The day is not over, and things can still happen, but we can still have a look of the US market today. This is what I'm going to do, even if I'm going to shock some people, because I don't agree with the fact Yellen dehydration during the speech is worrying for the market and for the health of the figure of the Federal Reserve (if you wonder, I read that while reading news this morning). The truth is that NASDAQ is driven down by the biotechnology industry who, over the past 12 months, rose of 12%, but fallen of 5.7% today. Meanwhile, Dow Jones is positive (0.5%) today mainly because of the 8.9% increase of Nike Inc, with its good quarterly results, and S&P 500 fell of 0.2%. I don't expect a lot to happen from now to the market's close, however.
