Investors were expecting a bad jobs report, but not so bad that there was no job growth in the U.S. The atrocious news sent global shares tumbling. The Hang Seng Index in Hong Kong closed down more than 370 points, or 1.8 percent. In Japan, the Nikkei also fell 1.2 percent to 8950. The Dax in Germany and the CAC in Paris both plunged more than 3 percent by the afternoon. Global stocks, like their U.S. counterparts, had been up for a few sessions, with the Nikkei having gained for six straight days before Friday, but concerns about the U.S. economic forecast looked to end the week on a low note.
