Thanks to HBO’s documentary, “The Inventor: Out for Blood in Silicon Valley,” and a barrage of media coverage about Elizabeth Holmes and her defunct company, Theranos, it is unmistakable that big misrepresentations can lie in public statements regarding miniscule quantities of blood.

This lesson proved true again last month, when the CEO of Decision Diagnostics, a pharmaceutical testing company, widely publicized that the company could accurately test for COVID-19, providing near-instant results with only a finger-prick of blood. In one press release, the CEO, Keith Berman, went so far as to say the COVID-19 testing would be “commercial ready” by summer of 2020.  The market took note, and the company’s stock soared (by a whopping 1,200%) following Berman’s statements.

COVID-related securities claims continue to rattle the marketplace. On December 7, a leading plaintiffs firm announced an investigation on behalf of shareholders of The Cheesecake Factory Inc., just days after the SEC announced it was settling charges against the company for making misleading disclosures about the impact of the COVID-19 pandemic on its business operations and financial condition. The SEC’s action was its first charging a public company for actions tied to the worldwide pandemic.
