Among the many tumbling small-cap stocks Thursday was

G-III Apparel

(GIII) - Get Report

, which lost 15.7% to $17.46 on disappointing guidance.

The New York outerwear maker reported a narrower-than-expected loss of 42 cents a share for the quarter ended April 30, but it also predicted a wider-than-expected loss in the next quarter -- between 19 and 24 cents a share, or at least 7 cents under Thomson Financial's analyst estimates. Full-year earnings should also come in lower than anticipated.

Meritage Homes

(MTH) - Get Report

was likewise sliding on soft guidance. The Scottsdale, Ariz., home-construction company said preliminary sales for the first two months of the second quarter plunged about 21% from a year ago. Cancellation rates on gross orders climbed by 9 percentage points year over year to 36%. Shares sank 5% to $31.46.

Meanwhile, Atlanta-based

Spectrum Brands

( SPC), maker of batteries and other products, fell 5.5% to $7.57 on word its chief financial officer, Randall Steward, has resigned. Anthony Genito will replace him.

Spectrum, along with Meritage, helped to pull down both the Russell 2000 and the S&P SmallCap 600. Each was recently off at least 1.8% to underperform the major indices.

On the flip side,

Viewpoint

( VWPT) jumped 13.2% to $1.20 after the New York-based Internet marketing company regained compliance with the

Nasdaq

, having maintained a minimum share price of $1 for at least 10 consecutive business days.

Russell 2000 member

PriceSmart

(PSMT) - Get Report

bounced 8.5% to $22 after the San Diego discount retailer said same-store sales surged 21.3% in May, with total revenue gaining 21.7% on last year to $72.5 million.

Finally,

ICU Medical

(ICUI) - Get Report

added 2.8% to $41.33 in heavier-than-usual trading after the Food and Drug Administration approved its Genie device. The closed vial access product protects health-care workers from the dangerous effects of working with chemotherapy drugs.
