  • Time series analysis and data gaps [EP Chan]

    Most time series techniques such as the ADF test for stationarity, Johansen test for cointegration, or ARIMA model for returns prediction, assume that our data points are collected at regular intervals. In traders' parlance, it assumes bar data with fixed bar length. It is easy to see that this mundane requirement immediately presents a problem even if we were just to analyze daily bars
  • For The VIX, It s All About The Recovery [Dana Lyons]

    We mentioned in a post yesterday on 90% Down Days that one of the challenges for risk managers is to correctly distinguish a minor market dip from something that is developing into a more serious decline. One potential aid in addressing that challenge comes from the behavior of the S&P 500 Volatility Index, the VIX. As most market observers are likely aware, the VIX tends to rise duri
  • Insuring tomorrow s decline, today [MKTSTK]

    As of pixel time the VIX is up over 7% and the S&P 500 is basically unchanged; we feel this situation arises when traders desire protection today for the possibility of danger tomorrow. In other words, the price of risk is rising and markets are stabilizing. Intuitively (i.e. the feeling our rat brains get from too many years spent scurrying around the markets) we feel this sets the sta
  • The First Academic Paper with a Shotgun Picture in it [Alpha Architect]

    Here is one of the figures in a Journal of Finance paper published in 2013 by N. Garleanu and L Pedersen. The figure depicts various portfolio optimizations under different assumptions and then has a visualization equivalent with hockey players, skeet shooters, and missile systems. Im not sure how many readers follow hard-core academic publications, but this i

  • Bad Breadth Milestone A Warning For Stocks? [Dana Lyons]

    Weve been discussing the weakening market breadth recently, especially as it pertains to New Highs vs. New Lows. Again, our contention is that the more stocks participating in a rally, the healthier the rally is. The most recent example of this weak breadth was Wednesdays post on the fact that Nasdaq New Highs-New Lows have not hit a 52-week high in over 400 days. Today brings another

  • The Decision Moose Asset Allocation Framework [CXO Advisory]

    A reader suggested a review of the Decision Moose asset allocation framework of William Dirlam. Decision Moose is an automated framework for making intermediate-term investment decisions. Decision Moose focuses on asset class momentum, as augmented by monetary policy, exchange rate and interest rate indicators. Its signals tell followers when to switch from one index fund
  • The Market For Lemons : A Lesson For Dividend Investors [Research Affiliates]

    Central banks the world over are buying high-quality bonds, thereby removing them from the market and forcing savers to find alternative strategies to meet their income needs. In this environment of financial repression and near-zero interest rates, dividend-yield (or equity income) investing has become increasingly popular. Investors are understandably reallocating their portfolios fro
  • Estimating Crash-Risk Potential For The US Stock Market [Capital Spectator]

    History shows rather clearly that the stock market is prone to extreme events, aka crashes. The challenge is deciding when the risk for a repeat performance is unusually high. The literature offers endless possibilities, which is a reminder that the market can crumble for any number of reasons. The leading factor, of course, is the business cycle. But internal market issues cant be ign
  • Risk Aversion, Information Choice, and Price Impact [Alex Chinco]

    Kyle (1985) introduces an information-based asset-pricing model where informed traders keep trading until the marginal benefit of holding one additional share of the asset is exactly offset by the marginal cost of this last trades price impact. This model has really nice intuition, but it also has some undesirable features. For instance, traders in Kyle (1985) are risk neutral and don

  • Think MPT Doesn t Work? Clearing Up Some Misconceptions [CSS Analytics]

    I have spent many years toiling with creating different asset allocation methodologies including the application of traditional and non-traditional portfolio optimization. Given the recent flare of articles on this topic in the blogosphere, I felt it was worthwhile to share my two cents. Applying optimization to a tactical approach is a topic that readers may already be familiar with,
  • Backtesting A Cautionary Example [Scott’s Investments]

    My previous article detailed backtest results for the ETFReplay.com portfolio. Aggregate, risk-adjusted results since 2004 were impressive when compared to a 60/40 Vanguard mutual fund. However, results over the past 2-3 years lagged the benchmark. The test below was conducted using Portfolio123 (P123?). It uses a similar ranking system to the ETFReplay 6/3/3 system but
  • Lazy PCA Site Update [John Orford]

  • How to Get a List of all NASDAQ Securities as a CSV file using Python? [Quant at Risk]

We will make use of Python in the Unix-based environment. As you will see, for any text file, writing a single line of Unix commands is more than enough to deliver exactly what we need (a basic text file processing)

    A new working paper from Gennaili, Ma, and the one-the-only Andrei Shleifer. Expectations and Investment Using micro data from Duke University quarterly survey of Chief Financial Officers, we show that corporate investment plans as well as actual investment are well explained by CFOs expectations of earnings growth. The information in expectations data is not sub
  • A Random Ass Kicking of Wall Street [Following the Trend]

    A random number generator can beat your mutual fund. Given a choice between a random portfolio and a mutual fund, Ill go with the randomizer every day of the week and twice on Sundays. You think Im joking? Im not joking. Trashing the mutual fund industry is almost like beating a dead horse. Except of course that its a thriving, multi billion dollar dead horse. Still, po
  • Stops IV: The Trailing Stop [Factor Wave]

    A reader asked if there was any real difference between using a fixed stop at a given distance from our entry price or a trailing stop which we move so it stays a certain distance from the highest amount the investment has made. A trailing stop is a very comforting strategy. It seems to protect us from the painful experience of seeing our winners turn into losers (covered in this post).
  • Will the quants blow up the markets again? [Humble Student of the Markets]

    Josh Brown had a fascinating post which postulated that the quants pose a significant systemic risk to market volatility: Theres an interesting idea going around that asset management specifically the metastasizing quantitative strategies run via black box are where the next big scare is due to come out of. Volatility has been so low, for so long, that winning trades

  • A Conjecture Which Unifies Timing Strategies [John Orford]

    When arrested in Asia (many countries, not everywhere) never step into the station. Once you put a foot inside, there's an unstoppable force pulling you deeper into the bowels of the judicial system. Conviction rates in Japan, Korea and China are 99%+. For comparison, conviction rates are in the 70s in the UK and US. Why?
  • New related paper to #8 – FX Momentum [Quantpedia]
