The acquisition of the social media company by Musk sent the stock price of the electric car maker on a roller coaster. The investors seem to be unaffected by the drama.

Back in April, when Musk first announced his intention to acquireTwitter, it was just weeks after the price of the company's stock hit a peak. Since then, it has declined fairly consistently and opened today at $139.34 a share, a 64.5% haircut from this year's high.

Wall Street analysts wrote down the investment due to predictions that Musk will sell more shares to keep the company solvent.

While all this drama is going on, one of Musk's other companies is largely unaffected.
