Do you think Porsche$$s strategy of using options to acquire a stake in VW $($instead of buying stocks directly$)$ is a sensible one? Or do you agree with the critics who argued that Porsche was speculating with shareholders$$ money and that it had become a $$hedge fund$$ that neglected its core business? Please argue in adetailed manner for and against. Update: would it have been better to buy shares directly or a merger?
