Growth produces accounting profit

Insufficient evidence: Unavailable

Reported-period net margin. A positive figure supports accounting profitability, not cash generation. · Company financial statements · date unavailable

The business generates cash after investment

Insufficient evidence: Unavailable

Latest reported free cash flow. It is not a forecast and it is not the fiscal-year snapshot. · Company financial statements · date unavailable

These are explicit tests of individual claims, not an overall bull/bear rating. Demand growth can coexist with valuation, concentration and financing risk.
