U.S. stocks added roughly $400 billion in market value at Friday’s open after unconfirmed reports said Qatar was helping broker a U.S.-Iran peace deal in Tehran, prompting investors to buy risk assets. The newer topic says Al Arabiya later retracted the peace-deal report after the headline was followed by a rise in stocks and a drop in oil prices. Together, the reports show how unverified geopolitical news can rapidly shift market sentiment across equities and commodities, while the underlying agreement itself remained unconfirmed.
