Shares of Tesla Inc. tanked 6.0% in premarket trading Tuesday, which puts them on track to open about 24% below their record close. Many on Wall Street define a bear market as a decline of 20% or more on a closing basis from a significant peak. If Tesla’s stock closes below $706.47, which is 20% below the Jan. 26 record close of $883.09, the bear market would become official. The last time the stock entered a bear market was Sept. 8, 2020, when it closed at $330.21, or 33.7% below the then-record close of $498.32 on Aug. 31. The stock rose to a new record on Nov. 19. Tesla’s stock has still run up 36.9% over the past three months through Monday, while the S&P 500 has gained 8.4%.
