This article outlines an asset allocation method that combines risk parity with the Black-Litterman framework. Risk parity portfolio weights serve as prior weights, which are used to infer prior expected returns. Short-term momentum views are then…
This article explains how to model multi-stock trading as a Markov decision process and train a deep deterministic policy gradient (DDPG) agent with FinRL. The state includes prices, holdings, and cash; actions change holdings through buying, selling, or…
This weekly review summarizes Chinese equity market conditions for the week ending April 3, 2020, then presents Haitong Securities’ market timing, factor, industry rotation, and strategy-performance views. Its evidence includes index returns, valuation and…
This brief BigQuant forum exchange concerns errors in a factor-analysis template when a factor’s coverage falls below the platform’s threshold. One concrete cause is division by zero: the expression using the difference between the high and close prices can…
This essay groups purportedly successful stock market participants into six styles: patient traders who wait for rare setups, long-term value investors, specialists focused on one stock, short-term leaders-of-the-hot-sector traders, traders who repeat a…

This support note explains how to access trade details from a BigQuant backtest. It says the trade detail page does not offer a direct export, and recommends downloading the results for separate analysis. It also points users to the backtest module’s raw…
The post compares a hand-built 120-period Commodity Channel Index calculation with the platform’s built-in CCI function and asks why their results differ. It identifies the typical price as the average of the high, low, and close, then describes a formula…
This BigQuant forum post describes a custom Python module that runs successfully in AIStudio 3.0 but fails when submitted as a scheduled data task. The example reads the latest stored date, loads a local CSV of Bitfinex symbols, requests newer daily market…

This research summary presents TS-Boost, an equity factor-selection framework designed for financial data with shifting cross-sectional patterns and low signal-to-noise ratios. Instead of pooling observations from different dates into one training set, it…
This discussion describes a model-stacking problem in a Chinese quantitative research platform. A user has trained and persisted twenty StockRanker models using the same factor set but differing in date ranges, data filters, or prediction horizons. The goal…
