Dow falls 390 points

The Dow Jones industrial index crashed through its post-terror attack low today in a dramatic 390-point selloff after news of a US government investigation at Johnson & Johnson gave already uneasy investors another reason to pull back.

It was the average’s seventh biggest point drop yet, and its lowest close in nearly eight years. Analysts attributed the declines to Wall Street’s unwillingness to make any bets in a market that appears capable of only falling farther.
