In the last few weeks, three Tesla board members and a company executive have offloaded more than $100 million in stock, ABC News reports. Board member James Murdoch was the latest to do so, selling about $13 million worth of stock on March 10, a day when the stock dropped more than any day in five years. Tesla stock has been tumbling precipitously since CEO Elon Musk started further dividing his attention away from his private-sector leadership roles with the Department of Government Efficiency, and is down nearly 4% premarket.
