Published / Preprint: A study of co-movements between USA and Latin American stock markets: a cross-bicorrelations perspective. (arXiv:1503.06926v1 [q-fin.ST])

Posted: 24 Mar 2015 05:36 PM PDT

In this paper we use the Brooks and Hinich cross-bicorrelation test in order to uncover nonlinear dependence periods between USA Standard and Poor 500 (SP500), used as benchmark, and six Latin American stock markets indexes: Mexico (BMV), Brazil (BOVESPA), Chile (IPSA), Colombia (COLCAP), Peru (IGBVL) and Argentina (MERVAL). We have found windows of nonlinear dependence and co-movement between...

Published / Preprint: Optimal Position Management for a Market Maker with Stochastic Price Impacts. (arXiv:1503.07007v1 [q-fin.PR])

Posted: 24 Mar 2015 05:36 PM PDT

This paper provides the optimal position management strategy for a market maker who has to face uncertain customer orders in an "illiquid" market, where the market maker's continuous trading through a traditional exchange incurs stochastic linear price impacts. In addition, it is supposed that the market participants can partially infer the position size held by the market maker and their...

Blog Post: TheFinancialServicesClub: Does anyone really need a mobile wallet?

Posted: 24 Mar 2015 05:56 AM PDT

Reflecting on another conversation at last week’s conference, there were lots of discussions about why the mobile wallet wars were lost.  No one’s won the mobile wallet war yet, not even Apple, but it is there to be won.  In fact I wondered why it took a firm like Apple to take up the mantra and aim for this crown â€" not forgetting WeChat, Alipay and others â€" and realised...

Posted: 23 Mar 2015 05:36 PM PDT

The recent economic crisis has raised a wide awareness that the financial system should be considered as a complex network with financial institutions and financial dependencies respectively as nodes and links between these nodes. Systemic risk is defined as the risk of default of a large portion of financial exposures among institution in the network. Indeed, the structure of this network is an...

Posted: 23 Mar 2015 05:36 PM PDT

Crashes have fascinated and baffled many canny observers of financial markets. In the strict orthodoxy of the efficient market theory, crashes must be due to sudden changes of the fundamental valuation of assets. However, detailed empirical studies suggest that large price jumps cannot be explained by news and are the result of endogenous feedback loops. Although plausible, a clear-cut empirical...

Published / Preprint: Insights in Economical Complexity in Spain: the hidden boost of migrants in international tradings. (arXiv:1503.06020v1 [physics.soc-ph])

Posted: 22 Mar 2015 05:36 PM PDT

We consider extensive data on Spanish international trades and population composition and, through statistical-mechanics and graph-theory driven analysis, we unveil that the social network made of native and foreign-born individuals plays a role in the evolution and in the diversification of trades. Indeed, migrants naturally provide key information on policies and needs in their native...

Posted: 22 Mar 2015 05:36 PM PDT

A classification of companies into sectors of the economy is important for macroeconomic analysis and for investments into the sector-specific financial indices and exchange traded funds (ETFs). Major industrial classification systems and financial indices have historically been based on expert opinion and developed manually. Here we show how unsupervised machine learning can provide a more...
