  • Macroeconomics with Gaussian Mixture Models [OS Quant]

    Returns can be viewed as a product of an underlying market regime. This article models those regimes and shows how to extend the model with macroeconomic variables to link regimes to observable economic indicators. Some time ago I read a Two Sigma article on using Gaussian mixture models for regime detection 1. I wanted to understand the math behind these methods and extend them by tying the
  • QuantMinds London 2025 [Turnleaf Analytics]

    Are you on mute? is perhaps the most succinct catchphrase which most comprehensively describes the post-covid landscape of work. Yet, despite the plethora of video conferencing tools out there, there is still something to be said for being there in person. If anything, the sheer volume of virtual interactions means that a real interaction becomes more valuable. If you really want
  • Rethinking Growth Investing: Why Traditional Growth Indices Miss the Mark [Alpha Architect]

    Historically, the finance community (both academics and investment firms) has divided stocks into two categories: cheap and expensive. Initially, the book-to-price ratio was used to allocate stocks into growth (expensive) or value (cheap) indices. Other metrics, such as price-to-earnings, price-to-sales, and price-to-cash flow, are now also commonly used. What was not value was growth and vice

  • Dual Momentum & Global Growth Cycle Enhanced [Grzegorz Link]

    The Dual Momentum approach, formalized in Gary Antonacci's 2012 paper[1] and later popularized in his book,[2] is a surprisingly simple yet potent tactical asset allocation strategy. It builds on the fact that assets experience both absolute [time series] momentum, as well as relative [cross-section] momentum, and utilizes both of these effects in its goal of returning better-than-passive
  • Weekly Research Recap [Quant Seeker]

    Asset Allocation Tactical Asset Allocations of Large Asset Managers (Ibert) Large asset managers tactical views closely follow their assessments of global growth and recession risk. When growth prospects deteriorate, they cut equity exposure and increase bond allocations. A move from overweight to underweight equities reduces equity weights by roughly 1.83.2 percentage points. Key takeaway:
  • Switch-Off: Bayesian online changepoint detection [Trading the Breaking]

    Every quantitative trading operation, from a single retail algorithmist to a multi-billion dollar systematic fund, faces an identical, recurring, and fundamental dilemma: When to deactivate a failing strategy. This problem is, in many ways, the only problem that matters for long-term survival. Alpha is finite. All strategies eventually decay. The persistence of a quant fund is not determined by
  • Fractal Market Hypothesis: From Theory to Practice [Relative Value Arbitrage]

    Fractal Market Hypothesis is an alternative framework that models financial markets through long-memory and multi-scale dynamics. There is a growing trend in the industry to incorporate itfirst in analyzing the behavior of underlying assets, and more recently in the pricing of financial derivatives such as futures.

  • Leveraged ETFs in Asset Allocation: Opportunity or Trap? [Quantpedia]

    In this article, we explore whether it makes sense to incorporate leveraged ETFs into static and dynamic long-only asset allocation strategies. Leveraged ETFs promise amplified exposure to the underlying asset, offering the potential for significantly higher returns during favorable market conditions. However, this comes at the cost of much higher volatility, path-dependency, and the well-known
  • Wordle (TM) and the one simple hack you need to pass funded trader challenges [Investment Idiocy]

    An unusual (but quick) mid month post, as this is a live issue I thought I'd publish this whilst it's relevant. There has been some controversy on X/Twitter about 'pay to play' prop shops (see this thread and this one) and in particular Raen Trading. It's fair to say the industry has a bad name, and perhaps this is unfairly tarnishing what may pass for good actors in this
  • Research Review | 14 November 2025 | Bubble Risk [Capital Spectator]

    Bubble Beliefs Christian Stolborg (Copenhagen Bus. School) and Robin Greenwood (Harvard) October 2025 We study expert beliefs during boom-bust episodes in which highly valued individual US stocks experience a price run-up followed by a crash.

  • How to Design a Simple Multi-Timeframe Trend Strategy on Bitcoin [Quantpedia]

  • Is predicting vol better worth the effort and does the VIX help? [Investment Idiocy]

    I'm a vol scaler. There I've said it. Yes I adjust my position size inversely to vol. And so should you. But to this well we need to be able to predict future vol; where the 'future' here is roughly how long we expect to hold our positions for. Some people spend a lot of effort on this. They use implied vol from options, high(er) frequency data, GARCH or stochastic vol models.
  • Weekly Research Recap [Quant Seeker]

    What 200 Years of Data Tell Us About the Predictive Variance of Long-Term Bonds (Della Corte, Gao, Preve, and Valente) Over two centuries of data show that the risk of holding long-term foreign bonds without currency hedging increases with the investment horizon rather than mean-reverting. The dominant sources of uncertainty are exchange rate fluctuations and shifts in monetary and interest-rate
  • Denoising Correlation Matrices for More Stable Portfolio Optimization [Sitmo]

    Portfolio optimization lies at the heart of asset management, guiding investment strategies from risk minimization to return maximization. Many of the most widely used allocation methods such as minimum variance, maximum Sharpe ratio, and risk parity rely on the inverse of the correlation matrix to compute optimal portfolio weights. However, if the correlation matrix is poorly conditioned (i.e.,

    The results of the first set of tests of optimising an indicator via the framework of training a neural net are in, and this post is a presentation of these results and a reflection on this in more general terms. I would encourage readers to look at my previous 2 posts to put this one in context. The following chart plot shows 8 weeks of 10 minute price action in the EURUSD forex pair, with the
  • The Factor Mirage: How Quant Models Go Wrong [CFA Institute]

