NEW YORK ( TheStreet) -- Shares of Smith Micro Software ( SMSI) slumped in late trades on Tuesday after the company posted a wider than anticipated loss for its fiscal second quarter and gave a weak revenue outlook. The Aliso Viejo, Calif.-based developer of mobile connectivity and communications applications reported a non-GAAP loss of $5.2 million, or 15 cents a share, for the three months ended June 30 with revenue coming in at $16.1 million, well below a year-ago total of $31.4 million. The average estimate of analysts polled by Thomson Reuters was for a loss of 11 cents a share in the June period on revenue of $17.8 million. Smith Micro sees revenue ranging from $15 million to $20 million for its current fiscal third quarter ending in September. Wall Street's consensus view sits at $23.4 million. The stock was last quoted at $2.96, down 11.1%, on volume of less than 20,000, according to Nasdaq.com. Based on Tuesday's regular session close at $3.33, the shares were already off nearly 80% so far in 2011, and sentiment on Wall Street was poor with 10 of the 13 analysts covering the stock rating it a hold.
