According to the Wall Street Journal, which cited sources familiar with the matter, the filing of the charges would be the culmination of a three year investigation by the Federal Bureau of Investigation, the Securities and Exchange Commission and the US Attorneyâs office.
One of the main focuses of the probe has been on whether networks of expert consultants passed on non-public information between each other to inform trades.
Preet Bharara, Manhattan US Attorney, is believed to be one of the main leaders of the investigation, which alleges that inside information was used to make millions of dollars from trades.
During a speech in October, Mr Bharara, who was quoted by the Wall Street Journal, described insider trading as a âtop criminal priorityâ and added: âIllegal insider trading is rampant and may even be on the riseâ.
Bankers at Goldman Sachs are also thought to be under investigation as part of the probe, the news provider claimed.
Regulators are assessing whether executives from the investment bank leaked non-public information surrounding various transactions.
