“The crime of insider trading,” Judge Jed Rakoff has said, “is a straightforward concept that some courts have managed to complicate.” In the last eight years or so, insider trading law has wobbled visibly (in the Second Circuit in particular) in applying the standard for tipper-tippee liability originally set in the Supreme Court’s Dirks decision in 1983: from Obus (2012) to Newman (2014), with a detour to the Supreme Court in Salman (2016), and then two Martoma opinions (2017 and 2018).
