The Los Angeles Business Journal’s index of the 200 largest local public companies closed down for the week ended Jan. 29 as investors worried that strong gross domestic product growth in the fourth quarter couldn’t be sustained.

The weighted LABJ index dropped 3 percent to 110.12, with decliners outpacing gainers 125 to 50.

Several small bank shares took a hit for the week. Saehan Bancorp, a struggling Koreatown bank that earlier in the week had soared on news of a prospective capital infusion, pulled back late in the week and closed down 32 percent to $1.05.

Hanmi Financial Corp., which also had jumped on media reports that an investor was ready to commit a substantial amount of capital to the Koreatown bank, fell 22 percent to $1.99.

Avery Dennison Corp. fell 16 percent to $32.51, with most of the loss coming after the Pasadena office supplies maker reported fourth-quarter profit that failed to meet Wall Street expectations.

OSI Systems Inc. lost 9 percent to $26.47 after a Morgan Keegan analysts downgraded shares of the Hawthorne security and medical scanning equipment maker from “outperform” to “market perform.”

Among the gainers was the new Live Nation Entertainment Inc., which gained nearly 25 percent to close at $11.47 after the merger of Beverly Hills’ Live Nation Inc. and West Hollywood’s Ticketmaster Entertainment Inc. closed their merger after reaching agreements with U.S. and Canadian anti-trust regulators.

Wilshire Bancorp Inc. was among the few significant financial gainers for the week, closing up 8 percent after reporting fourth quarter net income that was better than analysts expected.

Calabasas home builder Ryland Group Inc. rose 6 percent to $22.26 after reporting that it had turned to a profit in its fourth quarter despite fewer sales, primarily due to higher gross margins and some earlier cost cutting.
