Last month, shares of the electric carmaker Tesla jumped after its CEO posted a mysterious
"Really exciting @TeslaMotors announcement coming on Thursday. Am going to put my money where my mouth is in v major way," Elon Musk said.
Shares increased to $38.40 shortly after the post and closed up 2.4 percent to $37.51.
The announcement, delayed until April 2, involved a financing plan in which consumers could lease a luxury Tesla S for an "effective monthly cost" of $500 a month.
