Our share tips pushed to yet further record valuations last week, with all four portfolios making progress after suffering earlier from stock-market jitters.

Admittedly gains were more modest than in past weeks after the FTSE 100 share index plunged 100 points on Monday, but the 2010 portfolio still managed a 1.3% increase and the others were not far behind.

Many share prices are now in danger of profit-taking after recent rises but the overall performance encouraged us to dip into reserves with another notional purchase at our review on Wednesday.

We believe oil and gas group BG has now established a firm trading range after disappointments over production levels, and should be ripe for recovery as investors concentrate on the potential of its major finds in Brazil and Australia. We have set our usual stop/loss level, 10% below the current share price.

While trading conditions were a little tougher last week, a number of selections pushed to fresh peaks and we have raised stop/loss levels accordingly.

This list includes housing-based companies Galliford Try and Grainger, Greenock's British Polythene Industries, Irn-Bru manufacturer AG Barr and catering giant Compass.

Recent favourites Standard Life and Centrica were both marked down after recent rises and Stagecoach was our only loss-making selection. We still believe the Scottish transport giant looks undervalued at these levels.
