SHOW IH: Backtest for EU investors on your portfolio

We just launched Backtest (https://backtest.curvo.eu) which is a free tool for any European index investor who wants to gain more insight into his portfolio.

• You can back-test your portfolio. We have the official historical data for a lot of the popular ETFs and Backtest can run an analysis on the past performance of your portfolio. For example, take a look at the performance since 1981 of Lars Kroijer's Rational portfolio.
• Share your portfolio. Want to show someone your portfolio? Just send them the link! No sign-up or login is required. All the information about the portfolio is embedded in the link. 0 Compare different allocations of the same portfolio. How would your return change if you added more weight to the fixed-income portion of your portfolio? You can answer these questions with the comparator on Backtest. See for example a comparison of three allocations of the same portfolio.
• Share a comparison. Do you want to show off how your portfolio is so much better than someone else's? Just send them the link to the comparison!

Would love some feedback and general thoughts on our tool.

Thanks IH!
