<div style="text-align: justify;">The TUM School of Management has awarded one of the first phd titles worldwide for research on Twitter. Timm Sprenger's dissertation on "<a href="http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:bvb:91-diss-20110729-1079371-1-2">The Information Content of Microblogs and their Use as an Indicator of Real-World Events</a>" investigates whether information extracted from Twitter can serve as an indicator of real-world events and explores the mechanism that explains the efficient aggregation of information. </div><div style="text-align: justify;">The results illustrate that the sentiment (i.e., bullishness) of stock-related tweets is correlated with abnormal stock returns. In addition, they provide empirical evidence supporting the idea that followership relationships and retweets represent the Twittersphere's "currency" for weighing information, since users providing above average investment advice are retweeted (i.e., quoted) more often and have more followers. Thus, this dissertation contributes to the understanding and use of social media content in social science research.</div><br />

The associated demo paper is available online as part of the <a href="http://www.aaai.org/ocs/index.php/ICWSM/ICWSM11/paper/view/2894">conference proceedings</a>. On this occasion, we also met with a "Who is Who" of the Twitter research community including <a href="http://informatics.indiana.edu/jbollen/Home.html">Johan Bollen</a> from Indiana University (author of "<a href="http://arxiv.org/PS_cache/arxiv/pdf/1010/1010.3003v1.pdf">Twitter mood predicts the stock market</a>").

We have explored the relationship of S&P 500 stocks in terms of joint mentions in stock microblogs (for example, the tweet “<i>Big banks up or down with Bernanke's re-nomination? $C $BAC</i>" jointly mentions Citigroup and Bank of America and thus associates these companies with each other). The figure below shows the relationship of S&P 500 stocks in terms of joint mentions in 439,960 English-language, stock-related microblogging messages. For a rough comparison with the classic SIC industry classification, the shape and color of each stock symbol represents the one-digit SIC industry group. We can interpret proximity of a group of stocks roughly as the degree to which they are related. </div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">We find that many subgroups of stocks are consistent with our intuition of classic industry delineations. Financial firms, such as Goldman Sachs (GS), JP Morgen (JPM), and Bank of America (BAC) are closely interconnected. There are also tight-knit smaller groups of stocks, such as the media companies Disney (DIS), CBS Broadcasting (CBS) and Time Warner (TWX). In addition, some subgroups exist that are not connected to the rest of the network, for example the insurance companies WellPoint (WLP) and United Health (UNH), the logistics firms United Parcel Service (UPS) and Fedex (FDX), and the hardware stores Home Depot (HD) and Lowe’s (LOW). Their isolated position suggests that these companies form micro industries that are often subject to the same news items, but not frequently associated with other firms.</div><div style="text-align: justify;">The network graph not only confirms classical industry groupings, but also reveals interesting connections between these industries. For example, while Exxon Mobile (XOM) is obviously closely related to other major energy firms such as Chevron (CVX) and ConocoPhillips (COP), it is also linked to subcontractors such as the exploration firms Anadarko Petroleum (APC) and Halliburton (HAL), which in turn are associated with their equipment suppliers Schlumberger (SLB) and Cameron (CAM). Note that these relationships cut across traditional SIC categories. Online retailer Amazon (AMZN) is another interesting example in this respect, because the company appears to be a hub that is associated with traditional “brick and mortar” retailers, such as Walmart (WMT), Target (TGT) and Costco (COST), online retailers, such as Priceline (PCLN) and Ebay (EBAY), computer soft- and hardware firms, such as Apple (AAPL), Microsoft (MSFT) and Intel (INTC), and communication providers, such as AT&T (T). The network also highlights particularly competitive relationships, such as those between Coke (KO) and Pepsi (PEP) or Visa (V) and Mastercard (MA), as well as issues related to corporate control and ownership, such as the strong link between Disney (DIS) and its parent company General Electric (GE).</div><div style="text-align: justify;">We conclude, that joint mentions of stocks on Twitter offers unique and rich insights into the relationship between companies.</div><div class="separator" style="clear: both; text-align: justify;"><br />

As a result, the stock has plummeted. The case is a good example of how TweetTrader.net instantly reflects market developments, often even before it hits major news wires. As you can see, <i>TweetTrader.net Sentiment</i> on $AAPL was <i>down almost 30%</i> and people were talking mostly about issues related to Corporate Governance (which, according to our <a href="http://tweettrader.blogspot.com/2011/01/what-topics-are-stock-microbloggers.html">research</a>, is largely CEO-related) and Operations.</div><br />

We have classified thousands of tweets into the following news or event categories:<i> Corporate Governance, Financial Issues, Operations, Restructuring Issues, Legal Issues, and Technical Trading</i>. In addition, to allow for more granular analysis, we have defined <i>subcategories </i>for which we found a substantial number of messages among our data set (e.g., stock-related vs. market-related technical trading signals).</div><div style="text-align: justify;">The table below provides an overview of the event categories and sample messages assigned to the respective class. It shows that technical trading signals are the most frequently mentioned event category with references in almost one third of all messages (34.0%), among which stock-related signals make up the vast majority (28.2%). Next are comments regarding company operations (20.3%), especially product development (9.4%), operational performance (4.2%) and marketing (4.2%). Financial issues come third as an event category (13.3%) with a majority of messages dedicated to the discussion of earnings results (6.9%). Restructuring issues (6.1%), Legal Issues (3.5%) and topics related to Corporate Governance (3.3%) are mentioned less frequently. The distribution of topics shows some interesting differences to professionally edited newspapers and confirms that stock microblogs provide information "off the beaten track".</div><div style="text-align: justify;"><br />

