Market Overview - On February 13, 2026, a significant asset sell-off occurred in global financial markets, particularly impacting U.S. stock indices. The Dow Jones Industrial Average fell by 669.42 points (1.34%) to close at 49,451.98, while the Nasdaq Composite Index dropped 469.32 points (2.03%) to 22,597.15. The S&P 500 Index also declined by 108.71 points (1.57%) to 6,832.76 [1].

COMEX gold futures fell by 3.08% to $4,941.4 per ounce, while COMEX silver futures plummeted by 10.62% to $75.01 per ounce [2][3].

Over 40 Chinese concept stocks experienced substantial declines, with Tencent Music down 10.57% and Alibaba down 3.40% [3][4][6]. Employment Data Influence - The catalyst for this market turmoil was a strong U.S. employment report released on February 11, showing a non-farm payroll increase of 130,000 in January, significantly above the expected 70,000. This led to a shift in market expectations regarding Federal Reserve interest rate cuts, with the probability of a March rate cut dropping from 19.6% to 6% [5][6]. Capital Expenditure Concerns - Major tech companies announced aggressive capital expenditure plans for 2026, with Alphabet projecting $175 billion to $185 billion and Amazon estimating $200 billion, both nearly doubling their 2025 expenditures. This raised investor concerns about the return on such investments, especially as many companies reported record profits but saw stock price declines [10][11]. Market Sentiment and Volatility - The market's fear and volatility increased sharply, with the VIX index rising significantly. The sell-off was exacerbated by algorithm-driven trading, which triggered stop-loss orders and led to extreme price movements [15][16][17]. Global Market Impact - The financial turmoil that began in Wall Street quickly spread to global markets, with Asian and European stock markets opening lower in response to the U.S. declines [18].
