Trump Media stock hits a new low of under $18 since its public trading began.

• Since its debut on the Nasdaq stock exchange in March, Truth Social, a social media platform owned by Donald Trump's parent company, has reached a new public trading low.
• The broader market decline, including the Nasdaq, Dow Jones Industrial Average, and S&P 500, led to a dip in the DJT index on Tuesday.
• After the "lockup agreement" period ends later this month, Donald Trump and other major shareholders will be permitted to sell their shares, although the Republican presidential nominee has not indicated any intention to do so.

The stock price of Trump Media, owned by former President Donald Trump, reached its lowest point since its public trading debut in March due to a merger.

The stock's price dropped to $17.89 per share around midday Tuesday, marking a significant decline from its previous low of $19.38 per share on Aug. 28. The stock is currently down approximately 77% from its high of $79.38 per share on March 26, following the merger of Trump Media with a publicly traded special purpose acquisition company.

On Tuesday, the Nasdaq, Dow Jones Industrial Average, and S&P 500 all experienced a decline, with the Nasdaq leading the way with a 2.7% drop. Trump Media's single-day slide of more than 8% was particularly notable.

The decline in Trump Media's stock price cannot be fully attributed to market trends.

The company's stock is more like a meme stock than a traditional investment and its value fluctuates with the political standing of the Republican presidential candidate.

After Trump survived an assassination attempt in July, the stock spiked, coinciding with a surge of voter support for his presidential bid and several high-profile endorsements.

Trump Media's latest drop is happening weeks before Trump, who owns almost 59% of DJT's outstanding shares, and other company executives can cash in on the falling stock. As of Tuesday, Trump's stake was worth over $2 billion.

If the stock price remains above $12 per share for 20 trading days within the 30-trading-day period that started last Friday, the lockup agreement that prohibits Trump and other major stockholders from selling their shares could expire as early as Sept. 20.

Speculation has swirled that Trump's financial woes, including campaign expenses and lawsuits, could influence his decision to sell.

If Trump decides to take the payday, investors' uncertainty about the company could increase, possibly leading to a broader stock selloff.
