About Barudion
What is Barudion?
Barudion is an adaptive ETF portfolio tool that uses a Bayesian algorithm to dynamically allocate your investments across stocks, bonds, gold, and commodities. It aims to deliver the full return of stocks with about half the risk, based on published scientific research.
Who is it for?
Barudion is for individual investors who want to optimize their ETF holdings without giving up control. It's ideal for those who are comfortable executing trades themselves and want a data-driven strategy. It's not for passive investors who prefer fully automated management.
How it works
Each week, Barudion calculates optimal weights and provides a calculator that tells you exactly which ETFs to buy or sell to rebalance your portfolio. You can choose to update weekly, monthly, or quarterly. You maintain full control of your brokerage account.
Use cases
Investors use Barudion to replicate Ray Dalio's All-Weather Portfolio for free, to track the S&P 500 with lower volatility using the Basic plan, or to aim for higher returns with leveraged ETFs on the Pro plan.
Key features
- Bayesian Algorithm — Published in a peer-reviewed journal, providing a scientific basis for portfolio adjustments.
- Dynamic Allocation — Automatically adjusts between stocks, bonds, gold, and commodities based on market data.
- Model Portfolios — Three strategies: Free (All-Weather), Basic (S&P 500 with half risk), and Pro (leveraged ETFs).
- Transparent Calculator — Tells you exactly how many shares of each ETF to buy or sell.
- Full Control — You execute trades in your own brokerage account; Barudion provides guidance, not automated trading.
- Open Source — Repository on GitHub for full transparency.
