L'effetto di Twitter sulle azioni.

[Autom. eng. transl.] When in August 2011 the Societé Générale title was suspended due to a "tweet" that reported the possible difficulties for the bank, it immediately became clear that the financial information had completed a new and irreversible step. The origin of the news that caused the sudden decline of 14% of the French giant is to be found in an article of an English tabloid - the "Mail on Sunday" - then taken up again on twitter by the account of the most authoritative Telegraph and from there it bounced back to all operating rooms in the world. If there had been need for proof of the potential influence of twitter and social media in general on the financial markets, one could not have devised a more evident one.
