  • Avoid Equity Bear Markets with a Market Timing Strategy – Revisiting Our Research [Quantpedia]

    In March, we posted a series of three articles where our goal was to construct a market timing strategy that would reliably sidestep the equity market during bear markets. Each article focused on trading signals based on a specific group of indicators, namely, price-based indicators, macroeconomic indicators, and a leading indicator, a yield curve, that can predict recessions and bear markets in
  • Research Review | 18 August 2023 | Factor Risk Premia Analysis [Capital Spectator]

    Expanding the Fama-French Factor Model with the Industry Beta Anatoly B. Schmidt (NYU Tandon School of Engineering) August 2023 Recently it was shown that the news-based stock pricing model (NBSPM) outperforms the momentum-enhanced five-factor Fama-French model (FF5M) for a representative list of holdings of the major US equity sector ETFs both in-sample (Schmidt 2023) and out-of-sample (Schmidt

  • Technical Analysis Report Methodology + Double Bottom Country Trading Strategy [Quantpedia]

    We cannot start without a cheap quip: Technical analysis is an astrology for men. Market technicians believe that prices currently contain all information about any asset. It is undoubtedly an oversimplified assumption, as the market is much more complex than that. But suppose you try to use fundamental analysis too harshly. In that case, you assume that you have all the possible information about
  • Quant_rv part 9: why realized vol? [Babbage9010]

    A big issue for me with this project is: how do we validate this whole approach? We started out with a super simple vol-based timing strategy (long/flat market exposure). I rather glibly state that realized (or perhaps more properly, historical) volatility is a sensible, logical, statistically meaningful market observation. But is it? The real low volatility anomaly (documented in

  • New Feature: 10-Year Stock Market Return Forecast [Allocate Smartly]

    We are often asked about stock market valuation models such as Shillers CAPE Ratio and the Buffet Indicator. These models predict long-term returns, usually forecasting the next 10 years. Our recent analysis of one such valuation model, the Aggregate Investor Allocation to Equities, motivated us to take our our own deep dive into the subject. Our goal is two-fold: (a) analyze valuation models
  • Post-Mortem: Losing Money At 36k-Feet Above Sea Level and How Not To [Taiwan Quant]

    Picture this: you're about to board a 10-hour flight. As you board the plane (or maybe some time waiting at the gate), a notification pops up in your pocket. You're busy with other things, so you ignore it and forget about it (in fact, you're used to ignoring notifications because you thought at one point that's the only healthy way to approach them). You walk into the
  • NASDAQ no longer leading the SPX what this means for the market [Quantifiable Edges]

    One particularly notable indicator change that occurred at the close on Friday is that out NASDAQ/SPX Relative Leadership indicator flipped so that it is now showing the SPX as leading and the NASDAQ as lagging. This can be seen in the chart below. NASDAQ/SPX Relative Strength shows NASDAQ faltering now Whenever the solid (green/red) line is above the blue dashed line that means the NASDAQ is
  • GARP Investing: Golden or Garbage? II [Finominal]

  • Business Cycle Sector Timing [CSS Analytics]

    The business cycle is a pattern that captures changes in economic activity over time. The changes in the business cycle occur in a sequential or serial manner, moving through a predictable sequence of phases. These cycles are consistent but vary in both duration and intensity.

  • Generation of Syntactic Quantitative Signals and Alpha Factories [Hanguk Quant]

  • Nowcasting macro trends with machine learning [SR SV]

    Nowcasting economic trends can make use of a broad range of machine learning methods. This not only serves the purpose of optimization but also allows replication of past information states of the market and supports realistic backtesting. A practical framework for modern nowcasting is the three-step approach of (1) variable pre-selection, (2) orthogonalized factor formation, and (3)

  • Value and Profitability/Quality: Complementary Factors [Alpha Architect]

    In his 2012 paper The Other Side of Value: The Gross Profitability Premium, Robert Novy-Marx demonstrated that profitability, as measured by gross profits-to-assets, had roughly the same power as book-to-market (value factor) in predicting the cross-section of average returns profitable firms generated significantly higher returns than unprofitable firms despite having significantly

  • Statistical Shrinkage (2) [Eran Raviv]

    During 2017 I blogged about Statistical Shrinkage. At the end of that post I mentioned the important role signal-to-noise ratio (SNR) plays when it comes to the need for shrinkage. This post shares some recent related empirical results published in the Journal of Machine Learning Research from the paper Randomization as Regularization. While mainly for tree-based algorithms, the intuition
  • Investor demand: can it explain returns? [Alpha Architect]

    The traditional financial theory attributes security returns to market- or factor-based risk, with no role ascribed to other influences. In this research, the authors argue for including investor demand as an additional variable in explaining returns. Can changes in investor demand generate systematic changes in security returns? Overall, our analysis shows that demand effects caused by

  • Why Backtests Run Fast or Slow: A Comparison of Zipline, Moonshot, and Lean [Quant Rocket]

    Backtest speed can significantly affect research friction. The ability to form a hypothesis and quickly get an answer from a backtest allows you to investigate more hypotheses. In this article, I explore several factors that affect backtest speed and compare the performance of 3 open-source backtesters. The backtesters I compare are: Moonshot, a vectorized backtester written in Python Zipline, an

  • Pure macro FX strategies: the benefits of double diversification [SR SV]

    Pure macro(economic) strategies are trading rules that are informed by macroeconomic indicators alone.

  • Retail attention metrics: do they produce differences in returns? [Alpha Architect]

    Abstract: We find that by using a novel measure of investor attention, generated from InvestingChannels clickstream data on online financial news consumption, we can identify broad groups of stocks which are less efficiently priced and therefore where anomalies such as Value and Momentum are likely to produce greater cross-sectional differentiation in returns. We also apply these groupings to
