Trump Media alerts Nasdaq to potential market manipulation from 'naked' short selling of DJT stock

Trump Media has warned the CEO of the Nasdaq Stock Market of 'potential market manipulation' of the company's stock by "naked" short selling of shares.

The warning came as Trump Media has offered shareholders detailed instructions on how to avoid someone loaning out their DJT shares to short sellers, who then execute trades betting that the price of the stock will fall.

Trump Media disclosed the warning to Nasdaq CEO Adena Friedman in a filing Friday morning with the Securities and Exchange Commission.

DJT's share price has rallied in recent days, but is still sharply lower than the more than $70 per share it debuted with on March 26. Former President Donald Trump owns nearly 60% of Trump Media shares. The paper value of his stake has dropped by billions of dollars since DJT began public trading last month.

Trump Media CEO Devin Nunes in his letter to Friedman did not directly accuse anyone in particular of naked short selling, which is the sale of stocks without first having borrowed such sales for that purpose.

But Nunes noted that as of Wednesday "DJT appears on Nasdaq's 'Reg SHO threshold list,' which is indicative of unlawful trading activity."

"This is particularly troubling given that 'naked' short selling often entails sophisticated market participants profiting at the expense of retail investors," Nunes said.

Nunes, whose company owns the Truth Social app, pointed to circumstantial evidence, which included DJT being in early April the most expensive stock to short in the United States, which he said would give brokers "significant financial incentive to lend non-existent shares." The letter links to a CNBC article detailing the sky-high premiums brokers were charging short sellers for loans of DJT shares to sell.

"I write to bring your attention to potential market manipulation of the stock of Trump Media & Technology Group Corp." Nunes wrote.

"As you know, 'naked' short selling — selling shares of a stock without first borrowing the shares of stock deemed difficult to locate — is generally illegal pursuant to Securities and Exchange Commission ('SEC') Regulation SHO," he wrote.

"Data made available to us indicate that just four market participants have been responsible for over 60% of the extraordinary volume of DJT shares traded: Citadel Securities, VIRTU Americas, G1 Execution Services, and Jane Street Capital," Nunes wrote.

"In light of the foregoing, and Nasdaq's obligation and commitment to protect the interests of retail investors, please advise what steps you can take to foster transparency and compliance by ensuring market makers are adhering to Reg SHO, requiring brokers to disclose their 'Net Short" positions, and preventing the lending of shares that do not exist," Nunes wrote.

"TMTG looks forward to assisting your efforts."

A Nasdaq spokesperson told CNBC, "Nasdaq is committed to the principles of liquidity, transparency, and integrity in all our markets."

"We have long been an advocate of transparency in short selling and have been an active supporter of the SEC's rules and enforcement efforts designed to monitor and prohibit naked short selling," the spokesperson said.

A spokesman for Virtu Financial, the parent company of Virtu Americas, declined to comment.

CNBC has also requested comment from Citadel Securities, G1 Execution Services, and Jane Street Capital.

Data from Factset shows that the short volume in DJT shares has not significantly changed since April 7, while the stock price has sharply dropped before seeing a pointed bounce in recent days.

Short volume is the number of tradable shares being sold short during a specific period.

The data suggests that there was no change in the pattern of short selling that affected DJT's price during that same time.

Trump, the presumptive Republican presidential nominee, currently is on trial in New York state court on criminal charges related to a 2016 hush money payment by his then-lawyer to the porn actor Stormy Daniels.
