Continuing its strong Wall Street performance, Smith Micro Software Inc.'s stock rose 57% on Wednesday after the Aliso Viejo-based company unveiled a new program that allows Apple computer owners to make telephone calls over the Internet.
Smith Micro also announced Macintosh software for building online stores.
The shares moved up $1.81 to $5 in trading of 1.9 million shares, more than four times the average daily volume over the last three months.
The company's stock rocketed to $6.50 from $1.75 over two days in December, a bullish response by investors to Smith Micro's entry into the electronic-commerce arena in September, the launch of its Linux product in November and its strong position in the Macintosh segment.
