This research summary studies Chinese home appliance industry conditions using revenue and net profit growth as proxies, arguing that calculations on comparable constituents reduce distortions caused by changes in the historical stock universe. It frames…
This weekly review tracks the returns and direction changes of 16 equity factors in the Chinese market during the 25th week of 2018. It reports that sales net margin had the strongest weekly performance, while valuation factors remained weak and the size…
The document describes a deep learning model intended to estimate a company’s next-quarter operating revenue year-over-year growth. It frames the forecast as a potential input to value-oriented investment decisions and says the target corresponds to roughly…
This document is a brief summary of a research presentation on changes in quantitative investing. It outlines a model that combines a linear factor component with a nonlinear function of factor exposures, leaving a residual term. It says that residual…
This forum post questions the target-return calculation in a one-day equity strategy’s labeling code. The strategy is described as buying near the open on one day and selling at the close of the next, yet the label reportedly divides a later session’s high…
This forum post raises operational problems encountered after submitting previously successful stock strategies for simulated trading. The author reports that some buy instructions appear a day early and are later marked invalid, that incomplete purchases…
This report summary describes an index-timing model that applies wavelet analysis to filter price series before using a support vector machine to predict direction. It compares daily and weekly data and different model settings for the Shanghai Composite and…
This research summary introduces the “Huayin Linjian” factor as a way to identify A-shares that may be undervalued because their prices have not been strongly driven by information-related trading pressure. Its stated premise separates price movements into…
This brief strategy outline combines a machine-learning stock ranking model with market-level and individual-stock exit rules. It proposes training a StockRanker on price, volume, and valuation factors, then applying three conditions to the CSI 300 index as…
This tutorial demonstrates a workflow for evaluating WorldQuant Alpha#100 on Chinese equities. It builds the factor from price and volume signals, including the close’s position within the daily range, the relationship between closing price and ranked…
The report reviews how to assess pure bond funds using disclosed portfolio data, covering asset allocation and leverage, bond-type exposure, concentration, duration, and turnover. It then explains bond performance attribution, contrasting Campisi with…
This essay challenges the idea that time in the market reliably produces trading skill. It argues that experience can reinforce poor habits, while trading decisions are better treated as probabilistic choices whose quality depends on having a statistical…
The strategy ranks CSI 300 constituents by their return over the first three trading days of each month, measured from the first day's open to the third day's close. If the month has at least four trading days, it buys the ten strongest eligible stocks at…
This report reviews the issuance and performance of Chinese private CTA products in the first quarter of 2018, then discusses equity index futures, government bond futures, and commodity markets. It links strategy ideas to changes in volatility, trading…
The report compares machine learning approaches with traditional linear methods for predicting stock-level excess returns from alpha factors. Rather than predict excess return directly, it forecasts return dispersion with an AR(1) model and predicts…
This article argues that some quantitative strategies in China’s A-share market focus on exploiting short-term price fluctuations rather than company fundamentals. It portrays rapid trading as a source of high turnover and a potential conflict with the…
This weekly note assesses the Chinese equity market using trend, liquidity, options sentiment, macroeconomic data, calendar patterns, and factor crowding. Its timing framework treats the market as bullish when the broad-market index is above its 20-day…
This summary of a Huatai Securities research report discusses using alternative target labels and ensemble learning to improve machine-learning stock selection. It reports comparing models built with different labels across multiple training-window lengths.…
This Chinese equity research report builds a stock-selection factor from how each stock’s trading value co-moves with the rest of the market under two conditions. When a stock is relatively high in its recent intraday range, stronger co-movement is…
This meetup Q&A discusses several practical questions in quantitative research. It explains that traders can label chart patterns for AI training in principle, but visual labels may vary with chart scale and between annotators. A model can only learn useful…
The document explains why a portfolio weight constraint routine can fail when it caps bond exposure and then normalizes all weights. Normalization may push the bond allocation above its intended limit; the example describes a bond weight of 20% becoming 40%…
This lecture listing introduces policy-gradient methods, which learn a policy directly, and actor-critic methods, which pair a policy learner with a value estimator. The description highlights the actor-critic combination as a way to use value predictions to…
The post asks why a BigQuant strategy raises a parser error near FROM. Its factor expression defines several intraday features, including a bid-ask spread measure, weighted order-book volume imbalance, early-session price movement, and a volume ratio, then…
This post reports a suspected mismatch in BigTrader v35 minute backtests after an ETF share split. The author says the strategy-visible position fields—quantity, cost price, last price, and market value—appeared to retain their pre-split values, while a…
