  • Find Your Best Market to Trade With the Hurst Exponent [Raposa Trade]

    After five consecutive years of drought, Northern Californians welcomed the heavy rainfall in the winter of 2016-2017.

You may also want to evaluate your model by setting up a benchmark or determining its weaknesses using different sets of data. Sometimes, you may also want to create synthetic datasets, where you can test your algorithms under
  • Is Sector-neutrality in Factor Investing a Mistake? [Alpha Architect]

    Firm characteristics such as size, book-to-market ratio, profitability, and momentum have been found to be correlated with expected returns. The predictive power of these characteristics may stem from their industry component, their firm-specific component, or both.

  • Simple Machine Learning Models on OrderBook/PositionBook Features [Dekalog Blog]

    This post is about using OrderBook/PositionBook features as input to simple machine learning models after previous investigation into the relevance of such features. Due to the amount of training data available I decided to look only at a linear model and small neural networks (NN) with a single hidden layer with up to 6 hidden neurons. This choice was motivated by an academic paper I read online

  • Benford s Law and Strategy Selection [Alvarez Quant Trading]

    While talking to a trader, he mentioned an article in the December 2021 issue of Technical Analysis of Stocks & Commodities about Benfords Law. I had read the same article and was wondering how it could be applied to my trading. Benfords Law is often used to look for fraud. I am sure I am not committing fraud on myself.

  • Why 90% of Backtests Fail [Financial Hacker]

    About 9 out of 10 backtests produce wrong or misleading results. This is the number one reason why carefully developed algorithmic trading systems often fail in live trading. Even with out-of-sample data and even with cross-validation or walk-forward analysis, backtest results are often way off to the optimistic side. The majority of trading systems with a positive backtest are in fact
  • Optimize Your Trading Strategy With Python And The Kelly Criterion [Raposa Trade]

    Retail traders almost always have small trading accounts. To get the returns they're after, traders frequently take on leverage – often times imprudent amounts in highly levered FOREX accounts that can be levered 50-100x! Retail equity brokers are a bit more conservative with maximum leverage ratios of 2-3x. Leverage is a dangerous thing to play with – and we don't recommend
  • Gaining an Edge via Textual Analysis of FOMC Meetings [Alpha Architect]

  • Equity convexity and gamma strategies [SR SV]

    Equity convexity means that a stock outperforms in times of large upward or downward movements of the broad market: its elasticity to the market return is curved upward. Gamma is a measure of that convexity. All else equal, positive gamma is attractive, as a stock would outperform in market rallies and diversify in market stress. However, gamma is not observable, changeable, and needs to be

  • Mean-Variance Optimization: Well Diversified (Near) Efficient Portfolios [Portfolio Optimizer]

    One well-known stylized fact of the Markowitzs mean-variance framework is that, irrespective of the quality of the estimates of asset returns and (co)variances, efficient portfolios are concentrated in a very few assets1.

  • Are Stock Market Bubbles Identifiable? [Alpha Architect]

    We can define an investment bubble as an irrational strong price increaseimplying a predictable strong decline.

In his Nobel Prize lecture, the father of the EMH, Eugene Fama stated: The available research provides no reliable evidence that stock market price declines are
  • Yield Curve Inversions and SPX Returns [Quantifiable Edges]

    There has been a lot of talk recently about yield curve inversions and whether that means a recession is on the way, and how soon? And if there is a recession, will there also be a bear market? I decided to forget about economic forecast and just look at how the SPX did after a curve inversion. I looked at both the 2yr/10yr and the 3mo/10yr combinations. For the study I used Norgate Data, and
