Cigna - The health insurer earned $1.52 per share, excluding certain items, for the second quarter, beating consensus by ten cents. Revenue also beat estimates, and Cigna raised its full-year forecast as membership numbers grow.

Knight Capital - The trading firm is expected to detail the impact of yesterday's technology glitch, which resulted in irregular trading in a number of stocks.
