Twitter investment strategy?
The industry has been talking about using twitter to find investment ideas for years. Back in 2012, a twitter-based hedge fund lasted about a month and produced returns of about 2% (which doesn't sound good, but the returns for the overall market were actually negative for that same month)....so the twitter HF did outperform the market (in a very short sampling).
But no one has been able to figure out the secret to bring in social data to run an investment strategy for the long haul. It will happen eventually, but as Gonzalez says, there has to be a way to verify the 'news' on Twitter to make sure it is legitimate.
