StockQuakes

StockQuakes is a stocks tool. StockQuakes runs AI screens over 5000+ stocks after each market close and emails subscribers daily index charts, top 10 detail charts and top 100 PDF reports, ranked by its own UP or DOWN change metric.

StockQuakes is a daily stock screening service that runs proprietary AI algorithms across more than 5000 stocks after each market close and emails the results as charts and PDF reports. Rather than asking users to log into a dashboard, it pushes a newsletter to their inbox at the end of every trading day, built around a single proprietary metric the company calls a StockQuake. That metric measures the amount of change in multidimensional stock data. A larger and more notable shift produces a larger StockQuake number, and each one is graded as small, medium, large or huge. Direction is set by the slope of the price between the daily open and the daily close, so every result is labelled UP or DOWN. The free tier delivers only the average index charts: a rolling 10 day average of the top 10 UP names and the same for the top 10 DOWN names. Paid subscribers also receive the daily top 10 symbol charts with their individual values and 100 row PDF table reports listing symbol, company name and StockQuake value. The audience is self-directed retail investors who already do their own research and want a shortlist to start from, not trade signals or portfolio management. Busy users who cannot screen thousands of tickers themselves are the obvious fit. The output is deliberately narrow: it ranks what moved unusually, and the interpretation is left to the reader. Compared with full research terminals or charting platforms, StockQuakes offers almost no depth. There is no interactive screening, no historical backtesting, no fundamental data and no portfolio tracking. It is closer to a curated morning brief than a research tool, and the distribution model through the Substack newsletter platform keeps it simple at the cost of flexibility. The team describes itself as a fintech quant group with AI and machine learning expertise, positioned around the DYOR investor who wants unusual movement surfaced quickly.
