Elon Musk
Elon Musk sounded nervous during Tesla's Tuesday earnings call.
  • On Tuesday, Tesla's stock tumbled after Q2 earnings revealed the EV maker missed expectations again.
  • In the call, Elon Musk faced terse questions about resource allocation and the delayed Robotaxi project.
  • The Tesla CEO sounded defensive at times as he responded — and maybe for good reason.

Tesla on Tuesday had a lackluster earnings report that revealed the electric vehicle maker once again missed investor expectations.

And Elon Musk is probably a little nervous.
