Tech Stocks Try to Steady as Nasdaq100 AI Selloff Spreads across Markets

Why Is the Nasdaq 100 Facing Such Intense Pressure?

The Nasdaq 100 is under pressure as investors grow more cautious about tech companies investing heavily in artificial intelligence (AI). Concerns about rising debt and whether these investments will deliver sufficient profits are weighing on market sentiment.

At the same time, persistent inflation and elevated US Treasury yields are making technology stocks less attractive. 

AI Infrastructure Debt Weighs Heavily

The growing cost of building AI infrastructure is becoming a major concern for investors. Companies are spending billions of dollars on data centers, computing power, and other resources needed to support AI development. However, investors are questioning whether future earnings will justify these expenses.

A report cited by Google Finance on October 16, 2026, highlighted investor concerns about whether upcoming corporate earnings would support the massive cost of data center investments.

Nvidia-backed data centre operator CoreWeave fell 12% on Friday. Investors are concerned about a debt-heavy balance sheet and cash flow.

Meanwhile, Bloomberg reported on October 19, 2026, that Nvidia-backed Nscale was facing resistance to its proposed US$30 billion IPO valuation. Deutsche Bank analysts said,

“Markets have just had an incredibly tumultuous 24 hours, as a strong US CPI print was then followed up with mounting fears around the AI trade.”

Persistent Inflation Fuels Rate Hike Jitters

Persistent inflation is adding another challenge for the stock market. The September Consumer Price Index (CPI) reportedly rose to 3.7% year over year, while gasoline prices increased by 9.1%. The Producer Price Index (PPI) also climbed 6.3% annually.

These figures, reported on October 14, 2026, have raised concerns about how quickly inflation will return to the Federal Reserve's target.

If inflation remains elevated, the Fed may need to maintain restrictive monetary policy for longer than investors expect. Higher interest rates can increase borrowing costs and reduce the present value of companies' expected future earnings.

This is particularly important for technology stocks, whose valuations often depend on expectations of strong earnings growth in the years ahead. As a result, uncertainty over the Fed's next move is adding to selling pressure across the Nasdaq 100.

Rising Treasury Yields Weighing on Tech Stocks

Rising US Treasury yields are also weighing on technology stocks. The benchmark 10-year Treasury yield reportedly moved above 5.2% during recent trading before settling near 5.08% toward the end of the week.

Higher Treasury yields can make government bonds more attractive relative to stocks, particularly growth-oriented companies that pay little or no dividends.

They can also increase borrowing costs for businesses and reduce the value investors place on future earnings. This creates additional pressure on tech companies already facing questions about AI spending and debt.

As investors become more cautious, some are moving away from riskier assets. This shift has contributed to the Nasdaq 100's recent decline.

Kyle Rodda, a senior analyst at Capital.com in Melbourne, described the market environment on October 18, 2026, as "a classic period of heightened uncertainty."

Technical Indicators

The Nasdaq 100 closed at 29,187.55 on Friday, October 16, 2026, after falling 6.52% from its October 6 closing level of 31,224.69.

The Nasdaq 100 remains under short-term pressure following last week's heavy selling. A sustained recovery would be needed to suggest that buyers are regaining control.

A 10% correction from the October 6 closing level of 31,224.69 would place the Nasdaq 100 at approximately 28,102.22.

Resistance: 29,600, 30,000

Support: 29,000, 28,100

What Should Traders Do Now?

• Monitor AI Earnings: Watch upcoming third-quarter earnings reports from major technology companies, including Tesla and Meta Platforms. Strong earnings and positive guidance could help restore investor confidence, while disappointing results may extend the sell-off.
• Watch Key Support Levels: The 29,000 level is an important area to monitor. If the Nasdaq 100 breaks below its reported Friday low of 29,073.29, selling pressure could increase, potentially exposing the index to the 28,100 area.
• Track Market Volatility: The VIX has risen sharply, reflecting greater uncertainty about near-term market movements. Index traders should account for potentially larger price swings and sudden reversals when managing their positions.
• Prepare for the Fed's Policy Decision: The Federal Reserve has entered its communications blackout period ahead of its October 28 policy announcement. Traders should monitor incoming economic data and market expectations for clues about the Fed's next interest-rate decision.
• Warning! High-Impact News Today: Canada's September Consumer Price Index (CPI) report is scheduled for release today, October 19, at 8:30 a.m. ET. The report could influence the Canadian dollar (CAD) by shaping expectations for the Bank of Canada's interest-rate policy.
