Blue-chip stocks managed slim gains yesterday, but the broad market was mixed again after drifting through a lazy holiday session with no bond trading to motivate investors. On Wall Street, the Dow Jones industrial average rose 6.14 points to 7,558.73.

Broader blue-chip measures also turned higher just before the close, but those indexes dominated by smaller companies and technology issues failed to recover.

Declining issues outnumbered advancers by a 10-to-9 margin on the New York Stock Exchange, with 1,336 up, 1,483 down and 593 unchanged.

NYSE volume totalled 434.60 million shares. The Standard and Poor's 500-stock list rose 2.65 to 923.78, and the NYSE composite index rose 0.79 to 485.66. The Russell 2000 index of smaller companies fell 1.97 to 433.43, the Nasdaq composite index fell 5.86 to 1,584.86, and the American Stock Exchange composite index fell 0.04 to 680.43.
