Shares of PacificNet ( PACT) were among technology's winners Monday, rising 14% after the company posted a big jump in first-quarter results.

The information technology services company earned $415,000, or 4 cents a share, on sales of $9.1 million. Earnings came in at the top end of the company's guidance, and sales were better than the $8.5 million to $9 million that PacificNet had forecast.

According to Thomson First Call, the one-analyst estimate called for earnings of 3 cents a share on sales of $8.5 million. A year ago, the company earned $141,000, or 2 cents a share, on sales of $3.5 million. Looking ahead, PacificNet forecast second-quarter earnings of $550,000 to $700,000, or 5 cents to 6 cents a share, on sales of $10.5 million to $12 million. That's in line with the one-analyst earnings forecast of 6 cents a share on sales of $10.5 million. Shares traded up $1.04 to $8.49.

Simclar ( SIMC) fell 23.8% after the company disappointed investors with its first-quarter results. The electronics contract manufacturer posted earnings of $293,000, or 5 cents a share, on sales of $12.4 million. A year ago the company earned $481,000, or 7 cents a share, on sales of $12 million. In the most recent period, Simclar said it experienced gross margin pressures in one business sector and a loss in one of its manufacturing facilities. The company expects the facility to return to profitability during the third quarter. Inefficiencies associated with the start-up of a new facility also hurt first-quarter results. Shares traded down $1.18 to $3.77.

Shares of InfoSpace ( INSP) rose 3.6% after the company announced plans to repurchase up to $100 million of its stock.

XM Satellite Radio ( XMSR) rose 0.2% after the company said it surpassed the 4 million-subscriber mark. XM Satellite said it added its most recent 1 million subscribers in less than five months. It took the company 23 months to reach its first 1 million subscribers, eight months to reach the 2 million mark and six months to reach 3 million. The company reiterated its year-end goal of 5.5 million subscribers. Shares traded up 6 cents to $28.32.

Shares of Hyperion ( HYSL) rose 0.2% after the company announced a $125 million stock-repurchase plan.
