A Texas-based wealth management firm has apologised for a clerical error that gave the appearance it took a massive short position on shares in Donald Trump’s social media company just before Saturday’s assassination attempt. The Securities and Exchange Commission (SEC) filing by Austin Private Wealth dated July 12 showed the firm had shorted 12 million shares in Trump Media & Technology Group Corp (DJT) via a put option, sparking frenzied conspiracy theories after the unusual trade was highlighted by a number of social media users.
