WOW: @cbouzy: Someone started dumping Lockheed Martin stock just before Trump's tweet: Tweet was 8:26 AM EST, LMT dumping started 8:20 AM pic.twitter.com/43hyxd1s5E— Amichai Stein (@AmichaiStein1) December 12, 2016
The legalities of different kinds of insider trading are complex from a libertarian perspective.
However, when a public official's activity is involved and those around him, I have always considered it a prosecutable offense. Since Trump's tweet was concerning his view with regard to actions he might take once on the American throne, I consider this trading prosecutable.
The SEC should hunt down the culprit!
