i2 Technologies, which provides supply-chain management software, closed at 126, up 26.56.
The shares have jumped 48 percent since Tuesday, when the stock closed at 85. Five months ago the shares were trading at about 30.
Although the company did not issue any announcements today, one analyst speculated that investors attending the annual Credit Suisse First Boston technical conference were pleased with the company's presentation. The conference was held Tuesday in Arizona.
In August, i2 Technologies announced a deal with IBM to collaborate on the strategy, marketing and development of supply-chain software and products.
Chris Desautelle, an analyst with Legg Mason, noted the company is in a growth market and has been expanding into new markets. He noted that Wall Street may begin viewing it as an e-commerce company, which carries higher valuations.
"If that's the case, this stock has a long ways to go," he said.
Company officials were not available for comment.
