The U.S. Securities and Exchange Commission said Friday that it has temporarily suspended the trading of three companies as it looks into statements they made regarding the purchase of cryptocurrency and blockchain-related assets.

The regulator announced that the trade of securities for the companies – Cherubim Investments, Inc., PDX Partners, Inc., and Victura Construction Group, Inc. – will be suspended between 9:30 a.m. EST Friday and March 2. The suspension notice was dated Feb. 15.

The agency explained:

A release published by the agency cites additional reasons for the suspensions. In the case of Cherubim, the trading halt came as a result of "its delinquency in filing annual and quarterly reports."

The suspensions represent the latest move by the agency to halt trading of companies that have publicly stated some kind of pivot or business focus on the technology. In at least one case, the public suspension followed a significant run-up in the price of a stock in light of those remarks.

In August, the agency issued a warning to investors about the risk of pump-and-dump schemes that use statements about initial coin offerings (ICOs) in order to drive market action.

"Fraudsters often try to use the lure of new and emerging technologies to convince potential victims to invest their money in scams," the SEC said at the time.
