The share price of Trump Media soared by more than 12% in afternoon trading Monday, continuing a stunning rise that began in mid-April.

The DJT ticker was up more than $5 per share just before 1 p.m. ET.

Trump Media owns the Truth Social app frequently used by the company’s majority shareholder, former President Donald Trump, who is also the presumptive Republican presidential nominee this year.

“TRUTH SOCIAL IS THE REAL VOICE OF AMERICA!!!” Trump wrote in a post on the site earlier Monday.

The company began public trading on March 26 with a price of more than $70 per share. Over the next several weeks, share prices cratered, ending up with a low closing price of $22.80 on April 16.

Since then, Trump Media shares have more than doubled in price, adding billions of dollars to the company’s market capitalization, and to the ex-president’s stake.

The gains have occurred without any significant news about the company’s bottom line improving.
