Despite ex-president's claim of winning debate, Trump Media shares hit new post-merger low.

• On Thursday, Trump Media's stock price dropped by 3.6%, reaching a low of $16.07 per share, which was the lowest close since the company's debut on the Nasdaq in March.
• The stock price of Trump Media, represented by the ticker "DJT," has decreased by approximately 14% since the first presidential debate on Tuesday night in Philadelphia between Donald Trump and Kamala Harris.
• Trump declared on Thursday that he would not participate in another debate through a post on Truth Social, his personal social media platform.

On Thursday, shares of continued to decline, reaching a new low, after the presidential debate between its majority shareholder, former President Donald Trump and Democratic Vice President Kamala Harris on Tuesday.

Since its public trading debut on the Nasdaq in March, the stock has not closed at a lower price than $16.07 per share, despite falling 3.6% over the day.

The stock price of Truth Social, owned by Donald Trump, has decreased by approximately 14% since the Tuesday night debate in Philadelphia, hosted by ABC News.

The Harris campaign and pundits and strategists on both sides of the political spectrum have declared Tuesday's debate a victory for the Democrat, while Trump has consistently stated that he emerged triumphant in the encounter.

The slide in Trump Media shares suggests that investors are not convinced that Trump won the debate.

The Republican nominee declared in a Thursday afternoon post on Truth Social that he would not participate in another debate.

Trump, claiming victory, wrote "THERE WILL BE NO THIRD DEBATE!" after Harris challenged him to a second round moments after the candidates left the stage Tuesday night.

The latest chapter in the stock's months-long slide is DJT's plunge this week.

Since the failed assassination attempt on Trump in July, shares of Trump Media have fallen approximately 60%. Additionally, since merging with a special purpose acquisition company and going public in March, the stock has experienced a decline of about 78%.

Nearly 57% of Trump Media's stock is owned by the former president. In the near future, he will be able to sell his stake when the "lock-up" restrictions are lifted. It is uncertain whether he will decide to sell or retain his shares.

The company's market capitalization was $3.2 billion after Thursday's close.
