European stock markets were set to open on a positive note on Tuesday, with intentions to recover the losses incurred in the previous session, as investors' risk appetite appeared to stabilize. The regional markets were expected to mirror Wall Street's overnight rally, driven by significant gains in major tech companies following reports of Nvidia's potential investment in OpenAI. Market participants were also anticipating the preliminary September PMI figures for the Eurozone, Germany, France, and the UK, seeking fresh economic insights. In early trading, futures for the Euro Stoxx 50 rose by 0.2%, and Stoxx 600 futures increased by 0.1%.
