Trump Media & Technology Group, trading under the ticker DJT, experienced a pre-market plunge of 5.12% on Thursday, extending its recent losses. The sharp decline comes in the wake of two significant developments: President Donald Trump's announcement of fresh global tariffs on imported goods and the company's recent SEC filing.

The tariff announcement has sparked broader market concerns, with S&P 500 futures dropping 3%. Additionally, Trump Media filed with the Securities and Exchange Commission on Wednesday to allow a trust headed by Trump to sell $2.15 billion worth of stock, although the company stated it has no immediate plans to do so. This filing has raised investor concerns about potential dilution and insider selling.

Trump Media, which operates the social media platform Truth Social, has been struggling financially since going public in March last year. The stock has seen a significant decline from its post-election levels, when it traded around $40. As a proxy for Trump's political fortunes, the stock's performance has been volatile, reflecting both political and business uncertainties surrounding the company.
