define: mispriced = "value != market price"
Where you and i diverge is "Value is relative in one case and absolute in the other."
I think you're saying that HF Guy's definition of value is relative and Value Guy's definition of value is absolute.
If its even correct that any company has a single true value, I think this number is unknowable. Investors or traders make estimates of this value, and if their estimate deviates significantly from the market price, they transact with Mr. Market.
Nobody's estimate is more absolute or relative than any one else's.
