Strong results from chipmaker Intel, which triggered a rally in the entire semiconductor industry, as well as hopes that the U.S. and Iran would return to the negotiating table, pushed the stock market to new all-time highs. The S&amp;P 500 and Nasdaq Composite indexes ended trading on April 24 at record levels, but the Dow Jones, which is called an indicator of the "old" economy, remained in the red zone. Intel shares were excluded from the DJIA in 2024.

On Thursday, the S&amp;P 500 index renewed its intraday historic high, but ended the day in the negative due to news from the Middle East: the publication Axios reported that Iran continued to mine the Strait of Hormuz. Earlier, the US President <a href="https://oninvest.com/article/tramp-porucil-unictozat-suda-razbrasyvausie-miny-v-ormuzskom-prolive-akcii-upali">instructed</a> the Navy to open fire on boats planting mines. This led to a rise in the price of oil. The market was also pulled down by the shares of software developers after the reports of several companies.

U.S. stocks fell, while the price of oil jumped more than 5% in trading on Tuesday, April 21. Hopes that the U.S. and Iran would reach a peace deal before the ceasefire expires on Wednesday are dissipating. Talks that were supposed to take place in Pakistan have stalled, according to media reports, with Iranian officials refusing to participate and US Vice President J.D. Vance postponing a planned trip.

The main indexes of American shares only slightly decreased at the end of trading on Monday, April 20, and oil prices rose significantly. Tensions between the U.S. and Iran intensified over the weekend, but traders are betting that the two countries will eventually reach a compromise, CNBC reported. U.S. President Donald Trump said he is unlikely to extend the truce with Tehran, which ends Wednesday, if a peace deal with Tehran is not reached and emphasized that the U.S. will continue to block the Strait of Hormuz until an agreement is signed.

The S&amp;P 500, Nasdaq Composite and Russel 2000 indexes hit new records on Friday after Iran declared the Strait of Hormuz "fully open" to commercial shipping and U.S. President Donald Trump said Tehran also agreed to suspend its nuclear program. Oil prices collapsed despite the U.S. military maintaining a blockade of Iranian ports and Iranian media saying passage through the strait will remain closed to "unfriendly countries."

The price of Brent crude oil was virtually unchanged, while the dollar's series of declines reached its highest since 2011.
