This study constructs fixed-income fund-of-funds portfolios from products managed by one fund company, considering a setting where the available fund universe is limited. It separates funds into low-, medium-, and high-risk pools based on fund categories,…

This short BigQuant support exchange explains how to obtain historical fund data for use in a backtest. It recommends reading the fund bar data source with a start date and end date, with the backtest's current date supplying the endpoint. The example…

The document outlines high-frequency trading as a way to act on short-term intraday signals and accumulate small gains across trades. It groups strategies into trend-based, spread-based, and market-making approaches, and argues that their returns may…

The document is a short discussion of difficulties encountered by a small-cap strategy in 2024. Its author suggests that adding a value factor may partly address those problems and emphasizes drawdown management or stop-loss actions as an important part of…

This document introduces two ways to estimate the duration of public bond funds. The stated inputs are portfolio holdings disclosed in quarterly fund reports and the fund’s regularly published net asset value. The purpose is to give investors a way to assess…

This brief note introduces the Aroon indicator and names its inputs: high and low prices, a lookback length, and upper and lower bands. It gives formulas for the Up and Down components. Each component is based on how many periods have elapsed since the…

This article outlines a way to study stock selection during broad market declines. It proposes identifying historical selloff days, then examining whether stocks that rose to the daily limit despite the market weakness continue to show strength on the next…

This short Chinese-language discussion addresses why total market capitalization may be classified as a valuation factor in one platform's documentation and as a size factor in research literature. Its answer is that valuation and size factors have some…

The document asks whether feature importance can be obtained from logistic regression, including Lasso-regularized models. Its reply contrasts tree-based importance measures with coefficient-based models and notes that a platform with scikit-learn installed…

This brief BigQuant forum post asks how to build one feature from another when the first feature is a moving-average comparison. The desired first feature assigns a positive value when the five-day average exceeds the ten-day average and a negative value…

The article proposes a short-horizon trading routine built around weekly profit targets and strict loss limits. Its central rule is to enter during the first trading day of the week, exit the full position once total portfolio gains reach 2.5%, and stop…

This paper examines whether deep neural networks can learn delta hedging strategies for options when the idealized assumptions behind Black–Scholes—such as continuous trading and no transaction costs—do not hold. It compares recurrent neural networks,…
