US stocks plummeted Thursday as the Dow dropped 403 points amid mounting concerns about expensive tech stocks and troubling job market data. The S&P 500 fell 0.9% while the tech-heavy Nasdaq Composite slid 1.44%, triggering extreme fear across Wall Street as volatility surged and risk-off sentiment gripped investors.
The selloff spread across markets as troubling signs emerged from employment figures showing a bleak outlook for workers. Layoff announcements in October reached the highest increase for that month since 2003, according to Challenger, Gray & Christmas data, sending shockwaves through trading floors and pushing the VIX—Wall Street’s fear gauge—up 11%.
Tech Giants Lead Market Decline
Expensive tech stocks bore the brunt of selling pressure as nerves about a potential bubble intensified. Chipmaker Advanced Micro Devices (AMD) slid 6.3%, while Palantir (PLTR) tumbled 5.5% and Nvidia (NVDA) dropped 3%. The tech sector’s expensive valuations have become increasingly difficult to justify as AI stocks face renewed scrutiny.
CNN’s Fear and Greed index hovered in “extreme fear” territory, reflecting widespread anxiety about whether tech companies can maintain their gains. The sector’s dominance has made the broader stock market increasingly reliant on these firms’ performance, creating vulnerability when sentiment shifts.
Warren Buffett’s Warning Signal Flashes Red
Legendary investor Warren Buffett’s favorite market indicator is now flashing a serious warning sign. The Buffett Indicator, which compares the total value of the stock market to economic growth, hit a record high above 200%—suggesting the market is strongly overvalued. This measure has historically preceded major corrections.
“The S&P 500 today is at historically extreme valuations,” said Torsten Slok, chief economist at Apollo Global Management, in a note to clients. His assessment echoes growing unease among seasoned investors who remember previous bubble environments.
Investors Flee to Safety of Government Bonds
Investors rushed to buy Treasuries as shelter from the storm, pushing yields lower across the curve. US Treasury bonds remain safe bets when signs point to a slowdown in the economy, and the weakening labor market has begun to bolster arguments for the Federal Reserve to cut interest rates more aggressively.
The announced jobs cuts data from Challenger, Gray & Christmas showed troubling acceleration in workforce reductions. Investors tend to lock in current yields when the Fed signals potential rate cuts, making government bonds increasingly attractive as quality fixed income investments. “With yields still attractive and likely to fall, we continue to believe that quality fixed income offers an appealing combination of income and the potential to perform well in the event of slowing economic activity and further rate cuts,” explained Ulrike Hoffmann-Burchardi, global head of equities at UBS Global Wealth Management, in her note.
Trump Tariff Case Adds Uncertainty
Wall Street remained attuned this week to the Supreme Court’s deliberations and oral arguments about the legality of President Donald Trump’s sweeping global tariff regime that relies on an emergency powers law. The case has added another layer of uncertainty for markets already grappling with valuation concerns.
Investors in recent months have looked past concerns about tariffs, while the revenue collected has helped assuage bond investors’ nerves about enormous US deficits. Though a decision isn’t immediately expected, the outcome could prove to be a thorny issue for investors if the tariffs are struck down—despite the headache they caused earlier this year.
From Hot Streak to Cold Reality
The Dow had been riding a monthslong hot streak, having rose every month from April through October, posting its best monthly winning streak since the end of 2017. That momentum now appears to have hit a wall as concerns about sustainability mount.
Stocks have climbed higher on strong corporate earnings and enthusiasm about Artificial Intelligence, yet the concentration of gains in tech has become problematic. Even Bitcoin reflected the risk-off sentiment, sliding 2.4% to hover around $101,500. The cryptocurrency has fallen almost 20% since reaching an all-time high above $126,000 one month ago.
