Southern California firestorm singes local stocks

Reuters reports that several companies in Southern California have been hit by the firestorm there. The stocks in these companies have fallen less than the market -- the S&P 500 is down 3.2% -- in the last week. But in one case -- Broadcom (NASDAQ: BRCM) -- investors dumped the stock for reasons unrelated to the fire.

These six public companies have been affected by the fires as follows:

• Jack in the Box (NYSE: JBX). The San Diego corporate headquarters were closed on Monday and Tuesday, though spokesman Brian Luscomb said there were a couple of dozen employees working at the fast food company's building on Tuesday morning. Its stock is up 0.1% in the last week.
• Qualcomm (NASDAQ: QCOM). Few showed up at the San Diego headquarters of the wireless technology and semiconductor developer, where the bulk of its 11,200 worldwide employees work. Its stock is down 2.8% in the last week.
• Broadcom (NASDAQ: BRCM). The semiconductor firm closed its San Diego office, but was open in Irvine. Its stock is down 20.9% in the last week -- due to a downgrade.
