Wall Street tech selloff deepens, European shares steady

US equities, particularly the tech-heavy Nasdaq, saw a second consecutive day of significant declines, with the Nasdaq Composite dropping 1.1% and major AI stocks falling over 1%, attributed to valuation concerns, profit-taking, and increasing government scrutiny on the tech sector. Conversely, European shares held steady, with the FTSE 100 hitting a record high. Market focus is now acutely on the Federal Reserve's upcoming Jackson Hole symposium, where Chair Powell's speech on the economic outlook and policy framework will be closely watched for cues on interest rates, as traders are largely pricing in a September rate cut, influencing a slightly weaker dollar and easing Treasury yields.

Analysis

A significant, two-day selloff is impacting the U.S. technology sector, with the Nasdaq Composite declining 1.1% on Wednesday, bringing its two-day loss to approximately 2.5%. The weakness is concentrated in AI-related large-cap stocks, including Nvidia, Broadcom, Meta, Amazon, and Alphabet, which all fell by over 1%. This downturn is attributed to a combination of profit-taking after a period of strong earnings, concerns over elevated valuations, and emerging political risks. Specifically, reports that the U.S. Commerce Department is considering taking equity stakes in chipmakers like Intel, following unconventional revenue-sharing deals with Nvidia and AMD, have introduced uncertainty regarding the institutional framework for the tech industry. In contrast, European markets demonstrated resilience, with the pan-European STOXX 600 rising 0.25% and the UK's FTSE 100 reaching a record high. The broader market's focus is now squarely on the upcoming Jackson Hole symposium, where Federal Reserve Chair Jerome Powell's commentary will be scrutinized for signals on monetary policy. With traders heavily pricing in a September interest rate cut, fueled by recent weak labor data, any hawkish deviation from Powell could disrupt market expectations, which are currently reflected in easing U.S. Treasury yields and a slightly weaker dollar.

Key Decisions for Investors

• Investors should closely monitor exposure to the US technology sector, as the current selloff is driven by both technical profit-taking and a new, material risk of government intervention in companies like Intel, Nvidia, and AMD.
• Positions should be managed with the upcoming Jackson Hole symposium as the primary near-term catalyst; any statement from Fed Chair Powell that contradicts the market's high expectation for a September rate cut could trigger significant volatility across asset classes.
• The noted divergence between the underperforming US tech market and the record-setting UK FTSE 100 suggests that portfolio managers could consider regional diversification to mitigate US-specific political and valuation risks.
• Traders should remain attentive to currency markets, particularly the US dollar and New Zealand dollar, as central bank policy divergence is actively driving performance, evidenced by the RBNZ's rate cut and the Fed's anticipated move.
