Build low-risk portfolios by defining how much you can lose
What it does
This tool helps investors build low-risk portfolios by starting from downside risk instead of expected returns. You define your investment amount, time horizon, and maximum acceptable loss. The app calculates how much capital must be allocated to safe assets (using current bond yield curves) and how much can be allocated to risk without exceeding that limit. It’s scenario-based, not predictive, and focused on capital preservation.

I built this after realizing my index fund owned companies I'd never choose to support, and there was no easy way to do anything about it. Sylph lets you specify what you want to avoid (and what you want to support), then generates a diversified portfolio of individual stocks based on your priorities. Working demo, no account needed — just try it. Still early and actively building, so feedback is very welcome.

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it.

Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
