The Dow Jones Industrial Average (DJINDICES:^DJI) has gained just one point in pre-market trading, suggesting a flat start to the stock market today. Still, there are plenty of earnings results on tap that could drive big swings in individual stocks.

Netflix (NASDAQ:NFLX), for example, will book its quarterly results right after the closing bell today. Analysts expect the streaming video company to log a 25% sales boost and report as many as 4 million new streaming subscribers. And yet the stock is down by roughly 30% since March. Netflix bears and bulls can't both be right, so expect to see the stock swing in one direction or the other this afternoon.

Meanwhile, Hasbro (NASDAQ:HAS) and Halliburton (NYSE:HAL) stocks are already on the move this morning, after the companies posted quarterly earnings results of their own.

Hasbro booked a profit for its fiscal first quarter, reversing the small loss it suffered a year ago. The toy and games maker saw quarterly revenue tick higher by 2% to $680 million, while earnings came in at $0.24 a share. My Little Pony products made the difference, spurring a 21% boost in business for the girls segment and offsetting flat results in the rest of the company. Hasbro's first-quarter results look solid, especially considering that Easter fell outside the quarter this year. Investors also continue to get plenty of cash rewards for holding this stock, as the company paid out $52 million in dividends and spent $80 million on share repurchases throughout the quarter. The stock was unchanged in pre-market trading.

Halliburton said this morning its first-quarter earnings grew to $0.73 a share from last year's $0.67 haul. Sales crept higher as well, to $7.3 billion, which made it a record first quarter for the energy products and services giant. Those top and bottom-line results were also slightly ahead of Wall Street's estimates. The best news for Halliburton investors, though, looks to be the company's results in its North American division. That unit logged a 5% revenue boost despite the extreme winter weather. Halliburton said it expects that business to grow even faster for the rest of the year, pulling profit up with it: Margins in the North American business should hit 20% by the end of the year, according to the company. Halliburton's stock was up 0.8% in pre-market trading.
