Economic calendar: German ZEW, Palantir earnings

• European markets expected to open lower after US tech sell-off

• German ZEW index seen little change in May

• Palantir to report earnings before Wall Street session open

European index futures point to a lower opening of today's cash session on the Old Continent. Given that economic calendar for today lacks any top tier readings, investors will focus on price action and whether yesterday's sell-off extends onto the coming days. German ZEW is a key reading scheduled for today but it rarely results in a major market reaction. When it comes to earnings, investors will be offered reports from Palantir and Electronic Arts, among others.
