Elon Musk's Twitter musings have always moved Tesla's shares, with the infamous "funding secured" tweet drawing the ire of authorities.
Here is a brief timeline tracing Musk's candid Twitter posts that have impacted the market.
April 1, 2018: An April Fools' joke that fell flat, Musk's tweet that Tesla has gone "completely and totally bankrupt" came following a run of bad news for the automaker, including production shortfalls, regulatory scrutiny over its driver-assistance system Autopilot and a credit rating downgrade further into junk by Moody's Investors Service. All that combined to send the stock down as much as 8.1%.
Aug. 7, 2018: Shares closed up nearly 11% after Musk tweeted during market hours: "Am considering taking Tesla private at $420. Funding secured."
May 1, 2020: Tesla erased around $13 billion from its market value after Musk tweeted "Tesla stock price is too high."
Nov. 6, 2021: Elon Musk proposed selling 10% of his stock on Twitter, and took a poll of people on the social network to see if they supported it. After a clear majority (58%) of 3.5 million Twitter users voted yes, Tesla shares tumbled the most in eight months, falling as much as 7.3% as of Nov.8.
Mooers, what do you think of Musk's tweets? Have his tweets influenced your trading decisions?
