What Would Make You Wrong? Building an Anti-Thesis Into Every Investment Call
A token 'risks' paragraph is not an Anti-Thesis. What separates a defensible bear case from a decorative one — and how a falsifier with a measurable threshold changes an IC meeting.
Why is 'risks' at the end of a memo not enough?
Because it isn't argued. A defensible Anti-Thesis is written by someone who has actually sat across the deal — in banking, in management, in a competitor's seat — and who is compelled by the workflow to argue it as hard as the bull case. Everything else is decoration.
What does a real falsifier look like?
It looks like a number, a date, and a data source: 'if free cash flow conversion is below X% for two consecutive quarters by Q, the thesis is materially wrong.' Not 'macro headwinds may weigh on the sector.'
