S&P 500 futures just took a plunge, European equity futures follow suit

Eurostoxx futures are now down 1.0% as the cash equity market is set to open in just about 2 minutes.

If this continues, this is going to weigh on risk sentiment and give the yen a little boost later on in the day as well.

The only thing I can point to is concerns on the trade rhetoric. Apart from that, there isn't much to go on as there isn't any headlines or news that is causing a stir in the market at the moment. US stocks made a U-turn overnight so European traders are likely having their say in the matter now.
