The New York Stock Exchange stopped trading in Longtop Financial Technologies’ (LFT.NYSE) American depositary receipts on Tuesday, citing “news pending” as the reason for the halt, the Wall Street Journal reported. Longtop, similar to a dozen or more recently halted Chinese stocks, has been fighting accusations of fraud and mismanagement. Investors – who have more than US$1 billion tied up in the software company’s ADRs – are concerned that Longtop is the latest and most significant in a string of prolonged halts of Chinese stocks that trade on US exchanges. The case is more disconcerting because the company demonstrates features that US investors often seek; Its auditor is the China member firm of accounting giant Deloitte, and Longtop had a successful initial public offering in 2007.
