A positive post on President Trump's Truth Social site can increase stocks, particularly in the oil and stock markets, particularly during the Iran war. This sentiment was seen again on Tuesday amid concerns that the U.S. and Iran would not negotiate a resolution. After the market close, Trump announced that he would extend the ceasefire until Iran came up with a unified proposal. The oil market has been extremely volatile throughout the war, trading sharply lower or higher depending on the administration's statements. Goldman Sachs CEO David Solomon made a reference to this phenomenon in an interview with CBS' Kelly O'Grady.
