Pairs Trading - Part 2: Practical Considerations [Jonathan Kinlay]
One of the first things you quickly come to understand in equity pairs trading is how important it is to spread your risk. The reason is obvious: stocks are subject to a multitude of risk factors – amongst them earning shocks and corporate actions -that can blow up an otherwise profitable pairs

Cointegration Breakdown [Jonathan Kinlay]
One of the perennial difficulties in developing statistical arbitrage strategies is the lack of reliable methods of estimating a stationary portfolio comprising two or more securities. In a prior post (below) I discussed at some length one of the primary reasons for this, i.e. the lower power of

Beating the S&P500 Index with a Low Convexity Portfolio [Jonathan Kinlay]
A primer on beta convexity and its applications is given in the following post: The essential idea is to evaluate the beta of stock during down-markets, separately from periods when the market is performing well. Beta convexity is a measure of how stable a stock beta is across market regimes, and by

Can Machine Learning Be Used To Predict Market Direction? The 1,000,000 Model Test [Jonathan Kinlay]
During the 1990’s the advent of Neural Networks unleashed a torrent of research on their applications in financial markets, accompanied by some rather extravagant claims about their predicative abilities. Sadly, much of the research proved to be sub-standard and the results illusionary, following

On Testing Direction Prediction Accuracy [Jonathan Kinlay]
As regards the question of forecasting accuracy discussed in the paper on Forecasting Volatility in the S&P 500 Index, there are two possible misunderstandings here that need to be cleared up. These arise from remarks by one commentator as follows: “An above 50% vol direction forecast looks

Robustness in Quantitative Research and Trading [Jonathan Kinlay]

The Lognormal Mixture Variance Model [Jonathan Kinlay]
The LNVM model is a mixture of lognormal models and the model density is a linear combination of the underlying densities, for instance, log-normal densities. The resulting density of this mixture is no longer log-normal and the model can thereby better fit skew and smile observed in the market. The

Understanding Stock Price Range Forecasts [Jonathan Kinlay]

Modeling Volatility and Correlation [Jonathan Kinlay]
In a previous blog post I mentioned the VVIX/VIX Ratio, which is measured as the ratio of the CBOE VVIX Index to the VIX Index. The former measures the volatility of the VIX, or the volatility of volatility. A follow-up article in ZeroHedge shortly afterwards pointed out that the VVIX/VIX ratio had
