International Business Machines launched the IBM Watson Trend app on Wednesday, which uses tens of millions of online conversations to gain insight on consumer sentiment and shopping patterns. The app is available for free on the Apple store. Among the trends and predictions already highlighted by the app, it says three Lego sets - Star Wars, Friends and Lego City - will likely sell out for the 2015 holiday season and Thanksgiving will set a record for mobile sales and mobile traffic over the five-day holiday weekend. IBM shares are down 16.3% for the year so far. The Dow Jones Industrial Average is down 1.9% for the same period.
