    The existence of a quality premium in stocks that has been persistent over time, pervasive around the globe, and robust to various definitions have been well documented by studies such as Buffetts Alpha, Global Return Premiums on Earnings Quality, Value, and Size, and The Excess Returns of Quality Stocks: A Behavioral Anomaly. While there is no consistent definition of
  • Why is data cleaning important and how to do it the right way? [Quant Insti]

    Data cleaning is the time-consuming but the most important and rewarding part of the data analysis process. The process of data analysis is incomplete without cleaning data. But what happens if we skip this step? Suppose we had certain erroneous data in our price data. The incorrect data formed outliers in our dataset. And our machine learning model assumed that this part of the dataset (maybe the
  • New Research Tries To Solve For Beta Risk s Failure For Stocks [Capital Spectator]

    At the core of modern finance is the proposition that beta (market) risk is the dominant factor that drives performance.

  • Fundamental and Sentiment analysis with different data sources [Quant Insti]

    Technical analysis of price and volume history wont cut it alone nowadays.

We want fundamental data in the form of ratios, financial statements, earnings, etc. On top of that we can also use

  • The Importance Of Stress Tests & Robustness Tests 10/12 [Trade With Science]

  • Macro uncertainty as predictor of market volatility [SR SV]

  • The Amazing Efficacy of Cluster-based Feature Selection [EP Chan]

    One major impediment to widespread adoption of machine learning (ML) in investment management is their black-box nature: how would you explain to an investor why the machine makes a certain prediction? What's the intuition behind a certain ML trading strategy? How would you explain a major drawdown? This lack of "interpretability" is not just a problem for financial ML, it is a
  • Is the Market Getting more Efficient? [Alpha Architect]

  • Copula for Pairs Trading: A Detailed, But Practical Introduction [Hudson and Thames]

    Suppose that you encountered a promising pair of stocks that move closely together, the spread zig-zagged around 0 like some fine needle stitching that sure looks like a nice candidate for mean-reversion bets.

Results are net of transaction costs (see backtest assumptions). Learn about what we do and
  • Extracting Interest Rate Bounds from Option Prices [Sitmo]

    In this post we describe a nice algorithm for computing implied interest rates upper- and lower-bounds from European option quotes.

  • Historical Returns for Newly Elected Presidents [Quantifiable Edges]

    Back in the 1/20/2009 blog I looked at inauguration day returns. I wondered at the time whether a new president brought about new hope and optimism for the market. I have decided to update that study today. I limited the instances to only those inaugurations where a new president was entering office.
