Research Library: Dynamical Bias in the Coin Toss

Posted: 04 Dec 2012 02:21 AM PST

Persi Diaconis, Susan Holmes, Richard Montgomery   Abstract We analyze the natural process of flipping a coin which is caught in the hand. We prove that vigorously-flipped coins are biased to come up the same way they started. The amount of bias depends on a single parameter, the angle between the normal to the coin and the angular momentum vector. Measurements of this parameter based on...

Blog Post: Falkenblog: New Low Vol Index

Posted: 03 Dec 2012 07:31 PM PST

This one is a bit too cute for me. The CBOE LOVOL Index combines a portfolio of SP 500 stocks and simultaneously selling SPX calls and buying one-month VIX 30-delta calls on a monthly basis. The LOVOL mix of VIX and SPX options reduces the chance of shortfalls below -10% but still preserves the bulk of market gains. By construction, the LOVOL delivers returns between the BXM and VXTH, or a...

Published / Preprint: Effect of detrending on multifractal characteristics. (arXiv:1212.0354v1 [physics.data-an])

Posted: 03 Dec 2012 05:32 PM PST

Different variants of MFDFA technique are applied in order to investigate various (artificial and real-world) time series. Our analysis shows that the calculated singularity spectra are very sensitive to the order of the detrending polynomial used within the MFDFA method. The relation between the width of the multifractal spectrum (as well as the Hurst exponent) and the order of the polynomial...

Published / Preprint: A note on estimating stochastic volatility and its volatility: a new simple method. (arXiv:1212.0380v1 [q-fin.GN])

Posted: 03 Dec 2012 05:32 PM PST

We present a new simple method of estimating stochastic volatility and its volatility. This method is applicable to both cross-sectional and time-series data. Moreover, this method does not require volatility data series.

Published / Preprint: Maximum Entropy distributions of correlated variables with prespecified marginals. (arXiv:1212.0440v1 [cond-mat.stat-mech])

Posted: 03 Dec 2012 05:32 PM PST

The problem of determining the joint probability distributions for correlated random variables with pre-specified marginals is considered. When the joint distribution satisfying all the required conditions is not unique, the "most unbiased" choice corresponds to the distribution of maximum entropy. The calculation of the maximum entropy distribution requires the solution of rather complicated...

Published / Preprint: Second-order BSDEs with general reflection and Dynkin games under uncertainty. (arXiv:1212.0476v1 [math.PR])

Posted: 03 Dec 2012 05:32 PM PST

The aim of this paper is twofold. First, we extend the results of [32] concerning the existence and uniqueness of second-order reflected 2BSDEs to the case of upper obstacles. Then, under some regularity assumptions on one of the barriers, similar to the ones in [9], and when the two barriers are completely separated, we provide a complete wellposedness theory for doubly reflected second-order...

Published / Preprint: Modeling non-stationarities in high-frequency financial time series. (arXiv:1212.0479v1 [q-fin.ST])

Posted: 03 Dec 2012 05:32 PM PST

We study tick-by-tick financial returns belonging to the FTSE MIB index of the Italian Stock Exchange (Borsa Italiana). We find that non-stationarities detected in other markets in the past are still there. Moreover, scaling properties reported in the previous literature for other high-frequency financial data are approximately valid as well. Finally, we propose a simple method for describing...

Research Library: High-frequency trading behaviour and its impact on market quality: evidence from the UK equity market

Posted: 03 Dec 2012 06:36 AM PST

Evangelos Benos and Satchit Sagade   Abstract We analyse the intraday behaviour of high-frequency traders (HFTs) and its impact on aspects of market quality such as liquidity, price discovery and excess volatility.  For that, we use a unique transactions data set for four UK stocks, over the period of a randomly selected week.  Our data identifies the counterparties to each...
