  • Trading Strategy Monitoring: Modeling PnL as Geometric Brownian Motion [Portfolio Optimizer]

    Systematic trading strategies have the unfortunate habit of exhibiting worse performances in real-life than in backtests, partially due to backtest overfitting1. Monitoring their behavior once they are deployed in production is then very important to be able to detect as early as possible any inconsistency between their live returns and their expected returns.

  • MOIC: Investing Holy Grail [Quant Dare]

    Many investors are looking for the holy grail of investing. They all want a magic formula that tells them which stocks to buy, and which ones to sell. But experienced investors know that there is no such a thing. I was convinced of it until I discovered the MOIC formula. MOIC Multiple on Invested Capital (MOIC) is a metric used to describe the performance of an investment relative to its

  • Matching data between data sources with Python [Wrighters.io]

    Data is often messy and rarely in perfect shape. This is especially true if the data comes from many different sources and the specifications are loosely defined. If you have access to data that is in great shape, its probably because someone else did the dirty work of validating it, cleaning it up, and normalizing it for you. One particular type of data problem is matching data between data
  • Skewness: the fallacy of the expected return [Artifact Research]

    In this post we will take a closer look at the expected return that is often stated for investments like stocks and other financial assets, or for certain outcomes in gambling. The point we want to convey is that the expected return is only valid for one period or a single iteration (say, one year, or one round of a game such as Blackjack), but that the expected return can be highly
  • The Cross Section of Stock Returns Pre CRSP data [Alpha Architect]

    What are the Research Questions? Several studies reveal variables that predict cross-sectional differences in stock returns but mainly rely on a sample of U.S. stocks, mostly covering the post-1963 period. These studies are often criticized for potential data mining issues since the database never changes, but new findings crop up all the time. This paper studies the cross-section of U.S.

Pandemics were nothing new, of course, but
  • Market Risk and Speculative Factors [Alpha Architect]

    There are basically two types of investors, those that are risk averse and, thus, both demand risk premiums for taking risk and diversify their holdings, and those who are risk seekers who have a preference for positively skewed (lottery-like) returns which leads them to speculate and concentrate risks. The psychological preferences of risk seekers drives up the valuations of the lottery-like

  • Optimal trend following allocation under conditions of uncertainty [Investment Idiocy]

    Few people are brave enough to put their entire net worth into a CTA fund or home grown trend following strategy (my fellow co-host on the TTU podcast, Jerry Parker, being an honorable exception with his 'Trend following plus nothing' portfolio allocation strategy). Most people have considerably less than 100% – and I include myself firmly in that category. And it's probably true

  • Slava Ukraini! Latest from Quantocracy contributor in Ukraine: Volatility and Price of a Straddle, Are They The Same? [Only VIX]

    Yesterday I found another piece of ignorance on Medium: Stop Watching The VIX, Just Make Your Own tl;dr : Just use ATM straddles. This is of course not correct. As I have written before on this blog that (skipping mathematical rigor) the value of ATM straddle is or about 80% of the expected volatility. So if SPY = $400 and VIX = 20, the expected volatility is $400 * 20/100 = $80, then 1 year ATM
  • Volatility-based Equity Allocations [Finominal]

    The VIX currently trades within its top quartile since 1990 Using volatility to time equity allocations is a widely used strategy However, it is challenging to pursue this over the long-term INTRODUCTION The One Ring from J.R.R.

  • Momentum Gap – its role in reducing crashes [Alpha Architect]

    This article discusses the academic research about the Momentum Gap and the role that its predictive potential may have in reducing momentum crashes, hence possibly improving performance. In our book Your Complete Guide to Factor-Based Investing, Andrew Berkin and I presented the evidence demonstrating that momentum, both cross-sectional (CSMOM) and time-series (TSMOM), has provided a
  • Identifying market regimes via asset class correlations [SR SV]

    A recent paper suggests identifying financial market regimes through the correlations of asset class returns. The basic idea is to calculate correlation matrixes for sliding time windows and then estimate pairwise similarities. This gives a matrix of similarity across time. One can then perform principal component analysis on this similarity matrix and extract the axes of greatest relevance.

  • Are hedge funds losing their hedge? [Mathematical Investor]

    Hedge funds were pioneered some 70 years ago by Australian financier Alfred Winslow Jones. His idea was to combine a long position (i.e., one that profits if the securities go up in price), typically a set of growth stocks, with a short position (i.e., one that profits if the securities go down in price) on the other part of the portfolio. Jones argued that this long-short

  • Correlation Matrices Denoising: Results from Random Matrix Theory [Portfolio Optimizer]

    The estimation of empirical correlation matrices in finance is known to be affected by noise, in the form of measurement error, due in part to the short length of the time series of asset returns typically used in their computation1. Worse, large empirical correlation matrices have been shown to be so noisy that, except for their largest eigenvalues and their associated eigenvectors, they can

  • Causality: interest rates and fixed income assets [Quant Dare]

    The blog has previously addressed interest rates in a post that splits the yield rate curve into three relevant components. This time this post tries to identify the influence of interest rates on fixed income assets by using the Granger causality test. Interest rates obviously have a strong impact on fixed income assets because they are the base to compute their prices. However, can we find any

  • Finding and analyzing free stock index data with Python and EDGAR [Wrighters.io]

    A stock index is just a list of stocks. But an index is a special list because investors use it to make investing decisions.

This is especially the case if you want to find this data for free. This article will
