Shares in troubled database company Sybase Inc continued downwards yesterday following the company’s disclosure that fourth quarter revenue would be in the region of $245m to $250m compared with analysts’ estimates of around $264m. The stock closed down $0.75 at $9.18, not much above its 52-week low. The company’s per share estimates range between a loss of $0.07 to a profit of $0.02 compared with the average of analysts’ estimates as surveyed by First Call of a profit of $0.07. Morgan Stanley & Co expects Sybase to show a small profit from operations but a loss on a per share basis because of foreign exchange. The revenue shortfall, it says, was down to the North American market. Europe was strong and Asia Pacific as expected, the bank reports.
