One thing I have noticed over the last seven years trading penny stocks is that penny stock scammers are quick to hop on any current investment theme. If oil is spiking, we will see a lot of shell companies quickly turn into oil exploration companies. If there is a spike in the price of rare earth elements, we will see a new crop of rare earth miners. Recently with the Ebola panic we had a bunch of penny stocks touting their connection to the disease. And the SEC was quick to act to suspend trading in some of the most egregious Ebola stocks.
See the chart of Lakeland Industries (LAKE) below to get a sense for the timeline over which the Ebola hype played out (LAKE is shown as it was one of the Ebola stocks that spiked the most; is a real company and was not implicated in anything):
The peak of Ebola panic occurred around the 13th of October 2014. Just over a month later, on November 20th, the SEC suspended trading in four purported Ebola-related penny stocks. The four stocks that were suspended by the SEC were Bravo Enterprises Ltd. (OGNG), Immunotech Laboratories, Inc. (IMMB), Myriad Interactive Media, Inc. (MYRY), and Wholehealth Products, Inc. (GWPC).
