Tech Rout: High Beta Stocks Plunge

Tech Rout Deepens, Wipes Out Billions in Market Value

A broad sell-off in the technology sector has intensified in recent weeks, erasing hundreds of billions of dollars in market capitalization and raising concerns about the sustainability of Big Tech’s investments in artificial intelligence. The downturn, which began in late January, has seen major players like Microsoft, Nvidia, and Alphabet experience significant losses.

On January 29, 2026, Microsoft Corp. Shares plummeted 10%, marking the company’s largest single-day drop since March 2020. This decline wiped out $357 billion in value, the second-largest one-day valuation destruction in stock market history. The only larger loss occurred last year with Nvidia Corp.’s $593 billion rout following the launch of DeepSeek’s low-cost AI model.

The Microsoft sell-off followed the release of the company’s earnings report on Wednesday, January 29th, which revealed record spending on artificial intelligence alongside slowing growth in its Azure cloud-computing unit. Capital expenditures rose 66% in the most recent quarter to a record $37.5 billion, according to the report.

The impact of the downturn extended beyond Microsoft. Nvidia and Alphabet each shed more than $100 billion in value at one point on Thursday, January 29th. While Alphabet shares partially recovered, closing up 0.7%, Amazon settled down 0.5%.

The recent market turbulence reflects growing investor skepticism regarding the potential return on the massive investments being made by Big Tech companies in AI. The question of whether these expenditures will ultimately translate into profits is becoming a central concern for investors.

The broader market also experienced declines on November 13, 2025, with the Dow Jones Industrial Average, S&P 500, and Nasdaq all falling sharply. The Nasdaq recorded the steepest drop as artificial intelligence-related stocks declined. Shares of Disney fell 7.8% on that day, weighing on the Dow.

Adding to the market pressure, uncertainty surrounding potential Federal Reserve interest rate cuts has also contributed to the downturn. Futures markets indicated a roughly 50% probability of a rate cut on December 10, 2025, down from over 60% a day earlier and 70% the previous week, according to CME data.

Goldman Sachs’ basket of high-beta momentum stocks, including Palantir and Applied Digital, experienced its worst day since President Trump’s April tariff announcement on November 13, 2025. Speculative stocks tied to emerging technologies like AI, quantum computing, and energy also faced significant selling pressure.

However, not all tech stocks were negatively impacted. Cisco saw its shares rise after reporting accelerated orders from AI hyperscalers, while Alibaba ticked up following reports of an overhaul to its mobile AI app.

The recent market volatility also appears to be influencing the cryptocurrency market. According to reports from January 27, 2026, crypto is beginning to trade more like a high-beta tech stock, mirroring the movements of the Nasdaq. When the Nasdaq climbs, Bitcoin and major altcoins often follow, and conversely, when bond yields rise and equity valuations compress, crypto tends to fall even further.
