Rosen Law Firm said it is investigating potential civil securities claims on behalf of investors in BlackRock, Inc. mutual funds. The investigation concerns allegations that BlackRock may have issued materially misleading business information to the investing public. Investors who purchased the funds may be entitled to compensation without paying out-of-pocket fees or costs under a contingency-fee arrangement, while the firm prepares a prospective class action seeking recovery of investor losses. Investors can join through Rosen Law Firm's website or contact Phillip Kim, Esq. by phone or email. The firm also highlighted its securities litigation practice, past rankings and recoveries, and stated that prior results do not guarantee a similar outcome.
