Dow ends wild week on high note

The wildest week in Wall Street history ended with a second day of gains.

The Dow Jones industrial average finished today with a gain of 125 points. Most other times it would have been a fairly big day. By this week’s standards, it was a sleeper. Friday capped a week when the blue-chip index had four 400-point swings in a row for the first time in its 115-year history.
