The software sector is having what you might call a rough week. Actually, make that a rough eight days. Software stocks plunged Thursday for their eighth consecutive session, putting them on track for their longest losing streak since May 2021. The culprit? A growing anxiety among investors that artificial intelligence might actually cannibalize demand across the software-as-a-service economy rather than supercharge it.

The iShares Expanded Tech-Software Sector ETF (IGV) dropped 1.9% on the day, extending its drawdown from late-October highs to roughly 30%. That's not a correction anymore, that's a full-blown rout.

Even Palantir Technologies Inc. (PLTR), which has been positioned as the golden child of the AI-driven software rally, couldn't escape the carnage. Shares fell 4.4% Thursday, following an 11% nosedive the day before. When the AI poster child is getting hammered, you know sentiment has turned.

Crypto Chaos Amplifies the Pain

The biggest decliners in the software space were tied to cryptocurrency markets, where Bitcoin (BTC) slid 9% to $66,000, hitting levels last seen in October 2024. The crypto winter vibes spread quickly to related stocks.

Strategy Inc. (MSTR), Mara Holdings Inc. (MARA), and CleanSpark Inc. (CLSK) each plummeted about 12%. These are companies whose fortunes are tied directly to Bitcoin's price movements, so when the digital currency tanks, they follow suit with mathematical precision.

The pain wasn't confined to crypto and software. Commodities suffered broad-based declines, with silver plunging 13% to $76 an ounce and gold slipping 2% to $4,865 per ounce. It was one of those days where everything seemed to be going down together, which tends to make investors nervous about what's really driving the selling.

Major Indices Slip as Tech Weighs

All major U.S. stock averages traded modestly lower Thursday, with the Nasdaq 100 headed for a third straight session of losses. The tech-heavy index has been particularly vulnerable given its exposure to the software sector bloodbath.

Earnings Season Brings Mixed Signals

Among post-earnings movers, Alphabet Inc. (GOOGL) fell 3% despite beating estimates. The problem? Ballooning capital expenditure revived concerns over near-term shareholder returns. Investors are starting to wonder when all that AI infrastructure spending will actually translate into profits.

Qualcomm Inc. (QCOM) slumped nearly 7% after issuing weaker-than-expected guidance, while private equity giant KKR & Co. Inc. (KKR) fell 5% after posting a double miss on both earnings and revenue.

The day's biggest disaster belonged to Estée Lauder Companies Inc. (EL), which plummeted 23% and was on track for the worst session in the company's 30-year history. While quarterly adjusted earnings and revenue actually met expectations, the company warned that tariffs would weigh on fiscal 2026 profitability. That's the kind of forward-looking statement that sends investors running for the exits.

It wasn't all doom and gloom, though. Uber Technologies Inc. (UBER) rallied 4% despite an earnings miss, as investors reacted positively to management commentary on autonomous vehicle expansion. Sometimes the story matters more than the numbers. Arm Holdings plc (ARM) jumped 7% in another bright spot.

Amazon.com Inc. (AMZN) fell 3.4% ahead of its fourth-quarter earnings report due after the bell. The stock was trading nervous ahead of what's always one of the most closely watched earnings releases of any quarter.

Thursday's Performance in Major U.S. Indices, ETFs

Looking at the broader ETF landscape, the selling was fairly uniform across the board:

• The Vanguard S&P 500 ETF slipped 0.7% to $626.52
• The SPDR Dow Jones Industrial Average fell 0.64% to $491.58
• The tech-heavy Invesco QQQ Trust Series declined 0.74% to $601.29
• The iShares Russell 2000 ETF dropped 0.84% to $258.33
• The Utilities Select Sector SPDR Fund outperformed, up 0.28%, while the Materials Select Sector SPDR Fund lagged badly, down 2.35%

The market's bifurcation was on full display in the Russell 1000's top movers. While healthcare distributor McKesson soared 15.77% and industrial names like Regal Rexnord and ITT posted strong gains, the losers list was dominated by the day's themes: crypto exposure, commodities concerns, and tariff fears. Ralliant Corporation led the decliners down 29.23%, followed by FMC Corporation falling 21.20% and Estée Lauder's historic plunge.

What we're seeing is a market grappling with fundamental questions about where the next phase of growth comes from. The AI narrative that powered software stocks to dizzying heights is now being questioned. Will AI tools reduce the need for multiple SaaS subscriptions? Will they make software cheaper and more commoditized? These are the questions keeping software investors up at night, and judging by eight straight days of selling, they don't have good answers yet.
