This post will demonstrate the PELT algorithm from the changepoint package–a competing algorithm to the twitter package’s breakout detection algorithm. While neither of these algorithms produce satisfactory results, one change point location approximation algorithm that makes no distributional

nvestors trying to make decisions on how to invest their savings face many complications that are frequently ignored in research papers on asset allocation. Often, it is assumed that a fixed lump sum of money is invested. But this is rarely the case in real world investing for the individual

I’ve previously touched on the use of social media analytics as one useful measure of investor sentiment. It does occur to me that it might be interesting to explore a particular source of such analytics. This could be of service by making the concepts more tangible and by illustrating the growth

In the first part of this three-part series, What Drives Real GDP Growth?, I identified four themes which drive real GDP growth. These themes are based on 19 socioeconomic indicators whose average Spearman and Pearson correlations to real GDP growth were statistically significant and greater than

I actually received a large volume of what could best be chararcterized as “hate mail” for one of the previous posts on percentile channels. In reading these comments I was reminded of Jimmy Kimmel’s funny segments where celebrities read mean tweets about themselves. While I did not publish

In this post I’d like to show an example of constructing a monthly-rebalanced long-short portfolio to exploit alpha signals while controlling for factor exposures. This example covers the time period between March 2005 and 2014. I use 477 stocks from S&P500 universe (data source: Quandl) and

We have already shown before how to set up CUDA in both Windows and Linux environment and how to create a simple project. Today we will demonstrate how easy it is to perform a simple Monte Carlo simulation using Thrust library. We will do so by estimating π with random numbers. From the

Based on psychology theory, we propose that intuition can be a key element stimulating auditor skepticism, whereas overreliance on analytical processing can overwhelm auditors’ intuition thereby reducing skepticism. We test our expectations with an experiment containing responses from 85 senior

Some trading strategies make intuitive sense. Other trading strategies do not. With some trading strategies it is possible to articulate some logical reason or reasons regarding why they might be expected to work well over time. With others trading strategies, well, not so much.

Last year Rowan spoke about the importance of consistency in portfolio construction and today I'd like to expand on the concept a little. There are a number of reasons why consistency is important: 1) our performance pegged pricing structure is based on consistency 2) it's psychologically

Is proximity to doom good or bad for the stock market? To measure proximity to doom, we use the “Doomsday Clock” “Minutes-to-Midnight” metric, revised occasionally via the Bulletin of the Atomic Scientists, which “conveys how close we are to destroying our civilization with dangerous

Dual momentum with Value and Momentum factor portfolios was tested back to 1950 with 16% annual returns: What is the tracking error of real ETFs to those portfolios? Vanguard Small-Value (VBR) launched in 2004 and can underperform Value near market peaks … Continue reading

Recently we have highlighted the value of using social data in your analysis of the market. Earlier we showed how you could have used Google Trends to price ZNGA after its IPO. We also showed how you can monitor risk with the Twitter stream. Today we will expand upon an example where we showed how

Some mutual funds purchase stocks before dividend payments to artificially increase their dividends, which we call "juicing." Funds paid more than twice the dividends implied by their holdings in 7.4% of fund-years examined. Juicing is associated with larger inflows, and is more common

A couple of weeks ago, I had the pleasure of a short correspondence with Lars Kestner, a well known quant and derivatives trader, and creator of the thoughtful K-ratio as a measure of risk adjusted performance. We connected on the definition of alpha, and how the term has been so abused in media and

In the last Forex Trading Diary Entry (#1) I described how to build an automated trading system that hooks into the OANDA forex brokerage API. I also mentioned that the next steps included constructing a portfolio and risk management overlay for all suggested signals generated by the Strategy

Starting with this post, and spanning the next seven or eight posts, I will show the backtest results for dynamic exits of 38 days-to-expiration (DTE) Iron Condors (IC), with different delta short strikes. In this post I wills show the results for the 8 delta short strike 38 DTE versions. For some

We examine whether the predictability of future returns from past returns is due to the market's underreaction to information, in particular to past earnings news. Past return and past earnings surprise each predict large drifts in future returns after controlling for the other. Market risk,

Note: I’m holding a cover design contest for my new book out next week, feel free to enter! This is normally something I would send to The Idea Farm, but since we started the conversation here I wanted to follow up. One of the best parts of writing is getting feedback. I posted an article the

January started the year as strong — if not stronger — than last year for trend following. Keeping the momentum going, and profiting from a continuation in a few big trends (US Dollar Index, Energies or Swiss Bonds for instance), the index opens the year with a double-digit positive monthly

James Picerno of Capital Spectator recently did a good review of Error-Adjusted Momentum in his post “A Momentum-Based Trading Signal with Strategic Value“. The Capital Spectator blog is rich with great content covering a diverse range of subjects from economics to asset allocation and

I’ve been working at The University of Manchester for almost a decade and will be leaving in just less than 3 weeks time! A huge part of my job was to support a major subset of Manchester’s site licensed application software portfolio so naturally I’ve made use of a lot of it over the years.

I have been asked to join a live discussion panel ​being put on by TimingResearch​. Each week, TimingResearch surveys a large group of traders to get their thoughts about current market conditions. TimingResearch then produces a report based on the survey.

Part 3 of this series demonstrated how to train a HMM on a toy model, this post will focus on how to actually go about modelling real life data. A trend following strategy will be developed for trading the S&P 500. In most machine learning classification problems you need a set of training data

The January Barometer is a fairly famous study from the Stock Traders Almanac. It says that “as goes January, so goes the year”. In other words, a positive January will typically lead to a positive year, while a negative January can be a warning. Let’s look at how the SPX has done for the

Scott’s Investments provides a daily Ivy Portfolio spreadsheet to track the 10 month moving average signals for two portfolios listed in Mebane Faber’s book The Ivy Portfolio: How to Invest Like the Top Endowments and Avoid Bear Markets. Faber discusses 5, 10, and 20 security portfolios that

We have been thinking a lot about winning streaks lately. Looking at charts of the S&P 500 index it is hard not to be impressed by how many positive monthly returns we have had since the “resolution” of the last full-blown Euro crisis in mid-2012. We wanted to gain some historical

So recently, I tried to combine Flexible and Elastic Asset Allocation. The operative word being–tried. Essentially, I saw Flexible Asset Allocation as an incomplete algorithm — namely that although it was an excellent method for selecting securities, that there had to have been a better way to

Reading old investment books is somewhat of a hobby of mine (I know probably need a better hobby). Glancing up on my bookshelf there are titles most have never heard of such as Once in Golconda, The Zurich Axioms, and Supermoney. I was flipping through another book new to me that I found when

We examine the relation between a measure of male CEOs’ facial masculinity and financial misreporting. Facial masculinity is associated with a complex of masculine behaviors (including aggression, egocentrism, risk-seeking, and maintenance of social status) in males. One possible mechanism for

We have corrected the Momentum Strategy winners list for January 2015 (to be held during February 2015). The third place winner was incorrect due to omission of a dividend.

Friday is the last trading day of January. The first day of the month is well known for having a seasonal bullish tendency. Interestingly, I have noted this tendency has not been prevalent over the last few years. This can be seen in the equity curve below.

Recently, volatility has been on the up. Generally, we associate rising volatility with a bear regime, but we also know there is a percolating oil shock. Is the volatility we see in the stock market broad-based, or is it the effect brought about by sharp the drop in oil prices (so related to the

In part 1 and 2 of our volatility series I discussed a technique that I've developed to monitor broad market volatility with a Synthetic Volatility Index. Today I'm going to quantify our index by applying it to a liquid universe of equities as a simple entry filter. If volatility indeed
