Tesla chief executive Elon Musk took to Twitter early Friday to defend his peculiar behavior on an earnings conference call that caused shares of the electric car maker to lose more than 5 percent.

"The 'dry' questions were not asked by investors, but rather by two sell-side analysts who were trying to justify their Tesla short thesis," Musk tweeted. "They are actually on the opposite side of investors. HyperChange represented actual investors, so I switched to them."
