Labour to win NP and Little to win NP seperate stocks?

Sorry if this has already been discussed.

Why are there different stock options for Andrew Little to win NP and Labour to win NP?

Is this because Little is not confirmed as candidate yet or is the Labour option for Labour to get a bigger share of the vote?

Cheers, Docco

I think the Little stock was launched well before the other NP electorate stocks and thus was also capturing the likelihood of him standing in NP. I'm pretty sure he's been confirmed as the Labour candidate and, if that's the case, the two stocks should be priced identically (apart from the low probability event of him not ending up standing due to scandal, death, etc).

Thanks Economist. That makes sense.
