European equity markets opened lower on Tuesday, extending the downturn that gripped US technology stocks and the Nasdaq on Monday.

The broad-based correction reflects growing caution among investors as they digest a heavy calendar of macroeconomic data, specifically a series of Purchasing Managers' Index (PMI) releases scheduled for the day.

The sell-off in US tech giants has rippled across borders, weighing on sentiment in Frankfurt, London, and Paris.

Traders are positioning for potential volatility as the PMI data will provide the latest snapshot of global economic momentum.

Any signs of further deceleration in manufacturing or services could reinforce fears of a slowing growth trajectory, particularly given recent softening trends in key emerging markets.
