Tech sell-off: Nasdaq tests critical support levels, value rotation deepens

Context

Since mid-June 2026, global equity markets have experienced a violent correction in the technology sector. The Nasdaq-100 dropped over 3% during the session on June 23, dragged down by Nvidia, Micron, and AMD. The Financial Times describes the situation as a "tech rout" spreading to Asian markets (Samsung, SK Hynix). The correction is part of a repricing of long-duration valuations driven by the Fed's hawkish trajectory.

Data

• Nasdaq-100: -3% on June 23, 2026; ten stocks account for most of the decline (Seeking Alpha)
• Nvidia (NVDA): approximately -12% over the last 10 days of June; impact of the doubling of prices on the Chinese black market for banned chips (FT)
• S&P 500 and Dow Jones: "deep in the red" on June 23; visible rotation toward value, dividends, and financials
• Europe: European stocks down at the open on June 23-US long-term rates weigh on valuations (Investing.com)
• Asia: Asian markets also decline; dollar at its highest in 13 months
• JPMorgan raises its S&P 500 target on June 24, calling the earnings revision "unprecedented" (Investing.com)-a contrarian bullish signal

Analysis

Three mechanisms explain the scale of the correction. (1) Hawkish Fed repricing: under Kevin Warsh, markets are pricing in a prolonged restrictive rate trajectory-long-duration assets (growth, tech) see their risk premium reopen. (2) Nvidia/China export controls: the doubling of prices for banned chips on the Chinese black market (FT, June 24) reveals lasting regulatory pressure on Nvidia’s Chinese revenue streams, a material portion of its revenue according to its latest published results. (3) Momentum → value rotation: funds are shifting back to financials, healthcare, and defensives, mechanically amplifying the outflow.

Probability-weighted scenarios

• Consolidation then rebound (50%): the correction is healthy. Q2 earnings for the Mag-7 (late July) will be the decisive catalyst. JPMorgan aligns with this scenario. Rebound target for the Nasdaq-100: return to highs if AI margins hold.
• Prolonged correction (35%): if Fed’s Warsh sends an even more hawkish signal at the July 31 FOMC, the Nasdaq remains under pressure. A second downward leg possible, down -15% from the peak.
• Sectoral crash (15%): disappointment in Q2 results + geopolitical escalation (Taiwan, export controls) → an additional -20% on the Nasdaq-100.

Portfolio implications

Reduce implicit duration: lighten tech stocks with P/E > 30x. Strengthen European value (P/E ~12x, dividend yield ~3.5%) and US financials, which structurally benefit from high rates. ETFs XLF (financials) and XLV (healthcare) capture the rotation. Maintain a cash buffer to seize the tech rebound post-Q2 earnings. Stop-losses below the Nasdaq-100’s technical supports (~18,500) reduce drawdown risk.

Risks & blind spots

The value rotation could become self-reinforcing: if momentum funds exit en masse, forced sales amplify the correction regardless of fundamentals. A disappointment in AI margins at Meta or Microsoft could durably shift the narrative on the profitability of the AI cycle.
