Motivation and Theoretical Background  Increasing use of the internet (smart phones, tablets and computers)  Internet has become the main source for information gathering process  Buy-/Sell-Decision is influenced by diverse factors (e.g. economic and political news) Price of a stock is determined by demand and supply Information gathering process lies between an event and a financial transaction Motivation and Research Question

6 6 Textmasterformate durch Klicken bearbeiten Google Data Data Search Volume Indices (SVI) derived from Google Trends (http://www.google.com/trends/)http://www.google.com/trends/ Normalized values, scaled measured between 0 and 100 The weekly data covers search queries conducted from Sunday to Saturday. Google Trends makes the newest weekly data available with an approximate two day delay.

10 10 Textmasterformate durch Klicken bearbeiten Definition of Search Volume (SV) Change Research Design and Methodology where:t = week of observation, SV = Search Volume Da, Z., Engelberg, J. and Gao, P. (2011) Finding: Search queries conducted two weeks prior, have a predictive ability for the capital market Drake et al. (2012) Finding: Information demand through the internet starts increasing, on average, about two weeks prior to earnings announcements

11 11 Textmasterformate durch Klicken bearbeiten Positive vs. Negative Correlation Research Design and Methodology Positively correlated (from 2006 – 2008) see Da et al. (2011) and Barber and Odean (2007) Upward trend:buy signal (long position) Downward trend:sell signal (short position) Negatively correlated (from 2006 – 2008) see Preis et al. (2013) and Simon (1955) Downward trend:buy signal (long position) Upward trend:sell signal (short position)

16 16 Textmasterformate durch Klicken bearbeiten Main Findings Findings and Conclusion  85 GTIS outperform the market (buy-and-hold)  Best GTIS “properties+property” achieves a performance of 2,181.6 % (47.9 % p.a.)  26 GTIS have a lower risk exposure than the buy-and-hold strategy despite higher returns  GTIS with the highest hit rates are not automatically the best performers  The Top 12 search terms are strictly real estate related (overall)  Strong performance of real estate GTIS during the crisis (09/15/2008 - 02/21/2011)  Significant positive correlation between search relevance and investment performance (Kendall’s τ = 0.417, z-stat = 4.274; Spearman’s ρ = 0.580, t-stat = 4.929)  Investment strategies based on Google search data are able to outperform the market particularly during volatile market phases

20 20 Textmasterformate durch Klicken bearbeiten The role of real estate Analysis and Findings  Why do real estate related searches have a better sense of prediction?  Graff (2001, p. 104): “[…] the investment value of an asset equals the present value of future net cash flows expected from the asset”. Investors gather information about potential future cash flows Reviewing the property market as a whole REIT income is bound to be highly correlated to the property markets  REIT investors gather information about the underlying assets of their stocks  Property-specific GTIS exploit this revealed set of information  Real estate related terms, that are less specific and capture interest on a larger scale, i.e. are more general, perform more successfully.

23 23 Textmasterformate durch Klicken bearbeiten Conclusions  This field of research only stands at the beginning in its approach to predict financial markets  Buy-/Sell-Decision is most probably influenced by diverse factors (e.g. economic and political news), but: price of a stock is still determined by demand and supply in between the happening of an event and a financial transaction conducted by a person lays a process of information gathering.  Ever-increasing use of the internet (smart phones, tablets and laptops) is improving the predictive power  Internet has become the main source for the information gathering process Gauging this process could be of high relevance for the prediction of people’s decisions and the movement of the market. Whilst the analysis proposed is focused on the real estate market (REITs), we believe that this approach can also be applied to other tradable asset classes.
