Technology stocks sold off sharply this week as investor confidence in the AI trade faltered, with the Nasdaq 100 falling more than 6 per cent on Thursday before rebounding nearly 2 per cent on Friday. Volatility gauges spiked and credit markets showed stress, particularly around CoreWeave debt.
Why it matters
Investors' rising demand for protection against debt defaults and a surge in volatility can raise the cost and availability of credit and move retirement and brokerage account values. The reversal in the Nasdaq 100 after a single sharp drop shows how quickly sentiment around AI-linked stocks can change.
The Nasdaq 100 dropped more than 6 per cent on Thursday before gaining nearly 2 per cent on Friday, while the VIX climbed above 28 on Thursday, its highest level since late March. Five-year CoreWeave debt default-protection spreads surged past 1,000 basis points to record highs.
The details
Credit default swaps work like insurance on a bond, so when their spreads widen, investors are paying more to hedge the risk that a borrower defaults. Spreads on CoreWeave debt, along with those for SpaceX and Intel, jumped this week, and the premium on US high-yield corporate credit rose to its highest level since the Liberation Day market turmoil of April 2025. At the same time, cash funds drew a $140 billion inflow in the week to Wednesday, signaling that many investors moved money toward safety.
Timeline
Thursday, November 5, 2026: The Nasdaq 100 plunged more than 6 per cent and the VIX rose above 28.
Friday, November 6, 2026: The Nasdaq 100 rebounded nearly 2 per cent.
October 2026: The MOVE index hit a six-month high.
Money Landscape
The current credit stress is the most severe since the April 2025 Liberation Day turmoil, when high-yield premiums last peaked at similar levels. Even as US 10-year Treasury yields have fallen 50 basis points from last month's peaks above 5 per cent, risk premiums in corporate credit have widened.
If you hold brokerage or retirement accounts with significant technology-sector exposure, this week's swings show how quickly portfolio values can move in both directions. Borrowing costs for companies with lower credit ratings may rise as default-protection premiums widen, which can affect the broader cost of corporate debt.
The takeaway
Sharp single-day moves in the Nasdaq 100 and rising credit stress can signal a shift in sentiment that is not yet settled. Review your portfolio's concentration in technology and consider discussing your risk tolerance with a qualified financial professional.
