The first Circuit Court of Appeals decision applying the Supreme Court’s landmark 2014 decision in Halliburton Co. v. Erica P. John Fund Inc., 134 S. Ct. 2398 (2014) (“Halliburton II”), favored the defendants, finding as a matter of law that Best Buy Co. and its executives successfully rebutted the presumption of reliance set forth in Basic v. Levinson, 485 U.S. 224 (1988) at the class certification stage through evidence of a lack of price impact from their alleged misstatements. See IBEW Local 98 Pension Fund et al. v. Best Buy Co., Inc. et al., Case No. 14-3178 (8th Cir. Apr. 12, 2016). By reversing the district court and holding that a class could not be certified, the Eighth Circuit showed that Halliburton II provides defendants with a meaningful opportunity to challenge the fraud on the market presumption. The plaintiffs’ bar, however, will be eager to highlight Best Buy’s unique pattern in trying to limit the impact of the decision beyond this case. Whether other federal courts follow the Eighth Circuit’s lead and deny class certification motions based on Halliburton II in greater numbers, and outside the Best Buy fact pattern, remains to be seen.
