How many points did Dow plunge?

It’s a rough start on Wall Street, unfortunately, this morning.(6)Just after the opening bell, the Dow plunged 150 points, and the view hasn’t gotten much better from there. Investors are reacting to disappointing reports on jobless claims and the US trade deficit. And the number of homeowners filing for foreclosure has hit its lowest point in three years. Good news, right?(7)But some of last month’s falloff may be due to a new banking rule that’s slowing the flow of paperwork, of all things.
