RE:VFF VS HEXOWhen comparing companies within the same sector I would suggest getting to know what the Price to Sales Ratio is. It is essentially a way to see what investors are paying per share vs the sales being brought in by the company on a per share basis
There are drawbacks to the comparison (as with any 1 to 1 comparison) such as debt load carried and it does not take into account future developments of a company such as increases in production, new (expected) partnerships and access to new markets (Europe and US eventual legalization).
Regardless, here are the comparisons for the stocks you refered to
