This brief student response defines quantitative investing as using data, statistics, research, systematic data collection, backtesting, and programmed trading to make investment decisions. It highlights several perceived advantages: a repeatable process,…
This Chinese-language support exchange concerns missing dividend information for Contemporary Amperex Technology in a China A-share data table. The user asks why a recent September distribution, reportedly paid on September 28, does not appear and how to…
This research summary reviews trend-following indicators and how to build strategies for broad asset allocation and industry allocation. It groups 41 indicators by their input data, filtering, moving-average construction, and signal generation, arguing that…
The post asks whether an AI system can infer a profitable futures trader’s approach from minute-level transaction records and then automate similar decisions. The trader reportedly combines minute-bar patterns with discretionary market feel, making the…
The document explains MACD as the difference between a faster and a slower exponential moving average, with a signal line formed as an EMA of MACD. It describes the histogram as the difference between those two lines and gives the common 12, 26, and 9 period…
This brief educational note defines quantitative investing as expressing an investment strategy in code so that a computer can carry out trading in place of manual execution. It identifies reduced emotional interference as one potential benefit of rule-based…
The document explains how factor mining outputs can be connected to strategy research. The mining module produces factor expressions as strings; researchers can then use those expressions to test factor effectiveness and run strategy backtests. It offers no…
This document presents a Chinese-stock ranking workflow built around an XGBoost RankNet model. It constructs price-return and trading-activity features, labels stocks using clipped forward returns divided into quantile bins, and separates training data from…
This article argues for entering strong, rising stocks instead of trying to buy after declines. Its proposed triggers are a break above a consolidation range or a shift from a gradual rise into faster gains, marked by the first large-volume bullish candle.…
The discussion clarifies how to read a BigQuant money-flow factor field whose name ends in a zero window. The question is whether “past zero trading days” means there are no observations to average, even though the description refers to an average net active…
This short troubleshooting note addresses a BigQuant model-training failure that reports a ValueError because a maximum is being computed over an empty sequence. It attributes the problem to a parsing issue when feature or factor names are renamed. The…
This brief indicator note introduces Island Reversal, abbreviated IR, and lists its inputs as close, high, low, a lookback length, and a percentage parameter. Its pseudocode calculates prior-period high and low boundaries, then derives two price levels…
This article contrasts retail investors' execution environment with that of quantitative firms. It describes exchange co-location and direct connectivity as ways to reduce signal and order latency, then discusses how automated systems may react quickly to…
The article discusses two reported measures intended to reduce speed advantages for quantitative firms in China’s A-share market: removing servers located inside exchange facilities and adding latency equivalent to a stated 200-kilometer separation. It…
This 2022 overview describes Hong Kong as a base for international and Chinese quantitative asset managers and as a channel for overseas investors seeking exposure to mainland China. It cites hiring and regional-office examples involving Citadel and Two…
The report describes stock-return prediction with machine-learning models built for short, medium, and long forecast horizons. It groups selection factors according to their information coefficients at different horizons, reflecting the idea that factor…
The post asks whether a feature expression can take the maximum of four moving averages and whether a similar expression can calculate their standard deviation for one day. The example uses 5-, 10-, 30-, and 60-day averages as four contemporaneous values,…
This report outlines a first step in building a multifactor model: choosing which factors to combine. It proposes screening combinations using three criteria: how strongly a factor differs from benchmark exposure, how correlated the factors are with each…
This research summary outlines three refinements to genetic programming for finding stock-selection factors: fitness measures based on mutual information and long-only excess return, ways to transform nonlinear factors, and validation procedures intended to…
The article examines China’s A-share T+1 rule, which generally prevents investors from selling shares on the same day they buy them. It presents four arguments in the debate: the rule may curb impulsive retail trading, constrain some forms of repeated…
This report studies the accuracy of analysts’ consensus earnings-per-share forecasts for China A-shares and develops forecast-bias signals for stock selection. Its full-sample statistics indicate substantial errors and an overall optimistic bias. An…
