CAPM Explainer Where an expected return comes from.
Type a company. The app fits beta to five years of real monthly returns, then builds the expected return piece by piece.
Native app · 0.5 MB · macOS 14+, Apple Silicon and Intel · Spanish and English · signed and notarized by Apple · needs internet for Yahoo Finance · educational, not financial advice · Source on GitHub
Install on your Mac
One click. The installer is signed with an Apple Developer ID and notarized, so macOS opens it without warnings.
- Open the .pkg and click Install
The app goes straight into Applications and opens by itself. Nothing to drag.
- Then: type a company
Write a name or ticker (Inditex, KO, Apple) and press Calculate. The app follows your system language (Spanish or English) and needs internet for Yahoo Finance data.
Or run it from source
git clone https://github.com/nachoie123/capm-explainer cd capm-explainer pip install -r requirements.txt python server.py # then open http://localhost:8000
The app needs its small Python server (it fetches Yahoo data and does the maths), so it can't run as a static page here. There's also a command line: python capm.py KO.
