This week was marked by a great hesitation before the US markets finally decide to opt for the rise.

The week was marked by two major events, the first being the ratification by D.Trump protectionist measures on aluminum and steel that will ultimately affect mainly Europe and China, in the background of resignation of the chief economic adviser of President, Gary Kohn, Tax Plan Architect and supporter of free trade.

This week was marked by a new fall that led the Stoxx600NR to fall by 3.67% and the S & P500 which fell by more than 2% following D.Trump's decision to tax imports of aluminum and steel, which risks provoking a trade war with China and the main trading partners of the US, Europe in particular.

After the fall, then the rebound, this week was marked by the hesitation that led the Stoxx600NR to increase by 0.23% and the S & P500 finally increased by 0.55% after a session of sharp rise on Friday (+1,6%), which followed a FED report that did not seem to be concerned about the slippage in inflation.

After the last week sharp correction, this week was marked by a marked rebound, more extensive on the US indices (+ 4.3% for the S & P) than on the European indices (+ 3.3%) which is due to for two main reasons, the first being EURO / USD, which has fallen back above 1.25, penalizing the European industrial sector.

Very strong correction on the equity and commodities markets this week, with an unusual fall of nearly 6% on the US indices (S & P500) and 5% for the Stoxx600NR. This is due to US 10-year yields, which remain above 2.8%, in the wake of US unemployment statistics for the month of January, which shows signs of inflation on wages.
