Trading statements are expected this week from glassmaker Pilkington, retailers HMV and Boots, the London Stock Exchange, United Utilities and National Grid Transco.

Glassmaker Pilkington will make a trading statement tomorrow. The company recently announced plans to set up a fully owned subsidiary in India. Meanwhile Morgan Stanley analysts last week downgraded Pilkington shares from "equal weight" to "underweight".

Wednesday will see a trading statement from music retailer HMV. In recent weeks the group, which already owns Waterstone's, has been linked with a takeover bid for Ottaker's. Any bid would likely draw attention from the Office of Fair Trading (OFT) and has already been criticised by authors.

Boots will update the stock market on its performance on Thursday. The high street retailer was earlier this month linked with a bid from Bayer. The German pharmaceuticals giant was said to be interested in Boots' healthcare arm.

The London Stock Exchange (LSE), another subject of intense takeover speculation, also makes a trading statement on Thursday. The LSE has been linked with a bid from the German stock exchange, Deutsche Bourse.

United Utilities rounds up a busy day for trading statements, with its latest announcement. The company has recently been having problems selling its telecoms subsidiary Your Communication.

Finally, on Friday, there will be a trading statement from National Grid Transco. Last month the company was hit by a £15 million fine for flouting safety rules after four people died in a gas explosion.
