About Fundsaurus
Our Mission
I created Fundsaurus to provide a risk management tool for ETF investors. Other tools exist out there but are either expensive, difficult to use, often contain errors and the providers are always trying to sell some other investment related product.
Why Fundsaurus?
The world’s stock markets have never been more concentrated in the hands of a very small number of corporations. Most funds are therefore investing in similar or related companies. It’s never been more important to understand how much exposure you have to each company.
- Maintain balanced portfolios
- Reduce volatility through diversification
Our Technology
Fundsaurus uses carefully sourced data and performs all calculations on-the-fly. This means we can calculate your holdings against any benchmark at a low cost since we don’t store that information - and therefore don’t have to pay for storing the results - once your session ends.
