Researchers from the University of Turku and the University of Palermo have investigated the role of high-frequency traders in the markets. https://phys.org/news/2021-06-stock-increasingly-networked-due-high-frequency.html Economics & Business Tue, 29 Jun 2021 12:22:17 EDT news544188133 New research from Northwestern University finds that balanced professional networks are more important than individual talent when it comes to high-risk decision making. https://phys.org/news/2019-06-enemy-friend.html Economics & Business Mon, 17 Jun 2019 08:32:09 EDT news479979120 In the U.S. today, the majority of professional stock market traders are young males and new evidence suggests biology strongly influences their trading behavior. According to a new study in the INFORMS journal Management Science, this could be a significant contributor to fluctuations in the market, as high testosterone levels can cause these traders to overestimate future stock values and change their trading behavior, leading to dangerous prices bubbles and subsequent crashes. https://phys.org/news/2017-10-raging-bull-link-testosterone-stock.html Economics & Business Tue, 10 Oct 2017 15:16:36 EDT news426867382 Financial traders are better at reading their 'gut feelings' than the general population – and the better they are at this ability, the more successful they are as traders, according to new research led by the University of Cambridge. https://phys.org/news/2016-09-gut-successful-financial-traders.html Economics & Business Mon, 19 Sep 2016 09:26:22 EDT news393495970 (PhysOrg.com) -- Long-standing problems are quite often solved simultaneously by various people working alone. Take, for example, naturalists Charles Darwin and Alfred Russel Wallace, who separately proposed the theory of evolution by natural selection. Or French physicist Edme Mariotte who independently landed on what is now known as Boyle's law of gases, without knowing that Robert Boyle had just done the same. Robert King Merton, the grandfather of social science, called it the concept of multiples. Most discoveries and inventions, he said, are made by multiple independent individuals unintentionally acting in sync, as opposed to by a single genius. It's not that people are intentionally cooperating, but rather, working in sync seems to increase the probability a problem will be solved. https://phys.org/news/2011-03-traders-sync-money.html Economics & Business Thu, 17 Mar 2011 06:37:29 EDT news219562628 (PhysOrg.com) -- Cambridge researchers have identified a group of traders consistently able to outperform the market, even during the credit crisis. https://phys.org/news/2009-11-biology-profit-traders.html Mathematics Wed, 25 Nov 2009 07:28:40 EST news178349551 (PhysOrg.com) -- Philips Electronics and the Dutch bank ABN AMRO have joined forces to develop a "Rationalizer" bracelet system that detects stress levels and displays a warning to help day-traders avoid making hasty decisions. https://phys.org/news/2009-11-rationalizer-bracelet-traders-theyre-stressed.html Consumer & Gadgets Tue, 17 Nov 2009 07:45:34 EST news177666286
