(ShareCast News) - London stocks are set to open lower on Monday as investors look for fresh catalysts at the start of a four-day week.The FTSE 100 is seen starting 28 points lower than Friday's close at 6,162."The run up to the Easter Bank Holiday weekend is likely to be a quieter one both in terms of trading volumes and major economic events, especially when compared to the 10 days or so that preceded it. That said, there are still some important pieces of economic data that is due out, with a particular focus this week on the UK," said Craig Erlam, senior market analyst at Oanda."This week's CPI inflation and retail sales figures are therefore going to be followed very closely for signs that the economy is stalling and more assistance is needed from the central bank, a possibility that we're already hearing murmurings of, despite the rhetoric remaining that the next move is more likely higher than lower for rates."Investors will also look to the US towards the back end of the week, with GDP and durable goods data due for release.
