You mean single order suffers more loss in value than vertical spread order due to vega? (I'm still struggling to understand all the implications of Greeks in various option set-ups.)
I read what went down and it seemed he didn't care to answer most of the questions that were thrown at him...he ignored most of them...I'm actually surprised tsla isn't down even further this morning.... shareholders aren't liking that conference call one bit
not quite. Vega goes both ways. you can make or lose on it. Some traders trade it exclusively. Read up on the greeks-delta , gamma, vega, theta before trading. Options are complex and trader have many "vectors" to make $$. They can choose to expose their position to theta or gamma, or vega or delta-ie direction. Depends where you think u can be good at. The trading unicorns are good at more than 1 ( I ain't one of them). In your situation, if you want to make a directional bet on XYZ, then try to minimize the other greeks so verticalizing hedges your vega-somewhat.
