  • Go Skew Yourself with Managed Futures [Alpha Architect]

    Skewness is a statistical measure of how returns behave in the tails of a probability distribution. Wikipedia has a more robust definition of skewness with some good visuals here. If an investment (e.g., stocks) has negative skewness this means that the extreme returns are more likely to be negative than positive (it has a tendency to crash). However, if its return has a positive skewness (e.g.,

But the exact
  • Webinar: Alpha Generation 01/10/2017 [Portfolio Effect]

    Asset returns based on low frequency prices (e.g. end-of-day quotes) are still dominating modern portfolio analysis. To make portfolio metrics more relevant intraday and improve the precision of estimates, new data frequency needs to be explored. In this presentation we demonstrate how using high frequency market data for portfolio risk management and optimization could improve the classic
  • The Laguerre RSI vs Classic RSI [System Trader Success]

    John Ehlers is a name youll run across when you start your journey into testing various indicators and filters to be used in your trading models. I remember reading about the Laguerre Filter and Laguerre RSI many years ago when they first appeared on the scene. At the time I was not nearly into quantitative trading as I am today. So lets take a closer look at the Laguerre RSI and answer a

  • Seasonalities in Stock Returns [Quantpedia]

    Existing research has documented cross-sectional seasonality of stock returns the periodic outperformance of certain stocks relative to others during the same calendar month, weekday, or pre-holiday periods.

  • Writing Puts, Or Just Pretending To [Throwing Good Money]

    Which color do you like better? Green or brown? Im partial to the green curve myself. That green curve comes from writing putssort of. Writing puts can be a lower volatility play that makes you money in choppy or flat markets, falls more softly in down markets, and seriously under-performs when the market goes on a tear upward. Whats a put and where do you put them? If youre an

  • Site News: Dabbling in Ads and Where All the Clicks Went in 2016 [Quantocracy]

    Two bits of site news: First, after 4+ years of running this site mostly gratis, Ive decided to dabble in adding advertisements, so expect to begin seeing the first baby steps with a handful of ads from Google.

Site News: Dabbling in Ads and Where All the Clicks Went in 2016

Two bits of site news:

First, after 4+ years of running this site mostly gratis, I’ve decided to dabble in adding advertisements, so expect to begin seeing the first baby steps with a handful of ads from Google. I’ve tried to keep the ads as unobtrusive as possible and my hope is that your reading experience will be essentially unchanged.

On to more fun news, here’s an updated view of where the all the clicks on the mashup went in 2016. The numbers include any site that received at least 500 clicks, but ignore our Twitter, Stocktwits and daily RSS/Email.

I’ve labeled the top 10 recipients. The number in parenthesis represents the number of links we carried from that site, and the % represents the portion of all clicks that that site received.

Alpha Architect remains the top dog at 7.1% of clickthroughs (how they maintain their amazingly consistent publishing schedule I’ll never know).

We’re casting a wide net though. The top 10 recipients together only received about 35% of total clickthroughs. A whopping 117 sites received at least 500 clickthroughs for the year. I’m happy with that. The goal of Quantocracy is to improve not just the quality of work in the quantitative blogosphere (read more), but the quantity as well.

At no point in history has so much good work on these subjects been shared so freely. To all of the denizens of Quantocracy: a big mahalo, gracias, 謝謝 and thank you for helping this community to grow.

And finally, the 5 most clicked links of the year:

  1. Machine learning for financial prediction: experimentation with Aronson’s work – part 1 [Robot Wealth]
  2. Machine learning for financial prediction: experimentation with Aronson’s work – part 2 [Robot Wealth]

  • Trend Following UP in December, Down in 2016 [Wisdom Trading]

    December 2016 Trend Following: UP +1.38% / 2016: -18.15% December closed 2016 on a slight positive note, avoiding six straight months of negative returns for our State of Trend Following index. An inflection point was felt in the markets towards the close of the year, but this was obviously not enough to offset what has been a strong under-performance in the second half of the year. The first half

  • A Modern, Behavior-Aware Asset Allocation [Flirting with Models]

    Happy New Year! To kick off the year, we want to share a white paper we penned mid-December containing our views on building a modern strategic asset allocation. The white paper covers: Why we believe tailwinds from the last 30 years are turning into headwinds for traditionally allocated stock-bond portfolios. Why the normative optimal portfolio may not be the optimal achievable portfolio and the
  • Using Trend-Following Rules to Enhance Factor Performance [Alpha Architect]

    After reviewing the 2016 performance of trend-following (-18.15%), its unclear why anyone would mention the word trend following in a public forum. But well give it a whirl anyway The comedian Victor Borge once famously observed, Santa Claus has the right idea visit people only once a year. In studying investment markets, many have taken a similar approach, preferring a
  • The Bayesian Information Criterion [Alex Chinco]

    Imagine that were trying to predict the cross-section of expected returns, and weve got a sneaking suspicion that x might be a good predictor. So, we regress todays returns on x to see if our hunch is right, \begin{align*} r_{n,t} = \hat{\mu}_{\text{OLS}} + \hat{\beta}_{\text{OLS}} \cdot x_{n,t-1} + \hat{\epsilon}_{n,t}. \end{align*} The logic is straightforward. If x explains enough of
  • N-Day exits with Mean Reversion [Alvarez Quant Trading]

    My last post on using PercentRank to measure mean reversion proved very popular. A reader looked at the trades and wondered if it would be best to exit after five days because the average trade with longer holds was a loser. I am surprised I have not covered this topic before. Background Early in while working for Larry Connors, I had done a mean reversion test. I was looking at the trades and
  • State of Trend Following in December [Au Tra Sy]

    Happy new year to all readers! With best wishes for your trading in the coming twelve months, which Im sure youll agree will prove interesting from several perspectives.

  • 38 DTE Iron Condor Results Summary – Part 2 [DTR Trading]

    In the last post, 38 DTE Iron Condor Results Summary, I showed the backtest results from 97,416 iron condor (IC) trades.

  • Demystifying the Hurst Exponent Part 2 [Robot Wealth]

    What if you had a tool that could help you decide when to apply mean reversion strategies and when to apply momentum to a particular time series? Thats the promise of the Hurst exponent, which helps characterise a time series as mean reverting, trending, or a random walk. For a brief introduction to Hurst, including some Python code for its calculation, check out our previous post. Even if you

So this year, Ill be posting a lot more research and will start the year off by exploring momentums robustness.

  • Are Commodities Still a Good Portfolio Diversifier? [Dual Momentum]

    Overfitting the data is a serious problem when constructing financial models. One way to guard against this is to have lots of data. This helps you determine if your results are robust by seeing how they hold up over different time periods. But this assumes the underlying market dynamics remain stable over time. That is not always the case. Gogi Gerwal gives a good example of how you may be misled
  • Wakey, Wakey: Trends in Active Fund Pre-Fee Excess Returns [Basis Pointing]

    In a recent posting, I compared the prices of US active mutual fund to estimates of future pre-fee excess returns. In summary, I found that the annual expenses of most active funds met or exceeded a generous estimate of their potential before-fee excess returns. That is, many funds look like theyre priced to fail. What I didnt include in that posting, though, was detail on how I derived

  • “Matt s Breadth Indicator” Update [Throwing Good Money]

    Happy new year! Its that time again, when everyone with a blog does a wrap up of the previous year. Heres my look-back. Many of you follow along with the +/-30% per quarter wider-market breadth indicator. Which is too much of a mouthful, so Ive humbly named it after myself instead.
