A group of hedge funds have formed a new lobbying arm to promote the benefits of shareholder activism across the U.S. economy, as U.S. politicians turn up the heat on activist investors. The Council for Investor Rights and Corporate Accountability (CIRCA) announced its formation on Wednesday, saying it is committed to promoting the actions of shareholder activists, and their positive impact on corporate governance and business policies at publicly traded companies. The Washington D.C.-based trade association said it is backed by a consortium of activist firms, but does not name them in the press release.
