FBC WatchList

The buy list as a working tool: valuation, traffic light, thesis and log in one file — with a test bench that recalculates every version against the Excel template.

What the WatchList is for

The article Six steps to your own buy list describes the process. The WatchList is the tool for steps 3, 5 and 6 (the full rating from step 4 stays in the Freebird Rating): from the recorded metrics it calculates points, fair value, buy price and crash limit, shows a traffic light for each stock and the gate it is currently stuck at — and records why I bought or deliberately did not buy. Decisions follow rules that are fixed in advance, not the price chart of the day.

WatchList cockpit with key figures, warning signal and buy candidates
Cockpit. What needs doing today: positions with a warning signal, stocks in the buy zone with the next step, status proposals.
Stock list with traffic lights, points, buy price and bottleneck
Stock list. Traffic light, points out of 55, buy price, distance and the bottleneck — the first gate that is not yet open.
Stock file with seven gates, valuation chain and sensitivity
Stock file. Seven gates, the valuation chain step by step and a sensitivity check: does the light flip at 0.5 points higher rates?
Investment thesis with log and break criteria
Thesis. Three sentences, two to four measurable break criteria, review with the next quarterly report. No thesis, no buy signal.
Test bench with twelve test profiles, all identical to the Excel template
Test bench. Twelve test profiles for the special rules against the target values of the Excel template, plus 180 unit tests of the app logic.

The screenshots show the app's practice mode in German with fictitious sample stocks („Beispiel Truck AG (fiktiv)“ etc.) and rounded model values. No real stocks, no own positions and no price targets are shown.

Rules

Seven gates to a buy signal

Every stock passes the same checks in a fixed order. The first gate that is not open is the bottleneck — it is shown next to each stock in the list and tells me what to do next.

  1. Knock-out
  2. Quality
  3. Block
  4. Data
  5. Yield
  6. Price
  7. Thesis

The valuation chain

The buy price comes from a few traceable steps. The points come from the quick test of the Freebird Rating, the fair value follows the fair value calculator — same formulas, same thresholds.

FigureRule
Earnings per shareprice ÷ blended P/E on the day of recording, then fixed
Growththe lower of 5-year earnings growth and the 3-year forecast
Fair P/E100 ÷ (rate + 2.5 points), at most 15; from 15 % growth P/E equals growth, adjusted to the rate and at most 20
Limitfair value − 15 % margin of safety; top stocks from 83 % of points without margin
Yield pricedividend per share ÷ 3 %
Buy pricethe lower of limit and yield price
Crash limitfair value − 30 %

Why an app and not just a spreadsheet

ComponentWhat it does
JournalEvery purchase, deliberate pass, status change and sale with a reason — the basis for measuring my own hit rate later
TasksDerived from the holdings (review due, break criterion triggered, data older than 100 days) and gone as soon as the cause is resolved
Parameter versionsEvery rule change becomes a new version, with a preview of which traffic lights flip
Test benchOn the first start of every new version, all test profiles run against the Excel template, plus all unit tests
Data statesEvery state carries a SHA-256 checksum; damaged states are detected, restoring creates a new state
LocalOne HTML file; data stay in the browser or in a chosen folder. Prices and the reference rate come via my own access to Twelve Data and FRED

I enter the fundamentals by hand from the services I use anyway. They are not passed on — which is why the app is only shown in practice mode.

Demonstration on request The WatchList is a private working tool and not publicly available. I am happy to show it in practice mode: d.krause@freebirdcapital.org.
This page describes a private tool for information and education. It is not investment advice and not a recommendation to buy or sell any security. Traffic lights and buy prices are the output of a rule set, not forecasts.
