  • Trading a Complete Starter System Live with @AlpacaHQ [Raposa Trade]

    Weve spent the past few posts building up the Starter System laid out in Rob Carvers book, Leveraged Trading. Weve gone from a simple moving average cross-over model, to a volatility targeting system with multiple instruments and time frames that dynamically sizes and re-positions your portfolio as market conditions change. Youve done all this work, now its time to make it pay off
  • Yet Another Improved RSI [Financial Hacker]

    John Ehlers strikes again. The TASC January 2022 issue features another indicator supposedly improved with Hann windowing the RSIH, a RSI with Hann flavour. Can it beat the standard RSI? The RSI is basically the normalized difference of price up/down movements. And its here presented Hann variant filters the price differences with a Hann window that was described in a previous article on this
  • Self-organizing maps for clustering [Quant Dare]

    We can use self-organizing maps for clustering data, trained in an unsupervised way. Lets see how. This week we are going back to basics, as we will see one of the first successfully deployed machine learning algorithms: self-organizing maps (SOM, sometimes also called Kohonen maps). This is an unsupervised technique, so we will not need any labeled data for training, just raw inputs.
  • A Stab at Fiction (Unrelated to Quant, but we support our friends) [Following the Trend]

    When I wrote my first book a decade ago, I didnt expect it to get much attention, or sales. I was in the wrong country, of the wrong nationality, I had shunned social media and was nearly invisible on the internet. On top of these obstacles, I tried out a whole new style of writing trading books. It was quite shocking when I saw that book take off and hit the number one slot on the

  • Estimating Rebalancing Premium in Cryptocurrencies [Quantpedia]

    A long time ago, before elevators were a thing, a simple mechanism was used to get the miners in and out of the mines. This mechanism is called a Man Engine (or Fahrknst in German language) and works on a simple principle of two reciprocating ladders and stationary platforms. The two ladders move up and down, so if a miner stands on one platform, he is not going anywhere. However, if
  • An Important Test for the Global Growth Cycle [Grzegorz Link]

    Whatever kind of strategy you're employing as an investor, an invaluable tool for determining it's usefulness is testing. Not simply backtesting on historical data or stress testing on synthetic data that's the easy part. The fun and playful part. A much more important test comes with a strategy's performance on new, real-time data. A couple of months have passed since
  • Quantitative Analysis of a Sample Drawn from the Unknown Continuous Population [Quant at Risk]

    In quantitative finance, we very often deal with a sample mean and sample standard deviation being derived given a vector or a time-series or any other (1-dimensional) dataset. For many of us these calculations are so obvious that only a few understand the principles standing behind the scene. Lets give a second look at this trivial problem. Trust me, you wont regret! 1. Drawing a Random
  • ETFs for Rising Interest Rates [Factor Research]

    A wide range of strategies are marketed as beneficiaries of rising interest rates Portfolios are comprised of equities, bonds, options, long as well as short positions However, only financial services companies and short bonds offer a positive correlation to interest rates INTRODUCTION In this year, most developed markets have been experiencing inflation last seen decades ago, with the exception

  • Back to basics: PCA on stocks returns [Gautier Marti]

    A short code snippet to apply PCA on stocks returns. No secret sauce is used here to clean the empirical covariance matrix. This blog post will mostly serve as a basis for comparing several flavours of PCA and their impact on ex-ante volatility estimation. We may look in future blog posts into Sparse PCA, Nonlinear PCA, Kernel PCA, Robust PCA, revisit our previous implementation of Hierarchical
  • The risk-reversal premium [SR SV]

    The risk reversal premium manifests as an overpricing of out-of-the-money put options relative to out-of-the-money call options with equal expiration dates. The premium apparently arises from equity investors demand for downside protection, while most market participants are prohibited from selling put options. A typical risk reversal strategy is a delta-hedged long position in out-of-the-money

  • Synthetic Lending Rates Predict Subsequent Market Return [Quantpedia]

    It is indisputable that the data are changing financial markets computing power has increased, allowing to rise the trends of ML/AI and big data (number of possible predictors or granularity) or HFT strategies.

  • New Site: Financial market data analysis with pandas (h/t @PyQuantNews) [Wrighters.io]

    Pandas is a great tool for time series analysis of financial market data. Because pandas DataFrames and Series work well with a date/time based index, they can be used effectively to analyze historical data. By financial market data, I mean data like historical price information on a publicly traded financial instrument. However, any sort of historical financial information can be analyzed. Time

  • US Market Valuations: Looking down the Abyss! [Nava Capital]

    Value investing is at its core the marriage of a contrarian streak and a calculator. S. Klarman The first principle is that you must not fool yourself, and you are the easier person to fool. R. Feynman In this brief note, our goal is to show readers, as objectively as possible, the current discrepancy between the intrinsic and the current value of the S&P 500. Our conclusion is
  • Stock Market Returns and Volatility [Factor Research]

  • You Thought P-Hacking was Bad? Let’s talk about “Non-Standard Errors” [Alpha Architect]

    Most readers are familiar with p-hacking and the so-called replication crisis in financial research (see here, here, and here for differing views). Some claim that these research challenges are driven by a desire to find positive results in the data because these results get published, whereas negative results do not get published (the evidence backs these claims). But this research project
  • Book Review: Advanced Portfolio Mgmt – A Quant’s Guide for Fundamental Investors [Gautier Marti]

    Great book, I absolutely recommend. Precise and concise (less than 200 pages). This book will especially be useful to grads or analysts in the early stages of their career. A junior analyst/quant/data scientist who masters the content of this book will definitely be useful in a pod of fundamental discretionary portfolio managers and analysts. This book wont teach you anything about how to
  • Market data, investor surveys, and lab experiments [Alex Chinco]

    An asset-pricing model is a claim about which optimization problem people are solving when they choose their investment portfolios. One way to make such a claim testable is to derive a condition that should hold if people were actually solving this optimization problem. And the standard approach to testing whether an asset-pricing model is correct involves using market data to estimate the key
  • Size, Value, Profitability, and Investment Factors in International Stocks [Alpha Architect]

    The current workhorse asset pricing model is the Fama-French five-factor model (2015), which added the profitability and investment factors to their original (1992) three factors of market beta, size, and valueincreasing the models explanatory power. Nusret Cakici and Adam Zaremba contribute to the factor literature with their May 2021 study, Size, Value, Profitability, and Investment

  • My trading system [Investment Idiocy]

    I realise that I've never actually sat down and described my fully automated futures trading system in all it's detail; despite having runit for around 7.5 years now. That isn't because I want to keep it a secret – far from it! I've blogged or written books about all the various components of the system. Since I've made a fair few changes to my over the last year or so, it

  • Volatilities and Correlations of Cross Rates, a Geometrical Understanding [Quant Dare]

    In this post we will show how the properties of a triangle can be used to intuitively obtain insights about the volatilities and correlations of currency pairs. Once the dominant branch of mathematics, geometry plays now a secondary role. However, its graphical arguments still seem to be better suited for our brains, as they are often easier to understand and to remember. This is the path followed

  • A Complete Starter System for New Traders: Trading Multiple Instruments [Raposa Trade]

    Systematically trading a single instrument can be a bit dull. There are times when your chosen stock isnt trending or doing much. So your system just sits there and waitsand waits..and waits.

  • Can Prospect Theory Explain the Value and Momentum Factors? [Alpha Architect]

    Traditional finance academics lean towards risk-based models to explain why various return characteristics, such as value and momentum, predict returns. But there is another school of thought often referred to as behavioral finance. This field has some of its own ideas (see below) on why different stock factors might predict returns. Prospect Theory was first introduced by Kahneman and
