 0.6%, with AMD surging 4.7%, NVIDIA rising 4.2%, and TSMC ADR slightly up by 0.4%. Super Micro Computer soared 16% for the second consecutive day, becoming one of the standout performers in the S&P 500 Index.
AI Agreement and Middle East Investment Boost Tech Stocks
The rise in tech stocks is closely related to the recent AI cooperation agreement between the US and Saudi Arabia. This week, US President Trump embarked on a Middle East tour, signing an investment agreement with Saudi Arabia worth up to $600 billion, covering energy, defense, and AI infrastructure. Saudi Arabia's newly established AI company, Humain, announced a partnership with US tech companies, purchasing a large number of AI chips and server equipment, with the first order including 18,000 Blackwell chips from NVIDIA and a cooperation agreement with AMD.
Additionally, AMD announced a $6 billion stock buyback plan, further boosting market confidence. Raymond James initiated coverage of Super Micro Computer with an "outperform" rating, helping its stock price surge for two consecutive days.
Treasury Yields Rise Above 4.5%, Bond Market Pressure Increases
In contrast to the optimistic sentiment in the stock market, the bond market is experiencing tension. The yield on the US 10-year Treasury rose to 4.529% on Wednesday, closing above 4.5% for the first time since February. The 30-year Treasury yield is also approaching the 5% mark. The rise in yields reflects the market's increasing expectation that the Federal Reserve will not cut interest rates in the short term, while also being influenced by increased bond supply and selling pressure from investors.
According to Zerohedge and several strategists, the bond market is facing multiple pressures, including the massive issuance of mortgage-backed securities (MBS) and corporate bonds, profit-taking from basis trades, and concerns about a potential shift in Federal Reserve policy. Some investors are betting that the 10-year yield will rise to 4.8%, indicating a strong bearish sentiment in the bond market.
Market Focuses on Economic Data and Federal Reserve Talks
Investors are closely watching the April Producer Price Index (PPI) and retail sales data to be released on Thursday to assess whether tariff policies have impacted the real economy. Andrew Graham, a partner at Jackson Square Capital, noted that the market is seeking evidence of tariff impacts permeating economic activity.
Federal Reserve Chairman Powell is also scheduled to speak on Thursday, with the market hoping to gain more clues about the future direction of monetary policy. Although the annual growth rate of the April Consumer Price Index (CPI) fell to 2.3%, the lowest since 2021, Federal Reserve officials remain vigilant about inflation risks and emphasize the need to observe more data before deciding whether to adjust interest rates.
Investor Sentiment Divided, Market Volatility Increases
Despite the recent strong rebound in the stock market, some market observers believe the rally may have entered overbought territory. Mark Hackett of Nationwide stated that the market's shift from oversold to overbought has set a record pace, potentially limiting further upside in the short term. Matt Maley of Miller Tabak believes that a pause in the S&P 500 Index's rally is a normal phenomenon.
On the other hand, Rick Gardner of RGA Investments pointed out that progress in US-China trade negotiations could bring more positive momentum to the market. The US and China recently announced mutual tariff reductions, initiating a 90-day trade truce, with the US reducing tariffs on Chinese goods from 145% to 30%, and China reducing tariffs on US goods from 125% to 10%.
