Trump Media and Technology Group, better known by its ticker DJT, is held by a disproportionate number of retail investors, who seem to buy or sell depending on the political winds.
The stock shed nearly $400 million in market value today as Trump's performance was perceived, generally, unfavorably.
In comparison, the stock soared more than 30% on the Monday following an attempted assassination of Trump in July, which analysts suggested at the time could make a second term more likely.
Between the lines: "Trump Media has said its business hinges at least partly on Trump's popularity, and analysts say the company's value will rise or fall based on his electoral prospects," CNBC noted today.
