Time spent down the bookies and the pub today could be passed off as company research as betting shop operator William Hill and pubs group JD Wetherspoon are set to issue trading statements tomorrow.Both may have cause to gripe about the weather in December, with William Hill counting the cost of lost sporting fixtures and JD Wetherspoon bemoaning the lack of passing trade.Peel Hunt thinks that if William Hill's retail business has suffered a winter chill, some of the slack might have been taken up by its online business. "Although William Hill management has made conflicting comments in the past on the impact of the weather on online, we believe that sustained poor weather does boost online revenues - this was certainly the experience of mobile gaming specialist Probability when it updated the market [last] week," the broker said.According to industry data, there were 56 race meetings abandoned out of 113 scheduled for December 2010 due to adverse weather conditions, against a comparative of 19 of 103 abandoned in December 2009, notes Panmure Gordon.It, too, is expecting the online business to compensate for loss of business in the shops from cancelled race meetings. JD Wetherspoon parted company back in October with its finance director and chief operating officer, suggesting that there may have been a disagreement over strategy, with the general view being that one faction wanted to restore margins while the other was in favour of keeping top line momentum.Wednesday's trading update will cover the group's second quarter, and Panmure Gordon thinks that like for like sales will be, at best, flat. "The group opened five new pubs (and closed two) during the first quarter, and the performance of recently opened pubs remains encouraging," the broker notes.
