(Sharecast News) - London's FTSE 250 was 0.26% higher at 20,239.98 in afternoon trade on Thursday, as WH Smith led the index upward.
The retail chain surged as it announced the acquisition of US travel retailer Marshall Retail Group for $400m and posted a 7% jump in full-year headline pre-tax profit.

Domino's Pizza was in the green after it said that it will be exiting international markets following a "disappointing" third quarter.

AJ Bell analyst Russ Mould said: "There is now a real opportunity to fix Domino's which has lost its way in recent years thanks to over-expansion, deteriorating relationships with franchisees, international woes and heightened competition.

"For years this was a great business, generating lots of cash and finding a way to sell more pizzas each year. It is now looking for a new chief executive and a new chairman, meaning we could get some fresh thinking on strategy very soon."

Down at the other end of the index, shares of Rathbone Brothers topped the fallers after it reported third quarter growth in funds under management but warned that its investment plans will diminish operating margins.

Analysts from Shore Capital said: "During an extended multi-year period where Rathbones has grown at a slower (organic) rate than many of its listed DFM peers, we have struggled to see a positive investment case, especially as its rating has generally remained at a premium to such peers."

Building materials group Grafton tumbled as it cautioned that full-year profit would be below market expectations.

In parallel, price comparison website Moneysupermarket slumped as it reported a rise third-quarter revenue thanks to a solid performance form its home services segment, but said the money business underperformed.
