Among the companies with shares expected to actively trade in Thursday's session are Conn's Inc. (CONN), Francesca's Holdings Corp. (FRAN) and Aeropostale Inc. (ARO).

Conn's fiscal third-quarter earnings soared as the retailer reported broad sales growth, again led by furniture and mattress sales. The company raised its per-share earnings estimate for the year and issued a profit forecast for the upcoming year that topped analysts' expectations. Shares rose 15% to $67.40 premarket.

Francesca's fiscal third-quarter earnings fell 20% as same-store sales decline amid weak demand for apparel tops and jewelry. The retailer said the holiday selling season is off to a weak start and lowered its outlook for the fiscal year, sending shares down 12% to $16.00 premarket.

Aeropostale swung to a fiscal third-quarter loss as the youth-focused apparel retailer continued to struggle with falling sales and teens' lackluster response to new style offerings. Shares fell 6% to $8.80 premarket as the company guided for a wider-than-expected fiscal fourth-quarter loss and the latest period's results missed the company's and Wall Street's expectations.

Korn/Ferry International's (KFY) fiscal second-quarter profit surged due in large part to a big revenue boost in the company's leadership and talent consulting business, as well as a favorable comparison to the year-ago period. Shares rose 5.3% to $23.70 premarket as the company's earnings beat its expectations.

S&P Dow Jones Indices said General Growth Properties Inc. (GGP) will join the S&P 500 index, replacing Molex Inc. (MOLX), a move that sent the real-estate investment trusts' shares 4.3% higher to $21.15 premarket.
