Interdealer broker ICAP (IAP) topped the losers board this morning, down 6.9% at 300p, after reporting 'extremely challenging' trading conditions in the nine months to 31 December 2012. The FTSE 100 counter is a good proxy for the global banking sector its serves and that activity has tailed off in March perhaps underlines how trading activity could be damaged by global regulatory moves to curtail the speculative activities of large financial organisations.


Volatility is good for ICAP, which facilitates trading between banks who don't want to deal on exchange, and so this year's monetary loosening by the Bank of Japan, and consequent devaluation in the yen created generated good fees in January and February. Foreign exchange is by far the biggest market and the prospect of an all-out global currency war as economic growth continues to disappoint creates a favourable backcloth, but not if proprietary trading is taxed out of existence or made unfeasible by new rules to ringfence banks' retail and investment banking operations.


For a UK equity fund manger, the FTSE 100 pushing on five-year highs is manna from heaven. Hence no surprise Liontrust Asset Management's (LIO) year-end trading update was always going to be bullish, stock up 1.2% to 166p on news of £233 million of net inflows for the first quarter of 2013.


After an initial rise, the market had second thoughts about Costain's (COST) proposed takeover of May Gurney (MAYG:AIM), sending the predator down 5.9% to 285p. The deal is structured as a merger, but Costain is actually paying a premium to gobble up May Gurney, as we discuss in detail here.

Life insurer Prudential (PRU) fell 3.6% to £10.58 after being fined £30 million by the Financial Services Authority (FSA) over failing to inform the body of its proposed £23 billion bid to buy Asian insurer AIG in 2010.

In a first half pre-close statement, the UK's biggest tile specialist announced a 2.2% fall in Q2 like-for-like sales, versus growth of 1.6% in the first quarter.
