Selling Ron Paul short 4
The New Hampshire primary is over, and the Ron Paul contract at Intrade is in free fall. Before Iowa, Ron Paul traded as high as 9, meaning that he had a 9% chance of getting the Republican nomination. After Iowa but before New Hampshire, he traded at around 5. Now he’s at 2.5.
I still say he should be trading at zero, but here we have to face a structural bias at Intrade. Intrade requires traders to put up capital equal to their maximum possible loss. Unfortunately, Intrade does not pay interest on small accounts, so there is an opportunity cost to every trade.
The Ron Paul contract runs until August 31st, about 8 months from now. At 2.5, someone on the long side puts up $2.50, which is the most he can lose if the contract goes to zero. The person on the short side, me for example, has to put up $97.50, which is the most I can lose if the contract goes to 100 (Ron Paul gets the nomination). The most I can make is $2.50, which is less than I could make by putting the $97.50 in a money market account for 8 months. When I shorted Ron Paul at 7.7, it was an attractive trade. At 2.5, not so much. Time to take the money and run.
Alternatively, I can wait for Super Tuesday and maybe cover at 1.5 instead of 2.5. I have no problem with waiting a month to pick up another point, but my whole thesis is that the Paulistas are behaving irrationally. Do I really want to bet that Super Tuesday will make them less irrational?
