Quant Mashup Position Sizing for Practitioners - Part 1: Beyond Kelly [Quant Fiction]Albert Einstein once proclaimed that “compound interest is the eighth wonder of the world” (allegedly, at least; people attribute all kinds of sayings to that guy). Let’s just assume that he did. This is the single most important reason why people participate in the markets. The magic of(...) A Different Way To Think About Drawdown — Geometric Calmar Ratio [QuantStrat TradeR]This post will discuss the idea of the geometric Calmar ratio — a way to modify the Calmar ratio to account for compounding returns. So, one thing that recently had me sort of annoyed in terms of my interpretation of the Calmar ratio is this: essentially, the way I interpret it is that it’s a(...) Value Investing Portfolios are Not Dead, But Some Have Done Better than Others [Alpha Architect]Mirror, mirror, on the wall – which is the fairest of them all? Recent commentary (to include a recent Barron’s article) seems to suggest that value is dead and may never come back. Of course, most of these comments revolve around the price-to-book valuation metric, which, as the Barron’s(...)

The Importance of Diversification in Trend Following [Flirting with Models]Diversification is a key ingredient to a successful trend following program. While most popular trend following programs take a multi-asset approach (e.g. managed futures programs), we believe that single-asset strategies can play a meaningful role in investor portfolios.

Equity Factors and Inflation [Factor Research]We recently published a research note on the relationship between factor returns and real GDP growth (Equity Factors & GDP Growth), which highlighted that some factors exhibit pro-cyclical while others have anti-cyclical characteristics.

Two Seasonal Cycles Colliding Suggest A Possibly Volatile Period Ahead [Quantifiable Edges]As we head towards the summer, the stock market has two long-term cycles converging that suggest it could be a rough ride.

Bitcoin Is Not the New Gold [Quantpedia]Cryptocurrencies such as Bitcoin are establishing themselves as an investment asset and are often named the New Gold. This study, however, shows that the two assets could barely be more different. Firstly, we analyze and compare conditional variance properties of Bitcoin and Gold as well as other(...) Economics, finance and pseudoscience [Mathematical Investor]Bloomberg columnist Mohamed El-Erian recently lamented that the discipline of economics “is divorced from real-world relevance and has lost credibility.” Among the problems he mentions currently afflicting the field are the following: The proliferation of simplifying assumptions that lead to an(...) VIX Mean Reversion After a Volatility Spike [Relative Value Arbitrage]In a previous post, we showed that the spot volatility index, VIX, has a strong mean reverting tendency. In this follow-up installment we’re going to further investigate the mean reverting properties of the VIX. Our primary goal is to use this study in order to aid options traders in positioning(...) Fixed income carry as trading signal [SR SV]Empirical evidence for 27 markets suggests that carry on interest rate swaps has been positively correlated with subsequent returns for the past two decades. Indeed, a naïve strategy following carry as signal has produced respectable risk-adjusted returns. However, this positive past performance(...) Are Trend-Following and Time-Series Momentum Research Results Robust? [Alpha Architect]The authors discuss a variety of past research papers on time-series momentum but pay particular attention to the Moskowitz, Ooi, and Pedersen (“MOP”) 2012 JFE paper, “Time Series Momentum.” This paper is arguably the first paper in recent memory to crack the top-tier academic journals with(...)

In the chapter, Dr. Siegel revealed that the simple trend following strategy(...) The Costs of Implementing Momentum Strategies [Alpha Architect]There are now hundreds of factors in what John Cochrane famously called the “zoo of factors.” However, there are only a small number that meet the requirements for investment that my co-author, Andrew Berkin, and I establish in our book, “Your Complete Guide to Factor-Based Investing”:(...) Backtesting Four Portfolio Optimization Strategies In R [Capital Spectator]Investing strategies run the gamut, but every portfolio shares a common goal: delivering optimal results.

Exploring Alternative Price Bars [Black Arbs]This post explores a concept at the heart of quantitative financial research. Most qfin researchers utilize statistical techniques that require varying degrees of stationarity.

Mean Reversion Entry Timing [Alvarez Quant Trading]One of the first tests I did when I got AmiBroker twenty years ago was a mean reversion test. It was a classic set up, a stock in an uptrend, followed by a pullback. But the entry differed from what I do now. The entry waited for a confirmation of the trend back up. The trade would enter when the(...) Crypto-asset Research Survey [CXO Advisory]What is the body of academic research on crypto-assets?

Three-day Pullback Pattern Into Turnaround Tuesday Potentially Bullish [Quantifiable Edges]SPY’s move lower over the last 3 days has set up a potential “Turnaround Tuesday” scenario. The fact that it made a lower high, lower low, and lower close for at least the 3rd day in a row triggered the following study. 2018-04-241 The numbers are impressive and the bounces couldn’t get much(...) There Exist Two Different Accruals Anomalies [Quantpedia]We document that several well known asset-pricing implications of accruals differ for investment and non-investment-related components. Exposure to an investment-accruals factor explains the cross-section of returns better than the accruals themselves, and this factor’s returns are negatively(...) Risk Ignition with Trend Following [Flirting with Models]While investors are often concerned about catastrophic risks, failing to allocate enough to risky assets can lead investors to “fail slowly” by not maintaining pace with inflation or supporting withdrawal rates.

Traders could look at the chart and say it is “short-term oversold” due to the fact that it closed at a 5-day low for the 1st time in a while.

Why My 1994 Low-Vol Dissertation Didn't Make Impact [Falkenblog]Pim van Vliet posted a link to my 1994 dissertation, noting it was an early documentation of the low-vol effect. One may wonder, why did this early evidence fall flat? Clearly, lots of things, but I'll try to highlight the keys. Here's my lead paragraph, which makes clear I saw the low vol(...) Benchmarking, Behavioral Biases, and the March Madness Tournament Challenge Recap [Flirting with Models]Benchmarks can be a very difficult subject to pin down. Choosing different ones can create drastically different backdrops to frame both short and long-term results. This was even true in our 2018 March Madness Bracket Challenge, with the value-weighted benchmark taking the top place. As investors,(...) ESG and Factor Investing [Alpha Architect]A growing number of investors are seeking to construct portfolios that simultaneously capture the 1) long-term factor premia ( value, momentum, size etc.) and 2) have attractive ESG profiles.
