Trump Media extends rally to 280% as MSG event spurs meme-stock activity

• Donald Trump's media firm rose as much as 22% after the presidential hopeful hosted an event at MSG.
• Trump Media is now up roughly 280% from its September low.

Donald Trump's high-profile event at the Madison Square Garden was followed by a surge in his media stock.

Shares of Trump Media & Technology Group — the parent company of Truth Social — soared as much as 22%on Monday, after the former president brought his campaign to Manhattan the day before. Trump's social media firm is now up roughly 280% from a low reached on Sept. 23. It's now trading at its highest level since June.

Other Trump-affiliated meme stocks — or equities popular with the retail-investor crowd that don't necessarily trade on fundamentals — also got a boost on Monday. Rumble, a conservative video network, rose 12% at intraday highs. Meanwhile, Phunware, a software firm that worked on Trump's 2020 campaign, rose as much as 15%.

Sunday's rally at the Madison Square Garden drew a large crowd and featured several key speakers, including Elon Musk. The event kicked off the final stretch of Trump's campaign before November's election day.

Though some speakers drew condemnation for making inflammatory remarks, it had no bearing on Truth Social's share activity. In recent weeks, Trump Media has surged on rising sentiment that the Republican candidate could retake the White House.

Ever since the firm went public in March, investors have treated it as a proxy for Trump's election chances, putting aside the firm's paltry fundamentals.

In this context, the company's five-week rally overturns a downturn that had persisted since the summer. Despite its difficulty in turning a meaningful profit, Trump Media now carries a market cap of more than $9 billion.
