This is the result of a joint study in which search engine query data are analyzed by Tobias Preis and Daniel Reith (Johannes Gutenberg University Mainz, Germany), together with H. Eugene Stanley (Boston University, USA). "We asked the question whether or not there is a link between search volume data and financial market fluctuations on a weekly time scale", says Preis.
Search engine query data can deliver insight into the behavior of individuals who are submitting several hundred million search engine queries around the day each day. Aggregated query data provided by Google cover the time period from 2004 to present and are available for scientific use.
"Both collective 'swarm intelligence' of internet users and financial market participants can be regarded as a complex system of many interacting subunits that react quickly to external changes", explains Preis.
The authors find clear evidence that weekly transaction volumes of S&P 500 companies are correlated with weekly search volumes of corresponding company names. Thus, increasing transaction volumes coincide with an increasing number of search queries for the corresponding company name. However, stock price variations and changes of company's search volume show no significant correlation. The authors verify this effect for individual stocks as well as for the S&P 500 on an aggregated level. "Thus, search volume data seems to coincide with the attractiveness of trading a stock", says Reith. The authors highlight that their finding can be of crucial importance for a deeper understanding of financial markets' complexity.
The study is published in the latest issue of Philosophical Transactions of the Royal Society A.Reference:

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
