US markets closed with fairly sharp gains, thus achieving the 4th positive consecutive week. The reasons for the positive trend are several. The main reason for this last rally will be due to the perception that the risks of the US economy into recession are minimal. After an early uncertain year marked not only by the turbulence of the financial markets and the slowdown of the economy, economic indicators for February showed a very dynamic activity. The latest and most striking evidence was the employment report, released on 4 March that signaled a very dynamic labor market, with the economy approaching full employment. The second reason is due to the resilience of oil price, which recovered about 35% from the minimum of the year. Another factor that has contributed to the Wall Street rally is the need for many institutional investors to monitor the rise in their benchmarks. Furthermore, last week for the first time this year, subscriptions of equity funds were greater than redemptions, which provides more liquidity to fund managers apply to the equity market. Perhaps the only catalyst which is confined only to the Friday session was the reversal of the sense of European investors to the decisions of the ECB. Because of the change of time in the US, trading in the US stock market will start today at 13h30 and will end at 20h00 (GMT). Only on 28 March US markets will resume to normal trading hours (14h30-21h00 GMT).
