  • A Down Day After A Persistent Upmove To New Highs [Quantifiable Edges]

    One compelling study from last nights Quantifinder suggested the recent persistent upmove is unlikely to abruptly end. (This is a theme we have seen many times over the years.) It considers what happens after the market moves up at least 5 days in a row to a 50-day high, and then pulls back. I have updated the stats in the table below. 2018-01-11 We see here a decent edge that becomes stronger

  • How to turn a losing strategy to a winning strategy with commissions [Alvarez Quant Trading]

    A mean reversion strategy I trade was developed with another researcher. This strategy enters on a further intraday weakness with a limit order and typically exits a few days later when the stock bounces. Recently this researcher sent me and email saying Try the strategy as a day trade. Enter at the open and exit at the close. Surprisingly good results. Of course, this peaked my interest and
  • Why You Need Independent Verification of Strategy Results [Allocate Smartly]

But maybe the most important function we serve is simply independent verification of
  • How Bad Are False Positives, Really? [Alex Chinco]

    Imagine youre looking for variables that predict the cross-section of expected returns. No search process is perfect. So, as you work, you will inevitably uncover both tradable anomalies as well as spurious correlations. To figure out which are which, you regress returns on each variables that you come across: \begin{equation*} r_n = \hat{\alpha} + \hat{\beta} \cdot x_n + \hat{\epsilon}_n

  • The Value Effect and Macroeconomic Risk [Alpha Architect]

    It has been well-documented that value stocks have provided higher expected returns than growth stocks. However, there is a great debate about the source of that premium: Is it risk-based or is it related to behavioral errors that create persistent mispricings? There are many papers presenting arguments on both sides. Hence the debate. Cathy Xuying Cao, Chongyang Chen and Vinay Datar contribute to

    Near-perfect neutral month for the State of Trend Following index to close the year just in negative double-digit territory. 2017 was not the best year for the strategy.

  • Levered ETFs for the Long Run? [Flirting with Models]

    We believe that capital efficiency should remain a paramount objective for investors. The prudent use of leverage can help investors employ more risk efficient portfolios without necessarily sacrificing potential returns. Many investors, however, do not have access to leverage (be it via borrowing or derivatives). They may, however, have access to leverage via Levered ETFs. Levered ETFs are often

  • Historical Results Following 4 Up Days To Begin A New Year [Quantifiable Edges]

    The simple fact that the SPX posted a gain on the first 4 days of the year is a pretty rare occurrence, with 2018 only being the 9th instance since 1961. While instances have been low, the intermediate-term performance following such strong starts to the year has been impressive. And looking at most timeframes from 50 days to 250 (or more) days, the returns have been strong. Below is the list of

  • Beyond Excess Returns: How to Enhance Sentiment Strategies using MSCI Barra Risk Models [Raven Pack]

Excess returns: Ignores several risk factors For simplicity, researchers often use excess returns when evaluating the efficacy of a trading
  • Predicting Stock Returns Using Firm Characteristics [Alpha Architect]

    A few weeks ago, we did a deep dive into the factors versus characteristics debate. One of the reasons weve brought up this debate is due to the fact that factor loadings (from regressions) are arguably not as helpful as portfolio characteristics. In other words, knowing a portfolio P/E ratio is more informative for forecasting expected returns than knowing the HML factor loading is .6.

  • A novel capital booster: Sports Arbitrage [EP Chan]

    As traders, we of course need money to make money, but not everyone has 10-50k of capital lying around to start one's trading journey. Perhaps the starting capital is only 1k or less. This article describes how one can take a small amount of capital and multiply it as much as 10 fold in one year by taking advantage of large market inefficiencies (leading to arbitrage opportunities) in the
  • All About the Exits Revisited [Throwing Good Money]

    Back in June of 2016, I wrote this post about random entries and trailing exits. It turns out (on average) that you can beat buy-and-hold of the S&P 500 by simply buying members of the S&P 100 randomly, as long as you a) have a market-timing filter, and 2) have a trailing stop of 20%. Yes thats right, just pick them at random! Here are the details of that original system (its
  • Can the January effect be exploited in the market? [Mathematical Investor]

    The January effect, in common with the Halloween indicator and sell in May and go away, is a catchy, get-rich-quick investment idea adored by financial commentators because it is so easy to explain to unsophisticated readers. It rests on the claim that the U.S. stock market performs better in January, compared to the other months in the year. Unfortunately, financial reports

  • Deep Learning Insights for Factor Investing [Quantpedia]

    Deep learning is an active area of research in machine learning. I train deep feedforward neural networks (DFN) based on a set of 68 firm characteristics (FC) to predict the US cross-section of stock returns. After applying a network optimization strategy, I find that DFN long-short portfolios can generate attractive risk-adjusted returns compared to a linear benchmark. These findings underscore

    In statistics, the null hypothesis is the default statement that you test with data. From this test, you can either reject the null hypothesis in support of an alternative or assert that there is not enough evidence to believe anything other than the null hypothesis with a certain degree of confidence. In an industry driven by speculation and talking heads pushing the next hot investments, an

  • Mean Reverting and Trending Properties of SPX and VIX [Relative Value Arbitrage]

    In the previous post, we looked at some statistical properties of the empirical distributions of spot SPX and VIX. In this post, we are going to investigate the mean reverting and trending properties of these indices. To do so, we are going to calculate their Hurst exponents. There exist a variety of techniques for calculating the Hurst exponent, see e.g. the Wikipedia page. We prefer the method
  • Best of Research Review 2017 [Capital Spectator]

    So many research papers, so little time. How do you separate the wheat from the chaff? You might start with the following five economic and financial papers that appeared in The Capital Spectators Research Review column in 2017. In a sea of newly minted studies over the past 12 months, these titles stand out as worthy of a second read. Time-Varying Risk Premiums and Economic Cycles Thomas
  • The Tax Efficiency of Long-Short Strategies [Alpha Architect]

    Conventional wisdom can be defined as ideas that are so accepted that they go unquestioned. Unfortunately, conventional wisdom is often wrong. Two great examples are that millions of people once believed the conventional wisdom that the Earth is flat, and millions also believed that the Earth is the center of the universe. Much of todays conventional wisdom about investing is also wrong. The
  • Persistance in Cryptocurrencies [Quantpedia]

    This paper examines persistence in the cryptocurrency market. Two different longmemory methods (R/S analysis and fractional integration) are used to analyse it in the case of the four main cryptocurrencies (BitCoin, LiteCoin, Ripple, Dash) over the sample period 2013-2017.
