European equity markets were set to open largely unchanged on Wednesday, maintaining recent losses due to concerns over inflated valuations and increasing anticipation that the US Federal Reserve might not cut rates. This sentiment continued to exert pressure on risk assets. Investors were also keenly awaiting Nvidia's eagerly anticipated earnings report for insights into the robustness of the AI sector. In Europe, focus shifted to UK inflation data, which could influence the Bank of England's rate decision in December. In premarket trading, both Euro Stoxx 50 and Stoxx 600 futures remained flat to slightly negative.
