A day before he sold Tesla shares, musk called on tens of millions of fans on Twitter to vote informally to help them decide whether to sell about 10% of Tesla shares. Twitter data showed that about 3519252 people replied, of which 57.9% voted in favour. This led to a sharp drop in Tesla's share price. The SEC declined to comment < p > Tesla filing documents show that jinbar sold 88500 Tesla shares worth about $109 million the day before his brother launched the twitter vote < p > the insider trading act of the United States stipulates that employees and board members of the company cannot conduct transactions based on information that has not been made public. But under the so-called "10b5-1 rule", employees and board members can avoid insider trading charges by trading at a predetermined time. Jinbar has used this method in the past and has made 40 transactions under this rule since 2011. However, the stock sale information on November 5 showed that jinbar did not seem to rely on the rule < p > securities law experts believe that regulators may investigate whether musk told his brother about his twitter vote or stock sale before jinbar sold his shares on November 5, or whether jinbar knew about the vote and traded in advance < p > in response to the relevant survey, musk said by email: "kimbar didn't know I was going to launch a poll on twitter." He also claimed that Tesla's lawyers knew he would vote. However, this statement has aroused doubts. It is not sure whether musk informed Tesla's lawyer about the voting, which was required by his settlement with the sec < p > musk also said: "when I vote on Twitter and my stock sales revenue is reduced by more than $1 billion, I will care whether my brother will sell shares for millions less. This idea is ridiculous." < p > since late October 2021, Tesla's share price has been rising due to the strong performance in the third quarter of 2021 and the good news that Hertz, a car rental company, announced that it would order 100000 Tesla cars < p > although some fans believe that they voted in the twitter poll to provide suggestions for Musk's stock sales plan, in fact, the Tesla CEO said as early as September 2021 that he might sell "a large number" of Tesla stock options in the fourth quarter. He also said he had to sell a large part of his shares to pay the tax bill. Most of Musk's internal transactions are sold in accordance with the "10b5-1 rule", which is part of the transaction plan formulated on September 14, 2021 < p > Musk's relationship with the SEC has deteriorated since he was accused of securities fraud by the SEC in 2018. Tesla, musk and the SEC finally reached a settlement agreement in 2019 to resolve these allegations. As part of the agreement, musk shall not serve as chairman of Tesla for three years, and he cannot be convicted in the settlement agreement < p > Musk's relationship with the SEC has become more tense in recent weeks. He accused the SEC of letting him and Tesla accept "endless and groundless investigations". These investigations amounted to harassment and retaliation for his public criticism of federal financial regulators. He also claimed that the SEC was divulging information about the federal investigation, but did not provide any specific evidence to support this claim. (small) < / P > < p >
