The document introduces graph representations for modeling relationships among financial assets, arguing that stocks cannot be understood solely as independent observations. Graphs can encode different kinds of links, including sector membership, return…

This post proposes screening stocks in the beverage and alcohol import-export industry using an RSI below 65 and a Morning Star candlestick pattern. The RSI is calculated over 14 periods, while the candlestick signal is identified from open, high, low, and…

This research overview describes two broad approaches to absolute-return investing: combining equities and bonds, and hedging or taking exposures through derivatives. It lists stock-bond rebalancing, target-volatility, risk-parity, and risk-budgeting…

This report studies cases where Chinese listed companies’ annual earnings forecasts later change, either through a revision announcement or a discrepancy in the formal results. It uses a multinomial Logit model to assess whether company financial data,…

This overview presents QLib as an open-source quantitative research platform that supports data preparation, model training, portfolio construction, risk analysis, backtesting, and execution research. It notes support for supervised learning, market-dynamics…

This brief strategy note proposes ranking or selecting stocks by the deviation in price impact associated with five-minute capital flows. Its stated hypothesis is that stocks with smaller price-impact deviations perform better later; it describes these as…

The document summarizes the ResNet paper’s approach to training deep convolutional neural networks. Instead of having stacked layers learn a full transformation directly, residual learning lets them learn a change relative to their input. The paper’s…
