Every method that could be solved backwards opens on the assumption today’s price makes, so the top range sits on the price — that is arithmetic, not a view. Change any input and it becomes yours.

We don’t tell you what CTM is worth. Every tab OPENS on what today’s price implies for that method’s key assumption; you decide whether that assumption is reasonable — the growth matrix has CTM’s filed history and the AI chat will reason it through with you — and the range you build is yours. Our presets are filed history and reference settings, never a recommendation.
