I'm close to going against everything I stand for and actually buying shares in a BUSINESS (as opposed to a LIC or index fund). SEV is just so incredibly cheap: I reckon fair value is at least 50% above current price.
Of course it's impossible to say whether this is a "solid support level or the beginning of further downside" but it's got to be a good long-term hold.
I like SEV's big pile of cash and lack of debt.
