What is happening?

On 21st January we were expecting the market to go South. We were right. Again, investors are starting to feel preocupied. For the moment, there is no need. What we are suffering (unless shortsellers) is absolutely normal. As we see on the graph (click above to enhance) the fall is just a minor retracement from the previous maximum.

The oscillator has suddenly decreased its value and it´s targeting to the oversold zone accordingly.
