4 times EV/EBITDA is cheap only when EBITDA will sustain there. I don’t think it will.
About the rising demand due to electric vehicle - I can’t buy a stock in hope that some technology will come and create huge demand for some industry. I am not a venture capitalist. And even if you want to bet on electric vehicles then you should be looking at tyre companies - If the demand rise because of replacement of old vehicles then it will be a tailwind if not then the business will grow at the same speed.
