Check out which companies are making headlines before the bell:
Home Depot — The Dow component reported quarterly earnings of $1.60 per share on revenue of $23.2 billion, both above Wall Street estimates. Same-store sales, a key measure for retail firms, rose 5.5 percent in the third quarter, also beating forecast.
Southwest Airlines, American Airlines, Delta Air Lines, United Continental — Securities and Exchange Commission filings showed Warren Buffett's Berkshire Hathaway has taken a stake in Delta, United Continental, and American. CNBC also learned that Berkshire also took a stake in Southwest. Shares of the four airlines moved higher in premarket trading.
Harley-Davidson — Analysts at RBC Capital Markets upgraded the motorcycle maker's stock to "sector perform" from "underperform" and raised their price target to $57 from $46. "In reevaluating our prior thesis, we were using a lower target multiple to consider some growth risks. But, we believe the potential for growth looks improved, so we now apply historical average multiples," RBC said.
JD.com — China's second-largest e-commerce firm reported third-quarter revenue growth of 38 percent year-over-year and posted fourth-quarter sales guidance that could end a recent trend in slowing growth. The firm's U.S.-listed shares rose more than 7.5 percent before the bell.
Mobileye — The car automation company reported better-than-expected sales and profits for its third quarter, with CEO Ziv Aviram citing a strong performance from its core business. "Strategically, we continue to see rising interest for higher-level autonomous vehicle technology," he said.
Teva Pharmaceutical Industries —The Israeli pharmaceutical company reported mixed quarterly results, beating estimates on the bottom line, while missing on sales. The firm said, however, its revenue grew 15 percent because of a $40.5 billion acquisition of Allergan's generic drug business in August.
FedEx — Analysts at Stifel downgraded the shipping giant's stock to "hold" from "buy," citing challenges from FedEx's acquisition of TNT Express earlier this year. "TNT was not the best-run company and it will take FedEx time and money to upgrade TNT to FedEx standards and integrate it properly into the company's global network," Stifel said.
Dick's Sporting Goods — The sporting goods retailer posted better-than-expected sales and earnings on the back of strong same-store sales. Dick's reported comparable-store sales growth of 5.2 percent, easily beating an estimate of 2.8 percent.
