NEW YORK — The Dow Jones industrial average is ending at its lowest level in more than six years. The Dow has hovered around its lows of November since Tuesday when the blue chips tumbled 300 points. The Dow’s finish below the Nov. 20 mark leaves the index its lowest level since Oct. 9, 2002. Worries about the economy and, on Thursday, the strength of the technology industry, weighed on stocks. The Dow is ending down 89.68, or 1.2 percent, at the 7,466 level. The Standard & Poor’s 500 index is down 9 at the 779 level. The technology-heavy Nasdaq composite index fell 25 to 1,443.
