Earnings season begins to unravel as mobile-phone maker

Motorola

(MOT)

issues its first-quarter results today.

Wall Street anticipates that Motorola's announcement will set the tone for the entire tech sector since its products and services are distributed across a wide range of industries. According to the 24 analysts polled by research firm

Thomson Financial/First Call

, the Illinois-based company is expected to post a loss of 7 cents a share, as compared to a profit of 20 cents a share a year ago.

Ahead of earnings,

Morgan Stanley Dean Witter

raised its rating on Motorola to a strong buy citing the company's strong valuation. Shares of Motorola were trading at $11.50 at yesterday's close, as compared to $49.48 just a year ago.
