Monday's After-Hours Movers Led By Du Pont, Arena Pharma, Illumina & Container Store Group

Shares of Container Store Group Inc TCS are down roughly 4 percent on Monday’s after-hours trading following the announcement of the company’s second quarter financial results.

The small-cap specialty retailer reported earnings of $0.06 per share on revenue of $195.48 million, well below the Street’s consensus estimate of $0.14 per share and $210.13 million.

The biggest loser since the bell rang is, however, Illumina, Inc. ILMN, which is down approximately 15 percent after the company filed an 8K with the SEC, disclosing its estimated revenue for the third quarter of the year, ended September 27, 2015. Although the company estimates revenue will surge 14 percent year-over-year, investors do not seem happy with the other details revealed in the document.

On the other hand, one of the largest gainers in the afternoon is E I Du Pont De Nemours And Co DD, up more than 5 percent since the market closed. The spike was preceded by two pieces of news -- although none of both seem particularly good: long-time CEO Ellen Kullman is stepping down from her position at the end of next week, and management trimmed its full-year outlook. Until the company finds a new CEO, Board Member Edward Breen will fill the position.

The other big winner of the evening is Arena Pharmaceuticals, Inc. ARNA, up about 7 percent in after-hours trading, after having gained 8.59 percent during the day. Once again, the surge was prompted by the resignation of the company’s CEO, President and co-Founder Jack Lief. Harry Hixson will serve as interim CEO until the company finds a permanent replacement for Lief.
