NEW YORK (TheStreet) -- The social-media universe can be a powerful indicator for potential stock and market movements. A European Central Bank report released last week highlighted that bullishness on Twitter (TWTR) has a "statistically and economically significant predictive value in respect of share prices." So what was the social-media universe most abuzz about this week?
Here's our weekly round-up of most discussed stocks on Twitter and traditional media channels -- stock-related news that saw the highest levels of engagement amongst market experts and valid sources.
- Pearson (PSO): The market was buzzing when news hit earlier this week that Pearson was in talks to sell the Financial Times as the organization looks to focus on its core education unit. The FT was rumored to fetch nearly $1.6 billion in the event of a sale. News broke on July 23 that Nikkei is buying the FT for 1.29 billion, lifting Pearson's share price. Now the company is reportedly in talks to sell The Economist, another of its media properties.
- JPMorgan (JPM - Get Report): On July 21, U.S. and Israeli authorities made a series of arrests tied to the JPMorgan hack which was revealed to be related to a complex securities fraud plot. The suspects are believed to have taken part in a pump-and-dump scheme.
