Many reasons makes me think that the scenario on US shares hasn't ended yet. Yellen will start a more tightened for a long period. It may reduces a bit activity and so reduce profit and attraction of US shares. Nonetheless it is just a correction to get a price less overvalued.
On the technical view, we can see that a complex head-and-shoulders pattern is consolidating and shares exchange level is increasing. These big volumes may indicate us that a lot of shares are changing from hands to hands. It's a bigger distribution phase with bad economic anticipations. So we may be careful about the fuel remaining to pump S&P-0.49% .
My first target is on the chart.
Good luck everyone,
