AlphaScreener is for DIY investors researching US stocks and testing fundamental or technical strategies. Its screener applies more than 80 filters across over 15 categories to help narrow a universe of more than 6,000 stocks and rank candidates against your criteria. Use Evaluate to backtest a screening strategy against more than 20 years of historical data. Results include portfolio statistics, comparisons with the S&P 500, performance across past market stress periods, and base rates that show how often simulated portfolios beat the benchmark across different starting dates and holding periods. The tool is designed to account for look-ahead and survivorship bias, but backtests are hypothetical and do not predict future results. You can also create watchlists, view interactive graphs, and explore individual stocks’ historical data, fundamentals, earnings, and peer comparisons. A Market tab provides an S&P 500 heat map, sector performance, major US index trends, and market movers. AlphaScreener may suit investors who want to screen and evaluate stock-picking ideas; it is a research tool, not a trading service.
