The Los Angeles Business Journal’s index of largest local public companies closed down for the week ended Feb. 25, as skyrocketing oil prices amid concerns about Middle East instability dampened local stocks.

Manufacturers were down, including Los Angeles metals processor Reliance Steel & Aluminum Co., which fell 3 percent to $55.09.

Los Angeles oil company Occidental Petroleum Corp. which has operations in Libya and elsewhere in the Middle East, was down 2.7 percent to $103.14.

Concerns that higher gas prices would slow consumer spending affected companies such as Monrovia pre-paid debit card provider Green Dot Corp., which fell 3 percent to $53.14.

Among a handful of gainers was Los Angeles nutritional supplement distributor Herbalife Ltd., which rose 9.8 percent after reporting better-than-expected earnings.

El Segundo satellite TV provider DirecTV Group Inc. closed the week up only 1.7 percent to $45.05 despite reporting a fourth quarter profit and announcing that it had attracted more new subscribers during the period than in any previous quarter over the past decade.

Calabasas life sciences staffing company On Assignment Inc., which on Wednesday was up 16 percent on strong earnings and an acquisition announcement, ended the week up just 1.6 percent to $10.48.