We define the quality of a tweet as the accuracy of this recommendation relative to same-day returns of the stock in question (i.e., the tweet "$AAPL going up" gets a point if AAPL was up by the end of the day). The quality of a particular user is the average quality of all tweets posted by this individual. We find that even among users with hundreds of messages, we can identify some that seem to consistently provide higher quality investment advice than others. And the winner is...</div><br />

We manually classified 2,500 tweets as either buy, hold, or sell signals. Roughly half of these messages were considered to be hold/neutral signals (49.6%). Among the remainder, buy signals were more than twice as likely (35.2%) as sell signals (15.2%). This indicates that stock microblogs appear to be more balanced in terms of bullishness than internet message boards where the ratio of buy vs. sell signals ranges from 7:1 (Dewally, 2003) to 5:1 (Antweiler & Frank, 2004).</div><br />
<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhaNFw1TAb7PDgMIcTFRJnOuR4ezNkk0LBfmsGG8nm8HR_NSEiVi6GgcvVFrb-GL7BxbjlCTL37bN4AuLFeY-AlHUth8GrL8Nhl0VofEvV6M_yJBnmEXRtFLbqgqlpjU7z31WGkHkVzR7HK/s1600/BuySell_pie+chart.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="292" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhaNFw1TAb7PDgMIcTFRJnOuR4ezNkk0LBfmsGG8nm8HR_NSEiVi6GgcvVFrb-GL7BxbjlCTL37bN4AuLFeY-AlHUth8GrL8Nhl0VofEvV6M_yJBnmEXRtFLbqgqlpjU7z31WGkHkVzR7HK/s320/BuySell_pie+chart.JPG" width="320" /></a></div><br />
The table below shows a few typical examples. Our analysis of the most common words per class draws a semantic profile of buy, hold and sell signals. Obviously, some features occur frequently in all classes (e.g., numbers and hyperlinks). However, beyond these universal features, the most common words reasonably reflect the linguistic bullishness of the three classes. Positive emotions, for example, are much more likely among buy signals. In addition, buy signals often contain bullish words with an origin in technical analysis (e.g., “moving average”, “resistance”, “up”, or “high”), operations (e.g., “acquire”), financials (e.g., “beat”, “earn”), or trading (e.g., “buy”, “long”, “call”). Sell signals contain many corresponding bearish words in the areas of technical analysis (e.g., “support” and “cross”), financials (e.g., “loss”) or trading (e.g., “short” and “put”). As a results of the frequent occurrence of negative adjectives (e.g., “weak”, “low”) and verbs (e.g., “decline”, “fall”), negative emotions are among the most common features in sell signals. Positive and negative emotions are much more equally balanced in hold messages, which also contain more neutral words such as product names (e.g., “ipad”, “iphone”) and make fewer references to specific price targets (i.e., dollar values).<br />

In the first 6 months of this year, we have collected a large number of stock-related microblogging messages containing the dollar-tagged ticker symbol of an S&P 100 company. The figure shows the distribution of messages throughout the day. We observe a significant spike in message volume before the markets open. The majority of tweets are posted during the trading hours between 9:30 am and 4:00 pm. This provides further evidence that stock microblogs are truly used by financial professionals to exchange relevant trading ideas in real time and when it matters. They truly capture the market conversation.</span></div><br />

The site is no longer used only for personal status updates, but represents the fastest way to distribute new and valuable information. In the context of the social semantic web, there are numerous attempts to aggregate this information in a meaningful fashion.<br />
<br />
Last year, a group at the <a href="http://portal.mytum.de/welcome/">TUM School of Management</a> has launched the <a href="http://www.strategie.wi.tum.de/index.php?id=77">research project TUitter</a>. As part of this project, we investigate in how far the information content on Twitter can be used as an indicator of events in the offline world. In the context of the German federal elections, we have already shown that the information content of Twitter messages can serve to predict election results and reflect the political landscape surprisingly well (for details, <a href="http://www.strategie.wi.tum.de/fileadmin/tuwib17/www/ICWSM10_Predicting_Elections_with_Twitter.pdf">read the paper</a> or <a href="http://videolectures.net/icwsm2010_sprenger_pet/">watch the presentation at the International Conference on Weblogs and Social Media</a>, which took place in Washington in May). Initial results to use Twitter as an indicator of financial market activity are equally promising. As part of this analysis we are using machine learning techniques to classify message board content automatically and extract the sentiment contained in the postings.</div><div style="text-align: justify;"></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">Currently we are transferring these research results into an online application that harnesses this "wisdom of crowds" and may help aggregate stock-related financial information. It provides the online community with an innovative approach to generate fresh trading ideas and investment advice.</div>TweetTraderhttp://www.blogger.com/profile/08160380597432676005noreply@blogger.com0
