Public companies based in the greater San Fernando Valley region saw their stock price drop as the Dow Jones fell by just more than 3 percent, or 800 points, and the Nasdaq fell by 3 percent, or 242 points. Pharmaceutical company Amgen Inc., (AMGN), in Thousand Oaks, closed down $5.80, or nearly 3 percent, to $198.87, while Burbank entertainment and media giant Walt Disney Co.