    Factor investing promised to bring scientific precision to markets by explaining why some stocks outperform. Yet after years of underwhelming results, researchers are finding that the problem may not be the data at all; its the way models are built. A new study suggests that many factor models mistake correlation for causation, creating a factor mirage. Factor investing was born from an

  • R squared and Sharpe Ratio [Investment Idiocy]

    Here's some research I did whilst writing my new book (coming next year, and aimed at relatively inexperienced traders). Imagine the scene. You're a trader who products forecasts (a scaled number which predicts future risk adjusted returns, or at least you hope it does) who wants to evaluate how good you are. After all you've read Carver, and you know you should use your expected
  • Thanksgiving and Christmas Trading Strategies [Quantpedia]

    This article examines the impact of major consumer holidays, Thanksgiving and Christmas, on financial markets. Using historical price data from 2004 to 2024, we analyze daily performance trends in the 10 trading days before and after each holiday to determine whether seasonal spending influences asset prices. Our findings suggest that seasonal consumer spending influences financial markets, with
  • ChatGPT in Systematic Investing – Enhancing Risk-Adjusted Returns with LLMs [Concretum Group]

    This paper investigates whether large language models (LLMs) can improve cross-sectional momentum strategies by extracting predictive signals from firm-specific news. We combine daily U.S. equity returns for S&P 500 constituents with high-frequency news data and use prompt-engineered queries to ChatGPT that inform the model when a stock is about to enter a momentum portfolio. The LLM evaluates
  • Value at Risk: Univariate Estimation Methods [Portfolio Optimizer]

    Value-at-Risk (VaR) is one of the most commonly used risk measures in the financial industry1 in part thanks to its simplicity – because VaR reduces the market risk associated with any portfolio to just one number2 – and in part due to regulatory requirements (Basel market risk frameworks34, SEC Rule 18f-45). Nevertheless, when it comes to actual computations, the above definition is by no

  • Features Selection in the Age of Generative AI [Gatambook]

    Features are inputs to machine learning algorithms. Sometimes also called independent variables, covariates, or just X, they can be used for supervised or unsupervised learning, or for optimization. For example, at QTS, we use more than 100 of them as inputs to dynamically calibrate the allocation between our Tail Reaper strategy and E-mini S&P 500 futures. In general, modelers have no idea
  • Sensitivity Analysis 101 [Factor Research]

    SUMMARY Sensitivity analysis can highlight portfolio risks However, it is sensitive to data availability and assumptions Focusing on tail betas is sensible INTRODUCTION The U.S. stock market is currently being driven by a small group of stocks, creating a concentration risk not seen in decades. While comparisons to the 2000 tech bubble are common, a key difference is that todays leading
  • Weekly Research Recap [Quant Seeker]

    The Term Structure of Stock-Bond Covariances (Gandhi) After 2009, the term structure of stockbond covariances turned downward-sloping, with long-maturity bonds providing a stronger equity hedge than short-maturity bonds. A new stockbond factor based on these covariances predicts bond excess returns (R > 20%) after 2010. Key takeaway: Unconventional monetary policy post-GFC affected the
  • How does inflation impact trading? [Alpha Architect]

    A growing body of research suggests that inflation doesnt just erode purchasing power it reshapes how financial markets function. This paper shows that when inflation rises, trading behavior changes in systematic ways: liquidity deteriorates, bid-ask spreads widen, and investors trade less on fundamentals and more on short-term noise. These effects amplify volatility and reduce
  • Modeling Gold for Prediction and Portfolio Hedging [Relative Value Arbitrage]

    Gold prices have risen sharply in recent months, prompting renewed debate over whether the market has reached its peak. In this post, we examine quantitative models used to forecast gold prices and evaluate their effectiveness in capturing volatility and market dynamics. However, gold is not only a speculative vehicle, it also functions as an effective hedging instrument. We explore both aspects

  • Can Technology Sector Leadership Be Systematically Exploited? [Quantpedia]

    The U.S. equity market has periodically been dominated by a few technology-driven stocks, most recently the so-called Magnificent Seven. Historically, similar dominance occurred during the Nifty Fifty era in the 1960s1970s and the dot-com boom in the 1990s. These periods of concentrated leadership often led to temporary outperformance, but systematically capturing such gains has proven
  • The crucial difference in price momentum vs. earnings momentum [Klement on Investing]

  • Why You Can t Tell if Your Strategy Stopped Working (Statistically Speaking) [Robot Wealth]

    Traders love the illusion of precision. A few bad weeks go by, and you think, Lets run a t-test and see if the strategy stopped working. It sounds rigorous. It isnt.

  • The Points-and-Line Chart [Financial Hacker]

    -and-Line Chart Traders like special bars on a chart, since they let the price curve appear smoother and more predictable as it really is. Some types of bars, such as Renko bars, even use fake prices for generating curves that appear to move straight upwards or downwards. In the TASC November issue, Mohamed Ashraf and Mohamed Meregy presented the Points and Line Chart that avoids this problem. At
  • Weekly Research Recap [Quant Seeker]

    Analyzing over 1,500 bond funds (20152024) shows that active returns, performance relative to benchmarks, are driven mainly by systematic risk exposures, not manager skill. For Aggregate and Corporate funds, about 55% of active returns come from underweighting duration and overweighting credit risk, while high-yield funds often reduce credit exposure. Key takeaway: Active return is not alpha;
