U.S. stocks rebounded on hopes of diplomatic progress between the United States and Iran and a sharp drop in oil prices. The S&P 500 rose 73.99 points, or 0.98%, to 7,654.06, and the Nasdaq Composite Index rose 332.28 points, or 1.31%, to 25,769.28.

The Nasdaq pars losses as expectations for a U.S.-Iran deal and risk sentiment pick up ahead of the midterm elections

Nasdaq pared some of its losses after a sharp sell-off led by AI and technology stocks, as market expectations for a U.S.-Iran agreement improved risk sentiment. Iran proposed over the weekend that it would reopen the Strait of Hormuz within a two-day framework in exchange for sanctions relief, unfreezing assets and lifting the blockade, but the United States has not yet accepted it.

How the Midterms Could Affect Defense, Healthcare, Crypto and AI Stocks

Meta will open big tech earnings after the U.S. close on Wednesday, with three tests including core business health, AI monetization beyond adoption and real returns on infrastructure spending.

The report stated that Bitcoin is not currently regarded as a portfolio diversification tool because its market correlation is unstable, but it is regarded as a speculative asset and a hedge against monetary easing; the bull market scenario has an annualized return of 16.6%, and the bear market scenario has an annualized loss of 11.2%.

The decline in yields was interpreted as the market's concerns about AI-related credit risks, and attention will be paid to Federal Reserve Warsh's speech at the IMF roundtable.

标普500等权重策略失效，科技股再现疲态，投资者该如何应对集中度风险？

The S&P 500 equal-weighted strategy will continue to underperform the market capitalization-weighted index in 2026, and the high weight of technology stocks will increase concentration risks again. As of now, the equal-weighted index has underperformed for nearly four consecutive years, with a single-month decline of more than 4% in September, the longest losing streak since 2022; technology stocks still account for nearly 40% of the standard index, while only about 16% of the equal-weighted index. Experts recommend not to hold equal-weighted ETFs alone, but to pair market capitalization-weighted ETFs such as VOO and SPYM with weighted products such as RSP and EQL, supplemented by mid-cap stocks, low-tech, low-correlated assets and short-duration investment-grade bonds.
