Take a look at some of Thursday's early movers:
Schlumberger—Citi upgraded the oilfield services giant to "buy" on the basis the firm's strategy and ability to deliver will allow the stock to outperform with an approximate annual upside of 15 percent over three years. Citi did lower earnings estimates on lower activity expectations and cut its target price to $87. The stock jumped more than 1 percent in pre-market trade.
Lululemon—Wedbush added the athleticwear firm to its best ideas list, maintaining an "outperform" rating based on continued same-store sales momentum, gross margin expansion extending past 2016 and greater upside to earnings in the second half of 2015. Shares of the firm jumped more than 1 percent in pre-market trade.
eBay—Piper Jaffray upgraded the online auction site to "neutral" from "underweight" to reflect the shareholder impact of the completed PayPal spinoff. Piper said expectations of market share loss and structural limitations to growth are appropriately priced in to eBay's current valuation. The stock gained more than 1.5 percent in pre-market trade.
Joy Global—The mining equipment maker reported a 37 percent decline in quarterly profit due to weak demand. The firm derives about 60 percent of revenue from coal miners. In the third quarter, net income fell to $44.9 million, or 46 cents per share, versus $71.3 million, or 71 cents a share, a year earlier. The stock plunged about 8 percent in pre-market trade.
