Frankfurt's DAX 40 pared gains to close virtually unchanged at 25,178 on Wednesday, amid cautious optimism about a US-Iran potential deal, amid conflicting signals from both sides. Iranian state media reported details of an unofficial draft peace framework with the US, outlining an end to the US naval blockade and Iran’s commitment to reopen the Strait of Hormuz within 30 days. Energy prices fell even though Washington denied the information. Consumer discretionary stocks were the standout performers. Adidas led gains among stocks, surging 5.3%. Airline Lufthansa advanced 3.3%. Carmakers also advanced strongly, with Mercedes-Benz Group, BMW and Volkswagen adding more than 2% each, buoyed by positive EU monthly car sales data. Top losers included Siemens Energy (-3.9%), RWE (-3.4%) and Fresenius SE & Co (-2.1%).
