Spread betting is the form of gambling for those with deep pockets that are ready to take big risks and are attracted by the idea that the more you are right the more you win.
Unfortunately the converse is the case. The more you are wrong the more you lose so developments like the latest post-manifesto polling are being keenly watched by spread betting punters.
For most of the campaign the Conservative spreads have been hovering around the 400 Mark suggesting a massive majority of 170 or more.
That’s now moved a notch backwards following the publication overnight of the Survation and YouGov polling. The latter survey was carried out on Thursday and Friday so only partially reflected the post manifesto reaction.
My guess is that the downward trend could continue if other polls indicate the same trend. If not then we could see a reversal.
