The Los Angeles Business Journal’s index of largest local public companies fell for the week ended June 3 as investors reacted negatively to disappointing jobs and manufacturing reports.

The weighted LABJ index closed down 2 percent to 126.53, with decliners outpacing gainers 114 to 55.

Beverly Hills 3-D cinema technology company RealD Inc. continued to be one of largest decliners on continued concerns about dwindling consumer interest in paying higher ticket prices for 3-D versions of films. Shares fell 17.6 percent to $25.39.

DreamWorks Animation SKG Inc. likewise fell 11 percent to $23.24 on 3-D concerns. Though the 3-D version of the Glendale studio’s “Kung Fu Panda 2” had a relatively strong opening, a smaller percentage of opening weekend revenue came from 3-D screens compared with earlier films.

Manhattan Beach-based Skechers U.S.A. Inc., which has been hurt by slowing sales of its Shape Up toning shoes, lost another 11 percent to close at $16 for the week.

Among the top gainers was Santa Monica medical reprints publisher Derycz Scientific Inc., which gained 8.6 percent to $2.85 after announcing a Japanese partnership and the hiring of a former AstraZeneca executive to oversee global sales.

La Canada sporting goods chain Sport Chalet Inc. rose 6.8 percent to $2.35 after reporting that it had swung to a profit in its fiscal fourth quarter.
