Crypto hoarding brings a stock pop for small firms—and in some cases shows patterns of possible insider trading

In mid-July, the stock for the cancer drug developer MEI Pharma skyrocketed. It wasn’t because the small company, first listed on the Nasdaq in 2003, had discovered a blockbuster cancer cure. Rather, MEI Pharma’s soaring share price coincided with the company’s decision to buy up $100 million of the cryptocurrency Litecoin for its treasury.

The pop in price, which saw shares go from $3 to a high of $7, wasn’t surprising. In announcing the Litecoin purchase, MEI Pharma became just the latest firm to exploit a popular stock price hack: When a public company adds crypto to its balance sheet, traders have responded by buying up shares and boosting the firm’s value well beyond the cost of the purchase.

What was unexpected, however, was that MEI Pharma’s stock price almost doubled in the days before the announcement became public—despite there being no material updates filed with the Securities and Exchange Commission, no press releases, and barely any chatter on social media.

MEI Pharma is not the only firm that has recently experienced an unusual pop in its stock right before announcing a crypto-buying strategy. Fortune discovered a similar pattern at other small public companies, which suggests that insiders are front-running some of these announcements, according to finance professors, investors, and corporate CEOs.

“It does look suspicious to me,” said Xu Jiang, a professor at Duke University who has studied insider trading in public markets. “This usually happens for a lot of insider trading scenarios that I anecdotally know about.” He added that he couldn’t say whether insider trading definitively occurred without a thorough investigation.

A spokesperson for MEI Pharma declined to comment.

Spokespeople for four other companies whose stock showed unusual price movements just prior to crypto purchases—Kindly MD, Empery Digital, Fundamental Global, and 180 Life Sciences Corp—did not respond to a request for comment. Spokespeople for VivoPower and Sonnet BioTherapeutics, two other crypto treasury companies with similar price movements, declined to comment.

Crypto treasury boom

Treasury companies are one of crypto’s newest manias, and billionaire Michael Saylor is the trend’s pioneer.

In 2020, the founder and chairman of Strategy, formerly called MicroStrategy, announced that his data analytics software company would add Bitcoin to its balance sheet. Traders saw the company’s stock as a proxy for the world’s largest cryptocurrency, and bought up its shares as the price for the world’s largest cryptocurrency increased.

For Strategy, the tactic proved so successful that it went on to accumulate almost $70 billion worth of the cryptocurrency and reached a market capitalization of around $100 billion, despite reporting only a paltry $115 million in revenue in the second quarter of this year. (By comparison, Starbucks , which has a similar market capitalization, reported $7.8 billion in revenue in the same period.)
