Comparing JAT to A2M, it really doesn't matter how they sell infant milk. The numbers speak for themselves.

A2M's A$7.6Bn market cap - FY 2020 revenue of A$670m at margins of 27%.
JAT A$28m market cap - forecast to do A$100m in revenues at margins of 32.5% in FY 2021

All that matters is revenue and margins.
I'll break it down and make it obvious.

A2M is valued at A$1.07bn per A$100m in revenues at margins 27%. A2M sales slowing, margin declining
JAT is valued at A$28m per A$100m in revenues at margins 32.5%. JAT sales increasing, margin increasing

Can you see a discrepancy here?
A2M is valued at 38 times higher than JAT per $100M of earnings.

I'm guessing your argument is A2M has market share and can command a price premium. I'd point out that JAT's sales grew 111% last quarter and they are going to be the only ASX listed company with a retail outlet in Shanghai.

It is not pumping to point out a stock is so grossly undervalued. I look forward to any reasonable counter argument as to why today's movement was a pump and not fundamentally warranted.
