The small-cap sector strayed in and out of positive territory Tuesday before surging late in the trading day, but among the big losers was apparel maker Oxford Industries ( OXM). Shares plunged 21.2% to $28.55 after the Atlanta-based company said its continuing-operations income slid 57.2% year over year to $4.8 million, or 27 cents a share, in the quarter ended Aug. 31. Sales were off 16.2% to $237.9 million. Analysts polled by Thomson Financial had sought 46 cents a share, minus extraordinary items, on a top line of $247.3 million. The Children's Place ( PLCE), a children's clothing retailer, said its fiscal third-quarter EPS should be at least 60% under the 94-cent low end of prior guidance -- that is, some 38 cents or below, including a 7-cent charge for severance payments to former CEO Ezra Dabah. Analysts are looking for 97 cents a share before special items. Fourth-quarter and full-year earnings should also come in "significantly below" prior expectations. The Secaucus, N.J., outfit blamed too-high inventory levels paired with poor revenue trends -- including about a 3% drop in September same-store sales -- which forced "a substantial amount of unplanned markdowns." Children's Place stock surrendered $1.52, or 6.3%, to $22.80. On the other hand, China Sunergy ( CSUN) shot up 24.6% after the solar-power semiconductor concern inked a deal to supply around 106 metric tons of solar-grade multicrystalline polysilicon to Luoyang Zhonggui High-tech, a polysilicon maker, in 2007 and 2008. Financial terms weren't disclosed. Shares of the China-based company climbed $2.48 to $12.56.
