For instance, the spreads in Amazon's (NASDAQ: AMZN) purchase of iRobot (NASDAQ: IRBT) and MaxLinear's (NYSE: MXL) absorption of Silicon Motion (NASDAQ: SIMO) have widened considerably.

SAMR, the Chinese antitrust regulator, asked Silicon Motion and MaxLinear to refile the deal in August, denying their request for expedited review.
