The lawsuit, filed on June 16, 2015, alleges that Magna participated in a scheme to manipulate the price of Yippy’s stock. Magna’s “pump and dump” scheme involved the issuance of phony press releases, hypothecation and naked short selling of Yippy’s stock, and attempted corporate bribery, according to the complaint. Granville is suing Magna for fraud and unjust enrichment.
