Frankfurt's DAX closed about 0.4% firmer at 23,611 on Tuesday, reversing yesterday's decrease, as traders assessed a batch of economic data from major economies while awaiting clues on the Fed’s next policy moves from a speech by Chair Jerome Powell due later in the day. Data revealed accelerated private sector activity in Germany for September, alongside stronger growth in the Eurozone service sector. Market sentiment was also supported by upbeat sentiment following news of the Nvidia–OpenAI partnership.
