  • Chapter 13 Summary [Meb Faber]

    This excerpt is from the book Global Asset Allocation now available on Amazon as an eBook. If you promise to write a review, go here and Ill send you a free copy. – I would classify both my mother and grandmother as traditional Southern cooks. Their style was very much of the finger variety. While they may have a broad recipe to go by, the food usually
  • Quantifiable Edges CBI Reaching Bullish Levels [Quantifiable Edges]

    One indicator starting to give bullish readings is the Quantifiable Edges Capitulative Breadth Index (CBI). It reached 8 at the close on Thursday. While 10 is the level I often refer to as a very strong bullish indication, levels as low as 7 or 8 have often been followed by market bounces when the market has been in a long-term uptrend. Below I have produced a table showing results if you entered
  • Generalising the Mojito Strategy [John Orford]

    The Mojito uses a step function to switch up allocations between the VXX and VXZ ETFs over time. A bunch of rules which says… If the spot VIX to VXV (3 month VIX future) ratio ('IVTS') is lower than 0.91 then short the VXX (short term VIX future ETF) and weight by -0.7, while long the VXZ by 0.3; and so on… Each dot on
  • The Mechanics and Dynamics of a Short Squeeze [Factor Wave]

    In a recent post I discussed how the short borrow rate could be used as a predictor of future stock returns. This prompted a reader to ask if the analysis had taken short squeezes into account. This is a good point. Because of the mechanics of short selling it is sometimes not possible to hold short positions as long as we would like. I don't think the study did completely account
  • Margin Debt Bad or Beautiful? [Jay On The Markets]

    Well here I go again breaking one of my own cardinal rules again i.e., being critical of someone elses writing. Must be getting cranky in my old age. Anyway, I recently read an article calling margin debt an indicator that predicts nothing. No the writer is actually technically correct for the most part. Still this sort of surprised me as I remember learning from Norman Fosback

  • P/E Attention Strategies Earn Monthly Excess Return of 1% [Alpha Architect]

    Active investors with limited attention and capital constraints use fundamental metrics to screen and sort potential investments. Price-earnings (P/E) ratios are extremely popular, and are typically calculated using four trailing quarters of net income. Changes in the rankings of published P/E ratios may influence investor attention and subsequent excess returns. From 1974-2013, decile
  • Carry: An Investing Framework [Factor Wave]

    People generally compartmentalize their knowledge. They try to think of things in terms of categories and frameworks rather than remember a bunch of disconnected facts. For example, chemists think of the world in terms of interactions between elements, astrologists (a.k.a stupid people) think of the world in terms of zodiac signs and at FactorWave we think of investing in terms of facto
  • SPX Strangle – High Loss Threshold – 66 DTE [DTR Trading]

    This post looks at selling one-lot options strangles on the S&P 500 Index (SPX), initiated at 66 days-to-expiration (DTE). The results in this post were derived from more than 2300 individual trades entered by the backtester. For background on the setup for the backtests, as well as the nomenclature used in the charts and tables below, please see the introductory article f
  • Add Junk Bonds To The Growing Pile Of Concerns [Dana Lyons]

    This weeks Charts Of The Day and blog posts have had a heavy bearish bent to them. That isnt by design. We just go where the data leads us and much of the data, in our view, is skewing to the bearish side for equities. Included in the concerning assortment of data are many examples of weakening stock market internals. That isnt the only concern, however. As todays Chart Of The Day i

  • Multiple Time Frames for Scoring ETF Rotational Strategies [Alvarez Quant Trading]

    Today we have a guest post from David Weilmuenster who I worked with while at Connors Research. A widely applied technique for scoring assets in rotational systems is to rank those assets by their price momentum, or return, over a given historical window and to rotate into the assets with higher momentum. This approach seeks to capitalize on the well-demonstrated tendency f
  • Market timing with Value and Momentum [Alpha Architect]

    Yesterday we wrote a post showing a potential way to time the market using valuation-based signals. In the past we have also examined how to use momentum-based signals (moving average rules and time-series momentum) to time the market. A natural question is what happens when we combine the valuation-based signals with the momentum-based signals? Here at Alpha A
  • White Noise and Random Walks in Time Series Analysis [Quant Start]

    In the last article of the Time Series Analysis series we discussed the importance of serial correlation and why it is extremely useful in the context of quantitative trading. In this article we will make full use of serial correlation by discussing our first time series models, including some elementary linear stochastic models. In particular we are going to discuss White
  • New Academic Research: ECB predicts stock market using social data [MKTSTK]

