The court should not dismiss the complaint unless it is clear the plaintiff can prove no set of facts that would entitle it to relief. Conley v. Gibson, 355 U.S. 41, 45-46, 78 S.Ct. 99, 101-02, 2 L.Ed.2d 80 (1957). In Count I of its complaint, Caremark alleges that Coram violated Rule 10b-5, promulgated under § 10(b) of the 1934 Act, by failing to disclose the Lineare negotiations. See 15 U.S.C. § 78j(b) (1981); 17 C.F.R. § 240.10b-5. The parties do not dispute that to state a claim under Rule 10b-5, Caremark must allege “loss causation,” in addition to “transaction causation.” See Bastian v. Petren Resources Corp., 892 F.2d 680, 683-86 (7th Cir.), cert. denied, 496 U.S. 906, 110 S.Ct. 2590, 110 L.Ed.2d 270 (1990) (<HOLDING>). See also Pommer v. Medtest Corp., 961 F.2d
