Regulators in the US have halted stock of a company from trading, after its shares surged 36,000%.

Cynk Technology reportedly only has one recorded employee and only a few dollars of assets.

The mysterious stock ran from a few cents to over US$21 (€15) in a month. This gave the firm a market value of over US$6 billion (€4.4 bn).

Cynk - which is headquartered in Belize City, Belize - supposedly operates a social network which Bloomberg says appears to have no members, no revenue and no assets.

The stoppage was ordered by the the US Securities and Exchange Commission (SEC).

The SEC says it has "temporarily suspended trading in the securities of CYNK because of concerns regarding the accuracy and adequacy of information in the marketplace and potentially manipulative transactions in CYNK's common stock".

Reports say the suspension order will last until midnight on July 24th.
