[{"title":"I’ll Have What S/he’s Having: A Case Study of a Social Trading Network","user_id":"67265","abstract":[{"text":"Opinion leaders of an investment network can have a significant impact on capital mar-kets because their investment decisions are adopted by their peers and trigger large trad-ing cascades, increasing herding behavior and comovement among stock returns. This paper analyzes the interaction-based relations of traders from a large social trading plat-form and identifies the driving forces and the opinion leaders within a large online trading network as the nodes with the highest centrality and the highest force of infection, respec-tively. Relying on recent insights from epidemiological research, I maintain that central-ity identifies the most central traders in the network, while the expected force quantifies the most influential traders and their spreading power. I study the behavior and charac-teristics that set central and influential traders apart from other traders. The ability to identify focal points and their trading behavior within a trading network is important for investors, investment advisers, and policy makers.","lang":"eng"}],"article_type":"original","publication_status":"published","date_created":"2018-03-20T11:34:47Z","status":"public","department":[{"_id":"186"},{"_id":"578"}],"keyword":["Online trading","investment advice","network modeling","Expected Force","herding."],"publication":"Proceedings of the International Conference on Information Systems","author":[{"id":"67265","last_name":"Pelster","orcid":" https://orcid.org/0000-0001-5740-2420","full_name":"Pelster, Matthias","first_name":"Matthias"}],"urn":"14524","date_updated":"2022-01-06T06:52:00Z","_id":"1452","citation":{"mla":"Pelster, Matthias. “I’ll Have What S/He’s Having: A Case Study of a Social Trading Network.” Proceedings of the International Conference on Information Systems, 2017.","bibtex":"@article{Pelster_2017, title={I’ll Have What S/he’s Having: A Case Study of a Social Trading Network}, journal={Proceedings of the International Conference on Information Systems}, author={Pelster, Matthias}, year={2017} }","ama":"Pelster M.
