Returnstream

Educational website (Returnstream LLC, returnstream.com) selling rule-based market-timing strategies via paid ebooks and backtest spreadsheets. Self-description: helping the “investing public learn that it’s possible to beat the stock market indexes over the long term through active market timing and stock picking.”

Relevance as a source

• Business model: teasers with equity curves + headline stats; full rule sets and spreadsheets are paywalled. Treat published numbers as vendor marketing — verify independently before trusting.
• Strategy family covered here: gold-spx-switching-strategy (momentum rotation). Compare quantified-strategies, which publishes the same strategy family with fully-disclosed rules for free (gold-spx-rs-ratio-rotation).
• Other strategies advertised on the site (not yet ingested): Relative Strength Strategy, Weekly Reversion Strategy, Gold Market Neutral Strategy, Soybean Oil Calendar Spread, Fidelity sector mutual funds vs ETFs comparison.

Source-quality notes

• gold-spx-switching-outperforms-both-assets numbers come from their own backtest; no data source, costs, or engine disclosed.
• Articles are otherwise well-illustrated with long-horizon (1975+) charts.
