  • Unsupervised candlestick classification for fun and profit part 2 [Robot Wealth]

    In the last article, I described an application of the k-means clustering algorithm for classifying candlesticks based on the relative position of their open, high, low and close. This was a simple enough exercise, but now I tackle something more challenging: isolating information that is both useful and practical to real trading. Ill initially try two approaches: Investigate whether there are
  • Searching for an Efficient Market Regime Filter [Helix Trader]

    The probability of our long term success as traders increases when we trade with the prevailing market trend. This means when trading stocks we should be buying when the overall market is rising and / or shorting when the overall market is falling.

  • Trading Autocorrelation? [Quintuitive]

    Markets are very smart in absorbing and reflecting information. If you think otherwise, try making money by trading. If you are new to it, make sure you dont bet the house. In other words, markets are efficient. At least most of the time. So then why people trade? The general believe is that there are windows during which prices of certain assets are inefficient. Thus, there are opportunities
  • Can We Tell Who Trades on Which Dark Pools? [Mechanical Markets]

    Marketplace transparency ensures that investors receive a fair price and have accurate data to conduct their research. But, transparency can also make it harder for traders to conceal their intentions from competitors and counterparties.

  • Review: Inovance’s TRAIDE application [QuantStrat TradeR]

    This review will be about Inovance Tech's TRAIDE system. It is an application geared towards letting retail investors apply proprietary machine learning algorithms to assist them in creating systematic trading strategies. Currently, my one-line review is that while I hope the company founders mean well, the application is still in an early stage, and so, should be checked out by potential
  • CDS Inferred Stock Volatility [MathFinance.cn]

    I have written a working paper on CDS (credit default swap) implied stock volatility and found some interesting results. Post it here just in case someone is interested. Both CDS and out-of-money put option can protect investors against downside risk, so they are related while not being mutually replaceable. This study provides a straightforward linkage between corporate CDS and equity option by

  • Correlation and correlation structure (3), estimate tail dependence using regression [Eran Raviv]

    What is tail dependence really? Say the market had a red day and saw a drawdown which belongs with the 5% worst days (from now on simply call it a drawdown): weekly SPY returns One can ask what is now, given that the market is in the blue region, the probability of a a drawdown in a specific stock? We all understand the concept of beta of a stock with respect to the market, the sensitivity of a
  • Momentum On Dual Momentum Portfolios [Quants Portal]

    In the first section, this article describes a Dual Momentum study over an iShares country etfs basket with a new attempt to improve this well-known investing style. I chose iShares because it is the world largest family of Exchange Traded Funds (ETFs) from BlackRock. Although different stock markets correlations have become weaker and weaker in these last 10 years, this article easily shows that
  • Hi-Lo Index as a Market Timing Indicator [Alvarez Quant Trading]

    My strategies use a market timing indicator to tell me when I should not be trading the strategy. The blog post, Avoiding Stock Market Crashes with the Hi-Lo Index of the S&P500, presented a very simple idea of using new highs vs new lows. The post tests trading the SPY & IEF but I wanted to know how well would it work on a S&P500 mean reversion strategy. The Indicator The Hi-Lo Index
  • Valuation Metrics In Perspective [Larry Swedroe]

    Its well-established in the literature that valuation metricssuch as the dividend yield (D/P) and the earnings yield (E/P), as well as its cousin, the Shiller CAPE 10provide important information in terms of future expected returns. In fact, these metrics are the best that investors have for predicting long-term equity results. For instance, the Shiller CAPE 10, a cyclically adjusted
  • Pros and Cons of New Technology-enabled Indexes [CXO Advisory]

    What are pros and cons of extending the definition of financial index beyond conventional market capitalization (buy-and-hold) weighting? In the October 2015 draft of his paper entitled What Is an Index?, Andrew Lo proposes that any portfolio satisfying three properties should be considered an index: (1) transparent (public and verifiable); (2) investable (realistic and liquid benchmark);
  • Deconstructing the Time-Series Momentum Strategy [Quantpedia]

    Moskowitz, Ooi, and Pedersen (2012) show that time series momentum delivers a large and significant alpha for a diversified portfolio of various international futures contracts over the 1985 to 2009 period. Although we confirm these results with similar data, we find that their results are driven by the volatility-scaled returns (or the so-called risk parity approach to asset allocation) rather

  • Random data: Evaluating [Investment Idiocy]

    Everyone hates drawdowns (those periods when you're losing money whilst trading). If only there was a way to reduce their severity and length…. Quite a few people seem to think that "trading the equity curve" is the answer. The basic idea is that when you are doing badly, you reduce your exposure (or remove it completely) whilst still tracking your 'virtual' p&l
  • I bought corporate bonds and all I got was this stupid currency exposure [Flirting with Models]

    Summary In the current Fed on / Fed off market environment, dollar exposure matters Currency hedged exposures have exploded in popularity in the equity space Using the experience of Canadian investors, we demonstrate the large impact that currency can have on fixed income Investors buying global bonds should consider whether currency hedging makes sense for them Currency hedging remains a
  • Making Time (Even More of) an Investor’s Best Friend [EconomPic]

    Ben Carlson of A Wealth of Common Sense blog (and author of a great book by the same name), had a recent post Playing the Probabilities outlining that time has been an investor's best friend (for those investors that have had in some cases quite a bit of time), pointing to the following table. He also shared some pretty amazing stats, including: The worst total return over a 20 year period
  • How Monday s Strong Drop May Be Setting SPX Up For A Bounce [Quantifiable Edges]

    When a market has already sold off for multiple days and the selling accelerates that can often mark a point where a bounce becomes likely. Mondays selling triggered the Quantifinder study below.

  • Dividends An Illogical Preference [Larry Swedroe]

    A large body of literature examines whether managers of actively managed funds add value to their investors by generating abnormal returns. Unfortunately, not only do the vast majority fail to do so, but the evidence, as presented in my book, The Incredible Shrinking Alpha, demonstrates that the already-small percentage of managers able to beat their benchmarks has been diminishing at a
  • Screening Using False-Discovery Rates [Alex Chinco]

    1. Motivating Example Jegadeesh and Titman (1993) show that, if you rank stocks according to their returns over the previous 12 months, then the past winners will outperform the past losers by 1.5{\scriptstyle \%} per month over the next 3 months. But, the authors dont just test this particular strategy. They also test strategies that rank stocks over the previous 3, 6, and 9 months and
