How it works
Four steps. You write the first two. The last two happen every night, on their own.
Find a company
Open any company we cover and read its ratios, computed from the accounts it filed. Every figure opens into its formula, its inputs, and, where one stands behind it, the statement they were read from and the date it was filed. A figure that cannot show that trail says so.
Write down why you own it
Your reasoning in your own words, and beside it the numbers that have to stay true for it to hold. We propose each line from that company’s own current figures; you set the level.
We check it every night
New filings land, the figures are recomputed, and the numbers you wrote down are tested again against them, wherever we hold the figure. The check runs every night at 23:30 UTC. A filing is picked up the night after it is published. You can read how many passes have finished and what each guardrail read at the last two.
You hear the day a reason breaks
One email, the first night our data shows the break, naming the figure, the level you set and the statement it was read from. Silence otherwise, and it never fires twice for the same break.
What arrives
One email, the night a line breaks.

ExampleThesis assumption breached: operating margin
7h agoYou assumed operating margin stays at or above 12%. Last night's check read 10.90% from the FY2025 statements filed Feb 19, 2026. Fires once, then silent while the breach persists.
Recovered: return on invested capital back above 20%
Jun 3Quiet note, no email. Re-armed for the next breach.
