It is a good book, but it isn't completely candid about one part of the FT's investigation.
When Dan McCrum was under threat of arrest in Germany, that was because Paul Murphy, Dan's editor, did in fact give away to some of his contacts the fact that they were coming out with a negative story on Wirecard and the time it would be published. Murphy has form for trading his own scoops with stock traders for favours. The Wirecard recording of one of Murphy's mates talking about shorting Wirecard to take advantage of the story is accurate and had Murphy (but I very much doubt McCrum) bang to rights.
McCrum's explanation for this is that Murphy's associates knew the exact time of the story being released because they had happened to guess it by sheer luck. Clearly if that's what Murphy told him he should have been a little more skeptical.
Ultimately the FT's internal investigation into Paul Murphy's behaviour and BaFin's into McCrum's work were abandoned for the same reason: the Wirecard revelations were legit, and much more serious than Murphy's breaches of journalistic ethics.
But if the trade came up as a matter of an investigator researching a company, and communicating with people about the details. Even if they disclosed the exact time they planned on publishing this information, is it insider trading?
Wouldn't you have to been privy to information from inside the company itself? Otherwise anybody could have investigated this person, and had equal opportunity to discover negative things to expose?
Given FT had no financial interest in wirecard I’m not sure it’s insider trading? Breach of the code of conduct of FT and basic journalistic ethics of course, but using investigators to find out bad things about companies and using that information to trade is pretty normal and not insider trading
It’s not insider trading as there is no material non-public information involved. Were the information false, it would likely be actionable market manipulation. But because the information was true, from the perspective of the authorities nothing wrong here.
On the other hand, there may be ethical (but not legal) issues from the perspective of the publisher.
McCrum had already pointed out that Marsalek was at least looking for connections intelligence services, had confirmed connections to at least some former intelligence operatives, and that there were a lot of pieces of evidence that pointed to the strong possibility of connection to Russia. He just didn't find definitive proof, but that was also not the primary focus of his book.
Yes the book mentions towards the end that Marsalek's location was unknown, but possibly in Russia or Belarus where Interpol would not be able to do much.
I recall it was hinted at in the last episode only. the langue in the documentary seemed more like "alleged" ... it is very different from what is published in this report. shopping for a mercenary army in Libya = Not just a different ball-game, but an entirely different sport.
