Whether an appellate court has authority to consider challenges to issues of law raised in a pre-verdict Federal Rule of Civil Procedure 50(a) motion for judgment as a matter of law if the same challenges are not subsequently renewed in a post-verdict Rule 50(b) motion in the district court

QUESTIONS PRESENTED FOR REVIEW Whether an appellate court has authority to consider challenges to issues of law raised in a pre-verdict Federal Rule of Civil Procedure 50(a) motion for judgment as a matter of law if the same challenges are not subsequently renewed in a post-verdict Rule 50(b) motion in the district court. And if so, whether purported misrepresentations, which do not involve or affect the value or underlying substance of the securities transacted, can support a finding of a violation of the anti-fraud provisions of the securities laws, Section 10(b) of the Securities Exchange Act of 1934 or Section 17(a) of the Securities Act of 1933.
