DRAUPNIR
Our first engine. A concentrated portfolio of up to 20 S&P 500 stocks, listed trade by trade from its first day; since late July 2026, every trade is confirmed with the broker.
LTQS is an independent research project. Two rule-based engines trade US stocks with real money, in public, losses included.
Our first engine. A concentrated portfolio of up to 20 S&P 500 stocks, listed trade by trade from its first day; since late July 2026, every trade is confirmed with the broker.
Our second engine, built from a different starting point. Live since June 2026 on earlier builds; the current build has run since 27 July 2026, and its record is the one we publish.
Each engine trades its own brokerage account. Returns come from the balance the broker reports each day, trades are listed rebalance by rebalance, and the drawdowns stay in.
Portfolio PerformanceLive recordDRAUPNIR’s live account since funding in January 2026, against the S&P 500 price index. ARGO’s live record is on the performance page. Past performance does not guarantee future results.

Model Release NotesHow the engines evolvedFeatherScale is the stock scoring model LTQS began with. It weighs six families of evidence into one score. Try a ticker.
The system stays on watch through every session, and the engines act only when their rules say so. Most days, nothing trades.
Concentrated portfolios swing hard. What the rules control is the process.
Every term orbiting above is a pillar of the FeatherScale engine. Six families of signals, spanning valuation, risk-adjusted return, market microstructure, distribution statistics, derivatives and sentiment, converge into a single conviction score.
Our first portfolio engine has traded live capital daily since February 2026. Part of its stock screening runs on FeatherScale, the scoring model demonstrated above. Since late July 2026 every order it fills is published on this site, rebalance by rebalance.
Our second generation engine reads the market from a different starting point than DRAUPNIR. Its current build, v11r, has traded live capital on its own account since 27 July 2026, and both engines are plotted side by side on the performance page.
