S&P 500, Dow and Nasdaq down today: Wall Street is heading to end the week in the red as investors reacted to a surprisingly strong US jobs report and continued selling pressure in technology stocks, particularly semiconductor companies.The market's recent optimism was tested on Friday after fresh labor market data showed the US economy remains stronger than many economists expected. While strong employment is generally viewed as positive for the economy, investors worried it could give the Federal Reserve less reason to lower interest rates and may even increase the chances of another rate hike later this year.US Stock Market Today June 5: S&P 500, Nasdaq, Dow Jones Slide as Investors Exit Tech StocksThe selloff hit major indexes, S&P 500 fell 1.7%, while the Nasdaq Composite dropped 2.8% as technology shares led the decline and the Dow Jones Industrial Average also moved lower, losing more than 400 points during the session, as per a CNBC report.The weakness was concentrated in semiconductor and AI-related stocks, which have been among the market's biggest winners over the past year.Broadcom shares fell another 6% after suffering a double-digit decline the previous day. Marvell Technology and Micron Technology each dropped around 9%, while Intel and AMD lost roughly 8%.You Might Also Like:Even Nvidia, one of the strongest performers of the AI boom, declined more than 4% as investors continued rotating out of technology stocks.Strong Jobs Data Changes the US Stock Market NarrativeThe latest employment report surprised Wall Street. According to the Bureau of Labor Statistics, the US economy added 172,000 jobs in May, significantly above expectations of roughly 88,000 jobs, as per a Yahoo Finance report.The unemployment rate remained steady at 4.3%, while payroll figures for previous months were revised higher, reinforcing the view that the labor market remains resilient despite concerns about slowing growth.Several sectors drove hiring gains, including leisure and hospitality, local government, and healthcare. Together, these industries accounted for most of the new jobs added during the month.You Might Also Like:Why Investors Are Worried About Good Economic NewsNormally, strong hiring data would boost confidence about the economy. However, investors viewed the report differently.A stronger labor market could make it harder for the Federal Reserve to bring inflation back to its target level. As a result, traders increased expectations that the central bank may need to keep interest rates elevated for longer or potentially raise them again before year-end.Market pricing began reflecting growing confidence that a quarter-point rate hike could occur by December.That shift in expectations immediately pushed Treasury yields higher.US Bond Market Today: Treasury Yields Jump After Payroll ReportBond markets reacted quickly to the jobs numbers. The yield on the 10-year Treasury climbed above 4.5%, while the 30-year Treasury yield moved above 5%, as per the CNBC report.Higher yields often create challenges for technology stocks because future earnings become less valuable when discounted at higher interest rates. This helps explain why many growth-oriented companies came under pressure following the report.AI Stocks Lose Momentum After Massive Run-UpMarket participants also pointed to profit-taking after months of strong gains in AI-related stocks, as per the CNBC report.Investors have poured money into semiconductor companies and artificial intelligence plays throughout the past year. However, elevated expectations can make even solid earnings reports appear disappointing.The latest weakness in Broadcom helped accelerate concerns that the AI trade may be cooling, at least temporarily, prompting traders to lock in gains across the sector.Defensive Stocks Attract Investor InterestWhile technology struggled, some defensive sectors performed better.Consumer staples stocks gained ground as investors sought safer areas of the market. Shares of Colgate-Palmolive and Coca-Cola both advanced more than 3%.The move highlighted a broader rotation away from high-growth technology stocks and toward companies considered more stable during periods of uncertainty.Shipping and Energy Concerns Add Another Layer of RiskBeyond the jobs report, investors are also monitoring developments in global energy markets.Concerns about fuel shortages have emerged as disruptions linked to tensions involving Iran continue to affect energy supplies. Industry experts warned that shortages of marine fuel could potentially disrupt portions of the global shipping fleet in the coming months.These concerns have added to worries about inflation and supply-chain pressures, factors that could further complicate the Federal Reserve's policy decisions.Historic Winning Streak Under ThreatThe recent pullback has put major indexes on track for a weaker week.The S&P 500 is now at risk of ending a remarkable nine-week winning streak. Meanwhile, the Nasdaq is heading toward a weekly loss of roughly 3% as technology stocks continue to retreat.FAQsWhy did US stocks fall on Friday?Stocks declined after a stronger-than-expected jobs report increased expectations for higher interest rates.How many jobs were added in May?The US economy added 172,000 jobs in May.