    The European Central Bank just released a research report that might be of some interest to readers of this blog. It turns out that Social Data can be useful in predicting the stock market (go figure!): Quantifying the effects of online bullishness on international financial markets [ECB] In our work, we develop a simple, direct and unambiguous indicator o
  • Fractal mathematics used to explain #14 – Momentum Effect in stocks [Quantpedia]

    Mandelbrot has significantly contributed in many ways to the area of finance. He was one of the first who criticized the oversimplifications centered around the early stochastic process models of Bachelier utilizing normal distribution. In his view, markets were fractal and much wilder than classical theory suggests. Additionally, he was a profound critic of the efficient markets hypoth

  • Eureka! A Valuation-Based Asset Allocation Strategy that Might Work [Alpha Architect]

    Weve had a few posts showing that asset allocation systems relying on market valuation indicators (e.g., Shiller CAPE ratios) as a timing signal may end up in disappointment Can market Valuations Be Effective Market-Timing Signals? Dissecting Goldmans 99 Percentile Market-Timing Signal Nonetheless, weve continued on the quest to improve tactic
  • Systems building – execution [Investment Idiocy]

    People often get systematic and automated trading mixed up. The latter is a subset of the first. You can't have a system which is fully automated if it relies on discretionary input, no matter how small. But you can have a system which needs a human to make it run, even though there is no discretion, and its fully systematic. The main area where humans are often used with s
  • Short Rates as a Predictor of Stock Returns [Factor Wave]

    In order to sell a stock short you first need to borrow it from someone else. The way that this typically happens is that your broker takes it from another clients account and loans it to you. You can then sell it to someone else. Although this means you end up with cash in your account, individuals typically don't receive interest for this. In fact they normally pay the broker a fee. (

  • High Conviction Buybacks [Investor’s Field Guide]

    Large U.S. companies spent nearly half a trillion dollars on net buybacks (cash spent on buybacks less cash raised through issuance) during the 12 months ending 6/30/2015. Thats almost as much as the buyback peak in 2007, which didnt turn out too well. Scary! But hold on. Something that gets lost beneath this broader trend is the level of conviction that the companies r
  • The Price Factor [Factor Wave]

    Stock splits lower the stock price. But what does that mean? Most straightforwardly, do lower price stocks perform better than higher priced stocks? Soosung Hwang and Chensheng Lu examined this and published their results in the paper, "Is Share Price Relevant?". They used survivor-adjusted data for the major US exchanges from 1963 to 2006 and each year formed portfolios co
  • Daily Academic Alpha: Why Women Should make MORE than Men… [Alpha Architect]

    As the proud father of 3 kids (to include 2 daughters), this set of papers, while a bit off the wall, made me smile a bit. In short, there seems to be a negative relationship between women and lawsuitsthe more women surround an organization, the less legal trouble the organization faces. It would be great if the relationship was 100% causal, but the data dont
  • Active Investment Managers and Market Timing [CXO Advisory]

    Do active investment managers as a group successfully time the stock market? The National Association of Active Investment Managers (NAAIM) is an association of registered investment advisors. NAAIM member firms who are active money managers are asked each week to provide a number which represents their overall equity exposure at the market close on a specific day

You can download it here. The big take away is the introduction of a new co-movement measure called the Gerber Statistic, which is designed to be more
  • Daily Academic Alpha: Fresh Evidence on the Fama French 5-Factor Model [Alpha Architect]

    The past few weeks weve highlighted a set of research papers that go back and forth on the validity of the Fama and French 5-factor model. A sampling of the research: The Fama French 5-Factor Paper The Kewei, Xue, and Zhang (KXZ) 4-Factor Paper (critically assesses the FF 5-factor model) Cakici investigates the FF 5-Factor Internation
  • A New Factor: Illiquidity [Factor Wave]

    Value, size and low volatility "anomalies" have been studied for decades. Momentum has only been recently recognized by academics but a lot of practitioners have been firm believers in it for many years. Quality is the most recent of the well accepted factors but the components that go into its calculation are well accepted measures of what makes a business good. But we, and a large gro
  • A Diverse Momentum System Using Vanguard Allocation Funds [Scott’s Investments]

    One of the criticisms of momentum systems is they are prone to crashes when momentum reverts. The system highlighted in this article can be implemented using any number of life style or target-risk funds or ETFs. The system chooses from a small number of funds that reflect a range of asset allocation models. The purpose is to employ a diverse, momentum-based asset allocation system.
