20.01.2020. Traditionally, the Statistics of Financial Market I exam takes place during a conclusive educational trip to Frankfurt. Besides the academic program, the students have the possibility to observe how quantitative research and trading departments work in large well-known financial institutions.

 

This year, two visits were planned: one in the European Central Bank (ECB) and the other in Deutsche Bank AG (DB).

 

In the ECB main building, the Statistics Department hosted the participants for two tailored lectures on the crypto-asset phenomenon, its risks and measurement issues. The visit was particularly fruitful as one of the speakers, Urszula Kochanska, will be part of the Blockchain Research Center Workshop 2020 organised by the IRTG 1792 in April.

 

In DB, Christian Schön welcomed the visitors in the Fixed Income trading floor, introducing them to the daily routine of the bank. During the afternoon, Dr. Marius Ascheberg showed the applicability of quantitative skillsets, while Nico Weinert gave an introduction to the Electronic FX trading. To complete the guided tour, Dr. Nicolas David illustrated the mathematical foundation of exotic interest rates derivatives.

 

We thank Prof. Dr. Wolfgang K. Härdle and the PhD candidate Junjie Hu for having offered this nice opportunity to the students and we are looking forward to the start of Statistics of Financial Market II.

They received the Marie-Skłodowska-Curie Individual Fellowship with a amount of 174 806.40 EUR. The type of action is Standard European Fellowship.

 

The project title is "Quantitative Financial Risk Network Analysis with Sentiment and Herd Behaviour Measures", which is expected to be of 24 months starting within 12 months after the signature of Grant Agreement.

 

Dr. Rui REN will conduct joint research with Prof. Dr. Weining WANG on tail event driven sentiment network, quantifying investor sentiment, calibrating the option pricing model and detecting herd behaviour in the financial market. It potentially contributes to inclusive, innovative and reflective societies by supporting financial decision-making processes and managing risks for investors and institutions.

Publication

 

20.02.2020. Larisa Adamyan, Kirill Efimov, Cathy Y. Chen and Prof. Wolfgang Härdle's paper entitled "Adaptive weights clustering of research papers" has been accepted for publication in Digital Finance.

 

The abstract of the paper is as follows:

The JEL classification system is a standard way of assigning key topics to economic articles to make them more easily retrievable in the bulk of nowadays massive literature. Usually the JEL (Journal of Economic Literature) is picked by the author(s) bearing the risk of suboptimal assignment. Using the database of the Collaborative Research Center from Humboldt-Universität zu Berlin we employ a new adaptive clustering technique to identify interpretable JEL (sub)clusters. The proposed Adaptive Weights Clustering (AWC) is available on http://www.quantlet.de/ and is based on the idea of locally weighting each point (document, abstract) in terms of cluster membership. Comparison with 𝑘-means or CLUTO reveals excellent performance of AWC.

11.03.2020. Wolfgang Karl Härdle, speaker of the IRTG 1792, gave a talk on "SONIC: Social Network with Influencers and Communities" at the Charles University, Prague.

 

 

The abstract of his talk is given below:

 

Abstract

The integration of social media characteristics into an econometric framework requires modeling a high dimensional dynamic network with dimensions of parameter Θ typically much larger than the number of observations. To cope with this problem, we introduce a new structural mode SONIC which assumes that (1) a few influencers drive the network dynamics; (2) the community structure of the network is characterized as the homogeneity of response to the specific infuencer, implying their underlying similarity. An estimation procedure is proposed based on a greedy algorithm and LASSO regularization. Through theoretical study and simulations, we show that the matrix parameter can be estimated even when the observed time interval is smaller than the size of the network . Using a novel dataset retrieved from a leading social media platform StockTwits and quantifying their opinions via StockTwits and quantifying their opinions via natural natural language processing, we model the opinions network language processing, we model the opinions network dynamics among a select group of users and further among a select group of users and further detect the latent communities. With a sparsity With a sparsity regularization, we can identify important nodes in the regularization, we can identify important nodes in the network.

Event: 18 Haindorf Seminar

 


In a long tradition of seminars, the 18. Haindorf seminar, hosted by the IRTG 1792, took place from January 22 until January 26, 2019. In the former Franciscan Monastery in the village of Hejnice (Haindorf) our researchers and guests convened to share and discuss their ongoing research and present their research findings. 

 

Besides the insightful sessions there was enough time for social activity. Participants used the offers of the region such as skiing, hiking and joyful gatherings in the evenings to get to know each other and create a very collegial and friendly atmosphere. The former monastery provided not only adequate rooms for the sessions, the guests and evening activities but also czech food and a guided tour to the associated church and its crypts.

 

We want to express our sincere thanks to CiS systems s.r.o. for showing us one of their production locations in the Czech Republic.

 

We look back at a successful Haindorf seminar and look forward to come back to this beautiful place next year again.


There is more information about the participants as well as the talks on the seminar’s website.

First, it intends to generate awareness and facilitate a better understanding of the actors, phenomena and dynamics of the new financial order. Second, it explores the political and legal implications of financial and technological innovation based on blockchain technology."
