Twitter analysis provides stock predictions

04.04.2011
Economists at the Technical University of Munich (Technische Universitaet Muenchen, TUM) have developed a website that predicts individual stock trends. To this end, economists are using automatic text analysis methods to evaluate thousands of daily Twitter microblog messages, so-called "tweets". On www.TweetTrader.net, current forecasts are available for all S&P 500 listed stocks.

The share price of a stock reflects investor and analyst opinions about its prospects and indicates whether positive or negative developments are on the horizon. The micoblogging platform Twitter has become an important medium for the exchange of such viewpoints. Thousands of stock-related messages are broadcasted every day via Twitter. Twittering investors mark tweets according to company stock symbols, for example, "$AAPL" for the U.S. computer company Apple.

In a study, TUM economists showed that the sentiment from Twitter messages develops similar to the stock market and even leads by a day. The Munich-based economists analyzed 250,000 Twitter messages written in a six-month period and related to S&P 500 listed companies. The result: If an investor had oriented his share purchases according to the Twitter sentiment in the first half of 2010, he would have achieved an average rate of return of up to 15 percent.

The TUM economist Timm Sprenger explains, "If a Twitter user often gives good stock recommendations, he will, as a rule, have more followers and will be 'retweeted' (i.e., quoted) more often by other users. Hereby, tweets with good recommendations are affirmed and receive greater weight in the overall analysis."

The study was the basis for the development of the website TweetTrader.net where the real-time sentiment for individual stocks can be accessed.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
