Most-quoted passages

The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 46 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.

  1. “[I]t is impossible to accord much significance to the number of market makers, until one knows the volume of shares that they committed to trade, the volume of shares they actually traded, and the prices at which they did so. The economic literature has criticized reliance upon the number of market makers as an indicator of efficiency.”

  2. “If the presumption [of reliance] applies [under a fraud-on-the-market theory], a class action is much easier to maintain because individual proof of reliance is not necessary. In the absence of such a presumption, individual issues are more likely to predominate.”

  3. “the questions of law or fact common to the members of the class predominate over any questions affecting only individual members, and that a class action is superi- or to other available methods for the fair and efficient adjudication of the controversy.”
