Artificial intelligence is increasingly being used in finance, from investment management to financial analysis. However, recent research suggests that highly accurate market predictions do not necessarily result in better investment outcomes. In two complementary studies from Pusan National University, researchers investigated how financial AI can be improved to make better decisions and how the performance of these systems can be evaluated using a proposed framework. The findings support the development of reliable financial AI.
Economists from HSE University, together with colleagues from international universities, have analysed stock market movements over almost a century and proposed an investment strategy that could have delivered returns nearly twice as high as the market average. Their research suggests following a momentum strategy during periods of sustained market growth and switching to a value strategy after prolonged market declines. The study has been published in the Journal of Banking and Finance.
A few years ago, the first ceramic finds came to light during construction work in the Burg district of the municipality of Hannersdorf. Geomagnetic surveys in subsequent years provided evidence of numerous kilns that are thought to lie hidden beneath the field. In a recent educational excavation led by Basema Hamarneh from the University of Vienna, archaeologists have now uncovered two pottery kilns. A further 100 kilns are thought to still lie buried – an unprecedented discovery of a local production centre for utilitarian pottery from the Roman period. The finds date from the mid-1st century to the mid-2nd century CE.
For years, social media companies have faced pressure from users and government watchdogs to stop misinformation from distorting elections, deepening political divisions and undermining Americans’ trust in institutions. But what if dramatically reducing people’s exposure to unreliable sources that frequently spread misinformation doesn’t actually change what they believe? In new research, UC Berkeley political scientist Olivier Bergeron-Boutin and co-authors find that even when people are exposed to less social media misinformation, their political beliefs don't change much.
