According to FactSet, the S&P 500 surged 9.6% in the second quarter through June 30, while the Nasdaq Composite gained roughly 12%. The Philadelphia Semiconductor Index jumped 94%, marking its second-strongest quarterly performance since 1994. Strong earnings revisions drove gains, with S&P 500 second-quarter profit growth expectations reaching 23.1% year-over-year.
Despite the rally, investors now worry about pullback catalysts in the third quarter. Key concerns include portfolio rebalancing at quarter-end, uncertainty around Federal Reserve policy under new Chair Kevin Warsh, and elevated market leverage. High-risk leveraged semiconductor ETFs like SOXL saw assets under management nearly double to $34 billion by late June. According to strategists, options trading volume surged and margin balances increased sharply, with some analysts warning these derivatives could amplify market volatility. Multiple analysts forecast potential corrections of 5-20% ahead.
