- Tuesday saw a decline in both European stocks and US market index futures as investors braced themselves for significant earnings announcements from a number of well-known tech companies.

- US equities futures dropped after the tech-heavy Nasdaq 100 had its largest two-day surge since November as traders braced for the worst tech earnings collapse since 2016. Earnings were expected to challenge the year-to-date risk rally. The Stoxx 600 index for Europe's area lost an early gain and turned negative.

- Although better than anticipated, the latest business activity statistics indicated persistent weakness in the euro union and in Britain, and later that day, US figures will provide investors with a glimpse of how the greatest economy in the world is doing.

- However, the impending wave of US corporate profits from tech behemoths like Microsoft and Texas instruments as well as industrials like GE is going to take centre stage.
