This market note summarizes a difficult week for major Chinese equity indexes and sectors, then reports changes in factor behavior. It says quality and analyst sentiment factors strengthened relative to the prior week, while value, reversal, and alternative…
This Chinese language literature digest summarizes research on return predictability and portfolio covariance estimation. One study examines stock prices and dividends in the Netherlands, the United Kingdom, and the United States over nearly four centuries.…
This research summary examines how broad equity factors behaved across Chinese A-share industries from July 2009 through November 2018. It links differences in factor effectiveness to industry characteristics: small-cap effects were stronger in industries…
This tutorial introduces two strategy-building approaches on BigQuant: an AI-driven workflow that trains a model from selected factors and filters, and a user-coded approach with explicit selection rules. It focuses on the latter, outlining how to clone a…
This BigQuant example assembles a China A-share workflow from stock selection through backtesting. It selects eligible main board, STAR Market, and ChiNext stocks associated with the CSI 1000, then calculates current and lagged volume relative to a five-day…
This meetup note explains factor exposure as an asset’s sensitivity to factor returns. It sketches a way to estimate that sensitivity: form a low-versus-high valuation long-short portfolio, treat its return series as the factor return, and regress an asset’s…
This legacy platform example shows how to model a stock purchase at a specified price relative to the day’s open. A custom slippage model sets buy orders at 98% of the opening price, while sell orders use the current close. A daily order check compares the…
This discussion examines how to exclude Chinese convertible bonds after an issuer announces early redemption. The author found that the platform’s redemption-terms table showed one row each for two example bonds, including contractual trigger conditions,…
This article discusses practical choices when tuning a short-term stock-selection strategy: starting capital, number of holdings, capital allocated per holding, holding period, and factor selection. Its author argues that the number of names and per-name…
The document examines whether rolling Fama-French five-factor (FF5) alphas can guide U.S. sector rotation. It compares FF5 with the three-factor model (FF3), using monthly returns for ten U.S. industry portfolios from 1964 to 2014. The rotation signal is…
This Chinese-language assignment turns a discretionary trading idea into a simple rule for constituents of the CSI 300: buy when the five-day moving average crosses above the ten-day average and MACD is positive, and sell otherwise. It also sketches a…
This research summary tests whether negative sentiment in posts on Xueqiu, a Chinese investing forum, can help time major Chinese equity indexes. It describes using machine learning to classify post sentiment and building a weekly negative-sentiment ratio…
The article summarizes research on how speculative stocks perform around earnings announcements. It measures speculative characteristics using proxies such as maximum daily return, idiosyncratic volatility, price, expected skewness, and jackpot probability,…
This brief support exchange asks how the numbers displayed after decision branches in a visual stockRanker model are calculated. The response points the reader toward material on tree models and information entropy, implying that the displayed values relate…
The article introduces quantitative trading as the use of mathematical models, statistical analysis, historical and real-time market data, and algorithms to guide or automate decisions. It describes stock screening and rule-based execution as common…
This brief support exchange addresses a user’s report that a hyperparameter module raises a key error even though the key appears in the visual chart and can be found in code-mode parameters. The response attributes the issue to an error in the…
This forum post describes an attempted 12–1 momentum strategy on S&P 500 constituents and reports two backtest problems: target-percent orders repeatedly encounter null prices, and a visual workflow produces no instruments or trades. The strategy ranks…
This brief describes a deep neural network approach intended for quantitative stock selection. Its stated implementation goals are to run on systems with limited memory, use GPU acceleration when available, and adapt the number of input features. It also…
The article explains five behavioral traps that it associates with retail trading losses: confirmation bias, reacting to noisy opening-auction signals, trying to recover losses through riskier trades, loss aversion that delays selling, and greed that delays…
This meetup Q&A surveys several quantitative trading topics: using Level 2 order-book data, reproducing a legacy strategy, allocating idle capital to a gold ETF, factor decomposition, building CNN strategies, and portfolio optimization. Most answers point…
This forum post records an attempt to create an A-share factor from securities appearing on the trading ranking list, using a transaction category and several broker department codes. The submitted expression tests whether the category matches a specified…
The article presents a scenario analysis of how sustained high crude prices could affect energy-importing and energy-exporting economies. It argues that higher energy costs may shift income toward resource exporters, raise manufacturing expenses in importing…
The document introduces the task of developing a complete strategy from daily factors extracted with a high-frequency expression engine. It identifies strategy development as the topic of a meetup presentation and points readers to a related recording, but…
This report examines listed companies’ interest-bearing debt as a quantitative stock-selection and risk-screening measure. It defines the debt measure around short-term and long-term borrowings and bonds, and observes that debt ratios tend to reflect…
