FAQ
What is JoesanStk?
A quant stock-research tool for A-shares, HK and US markets: multi-factor ranking, reproducible backtests, AI-assisted analysis and paper trading. It is a research tool, not investment advice.
Which markets are covered?
A-shares, Hong Kong and US stocks, with data auto-updated after each market close.

Stocks are scored cross-sectionally across technical, money-flow, quality, growth and valuation dimensions, with each factor's contribution shown transparently.
Are the backtests reproducible?
Backtests use strict point-in-time, forward-adjusted data with no look-ahead bias; same parameters reproduce the same result. Past performance does not indicate future results.
