Trump Media and Technology Group (DJT) said Thursday that it had sent a memo to the US Securities and Exchange Commission about the "potential illegal naked short selling and market manipulation" of its stock.

The company said in the letter that the activities of UK-based hedge fund Qube Research & Technologies were "suspicious" as the hedge fund only disclosed a short position of almost 6 million shares in Trump Media in Germany.

Third-party sources also informed Trump Media that the hedge fund's total short interest as of April 16 was around 11 million shares, "virtually unchanged" from 10.7 million shares on March 31, according to the letter.

"We urge you to immediately investigate this suspicious trading and report your findings back to [Trump Media and Technology Group] and any relevant civil and criminal authorities," the company said.

Qube did not immediately reply to a request for comment from MT Newswires.
