(Bloomberg) -- Tesla Inc. wiped roughly $126 billion off its valuation Tuesday as the stock fell 12% on investors’ concern that Elon Musk may sell shares to complete his $44 billion takeover of Twitter Inc. The electric-vehicle maker’s market capitalization is now down more than $275 billion since April 4, when Musk disclosed that he increased his Twitter stake. That’s a drop of roughly 23%. The dollar value of Musk’s 17% stake in Tesla has shrunk by more than $40 billion, almost double the equity portion he pledged in the Twitter transaction.
