"Once they were on the call, I should have answered their questions live," Musk said via Twitter. "It was foolish of me to ignore them." Musk's behavior let air out of Tesla stock even during the call, which occurred after the stock market closed but while aftermarket trades still were occurring. Tesla was recovering somewhat Friday, up more than 2.5% to more than $292 at midday. But at that price, it's still down for the year and off more than 24% from its high of $385, reached last September.
