Elon Musk sued for late disclosure of his Twitter stake
A Twitter shareholder is suing Elon Musk for not disclosing his stake in the company. Marc Bain Rasella filed the suit alleging that Musk had violated securities law by not disclosing his 5% stake in TWTR as per regulation. The Tesla CEO had accumulated this stake by 14 March (blue vertical) which required a public disclosure not more than ten days later, 24 March (green vertical). Instead, Musk only disclosed his position on 4 April (black vertical), by which time he had acquired more than 9% of the social media company.
According to Rasella, this lack of disclosure allowed Musk to accumulate TWTR stock at a relatively low price. However, once Musk filed the position, TWTR 's price jumped 27% to $49.97, implying that investors who sold before had been disadvantaged by the late disclosure.
