After an involuntary 24 hour blogging hiatus, and after a fast skim, not much calling out to me in Barron’s or WSJ, I felt the NEED to post something.
So let me throw a bone to the Prediction market crowd.
Here’s the trading activity in the Karl Rove Indicted by December 31 2005 futures; Anyone want to hazard a guess as to what’s up wit dat?

Note the activity on Wednesday, December 14 — towards the right hand sidfe of the chart — that’s an enormous spike in trading — its comparable to the trading when Libby was indicted.
Let me hasten to add that the Rove to be indicted on or before March 06 started trading the next day; Perhaps that had some impact on the this futures series.

Hello Barry Ritholtz,
My hypothesis is that the trading activity at InTrade/TradeSports is a follow-up of the online publication of a Time reporter’s confession about the fact that she had talks with lawyer Bob Luskin about Karl Rove.

No explanations are really convincing to me. 1) Why such a lag following an article from the 12th? The market was just asleep, then cascaded? 2) The introduction of the new contract suggests some sort of “roll” trade, but that doesn’t make any sense. 3) As I watched this happen on the 14th, I asked myself “if this is a real leak, why is it snapping back so fast?”.. which suggests 4) manipulation.. but that makes little sense either. A reflexive speculative attack makes absolutely no sense, and if someone was long and trying to spook the market into giving them better exits, that was just crazy. Speaking of manipulation and reflexivity, I will be posting on these topics over at my blog in the next day or so.
Oh, and check-out this great passage from the new Rhode/Strumpf paper “Manipulating Political Stock Markets”:
“Already” indeed!
Jason Ruspini asked why the lag.
It’s not the first time I notice such a lag.
Well, full and instant dissemination of info is the stuff of academic models, but it still seems that this market should have reacted more quickly if the articles were the cause. Nothing on the Tradesports forums on this either.
