There was fighting between Israel and Iran. Because of this, oil became more expensive, and company shares went down on Friday. People are worried that there might not be enough oil for everyone, and the economy could have problems. Big companies lost money, but oil companies in America made more money. People are watching to see what happens next. The price of oil went up a lot. Some companies that use a lot of fuel, like cruise ships and airlines, lost money. But companies that make oil, defense companies, and gold went up. Prices are mostly okay, but some people worry about new taxes from President Trump.
