The Los Angeles Business Journal’s index of largest local public companies closed down slightly as the broader markets lost ground as well.

The weighted LABJ Stock Index fell less than 1 percent to 162.35 for the trading week ended Aug. 30. Decliners outpaced gainers 118 to 40, with six companies unchanged.

Among the biggest decliners was legal newspaper publisher Daily Journal Corp. in downtown Los Angeles. Shares fell 8 percent to $124.39 after the company reported that its profit narrowed in the most recent quarter compared with the same period a year ago.

Also falling was Beverly Hills 3-D technology firm RealD Inc. Shares fell 7 percent to $8.19 amid summer box office that didn’t yield many hits for 3-D films.

Among the biggest gainers was Response Genetics. Shares of the Boyle Heights diagnostic testing firm jumped 20 percent to $2.25 as the company acquired a cancer test.

Also gaining was Broadway Financial Corp., which rose 11 percent to $1 after the L.A. bank holding company announced a recapitalization.
