Cisco Systems and Qualcomm, two of last year's highest flyers, issue earnings figures this week but they will have to compete for investors' attention with the Fed and economic data from Washington. Cisco, a bellwether for the internet industry, is today expected to report that earnings plunged to two cents a share, from 18 cents a year earlier. Cisco, last year one of America's top two companies by market capitalisation, does not make the top tier now. The shares are off more than 70% in the past year.
