SAN FRANCISCO (MarketWatch) -- The U.S. dollar index pared gains Thursday as a drop in jobless claims to their lowest level in four years dulled investor interest in the safe haven currency. The euro also cut its losses against the greenback. The dollar index DXY +0.13% , which tracks the greenback against a basket of six rivals, rose to 79.026, down from an earlier high of 79.20 and up from 78.925 late Wednesday in North American trade. The euro EURUSD -0.11% bought $1.3133, up from a low of $1.3084 but still down from $1.3159 late Wednesday.
