European stock index futures fell more than 1% on Friday, tracking declines in Asian and U.S. equity markets on caution around a retail trading frenzy that gripped Wall Street this week.

Futures tracking an index of Europe’s top 50 stocks were down 1.2% by 0647 GMT, setting up the benchmark STOXX 600 index to retreat further from near one-year highs hit last week.

London’s blue-chip index futures dropped 1.1% and Germany’s DAX futures declined 1.2%, while on Wall Street, S&P 500 futures fell 1% and Nasdaq 100 futures shed 1.1%.
