On Monday you have the options expiration and you're going to see very high volume. After that, my guess is it's going to be flat. I don't see any direction in the short term.
The day started well, but later all those rumors about important people involved in a scandal caused a lot of nervousness. Many people had been already prepared to sell after recent highs and the ball rolled.
In the United States, there's the question of technology companies' earnings that is complicating matters. The market is highly volatile, with options expiration, oil prices falling. It's a combination of many things.
