"The momentum in equity indices is clearly positive, but with the major European markets perched at their recent highs there has been a drop-off in volume as fear of paying the top starts to come into play," he said.Nevertheless, traders were shrugging off the news that UK retail sales grew at the second-slowest rate since 1998 last month.
