Studies and criteria from the quant literature, legendary investors and their letters, IBD, the seasonals and the flow signals. Search by source, strategy, or type. Each entry carries testable criteria. Entries marked with a star run here; the rest are read-only for now. Run one, change the criteria, run it again.
Everything here is documented research or a documented rule of thumb, not a promise. A study's result in one market and period may not repeat. Runs use price-only index history (no dividends, taxes or slippage beyond the cost you set), cash earns nothing, and rules are tested on the same history that inspired many of them, so treat a good run as a question to ask, not an answer. Not investment advice.
