Friday's Small-Cap Winners & Losers

One of the most heavily traded small-cap winners in a buoyant Friday session was Crystallex International (KRY Quote).

Shares of the gold miner shot up 17.4% to $3.10 on promising news regarding its ongoing attempts to get construction and development permits for its Las Cristinas project in Venezuela. After holding hearings on the issue earlier this month, according to the company, the chairman of a Venezuelan National Assembly commission "reiterate[d] demands to the Ministry of Environment to grant the corresponding license, thus allowing the mining development to begin."

ScanSource (SCSC Quote) soared 20.2% after sprinting past fiscal first-quarter estimates with a profit of $15 million, or 57 cents a share, excluding penny-a-share costs related to an internal stock-option probe. The Greenville, S.C., specialty tech-products distributor also said revenue totaled $553.7 million. Analysts polled by Thomson Financial sought 48 cents a share on sales of $544.1 million.

Shares were up $6.24 to $37.19, which gave legs to both the Russell 2000 and the S&P SmallCap 600. The sector trackers ramped up 1.9% and 1.8%, respectively.

Sierra Wireless (SWIR Quote), a communications-equipment maker, jumped 13.7% to $21.69 after third-quarter income leapt more than eightfold year over year to 33 cents a share for a 6-cent per-share beat. The Canada-based company also pegged next-quarter earnings at an above-par 35 cents a share.
