Three of the four portfolios stretched to new 2012 peak valuations and the 2010 and 2011 selections passed milestones with gains of more than 80% and 50% respectively.
The 2012 portfolio also hit a fresh marker with a further 1.7% rise taking total profits past the £2000 mark for the first time.
Only the longstanding 2009 portfolio disappointed when we conducted our review of progress on Wednesday morning with its overall value virtually unchanged as a slippage in building supplier Travis Perkins cancelled out gains in Marks & Spencer and Diageo.
We accept it will now take a Christmas miracle for the portfolio to meet its target of 100% appreciation by the time it is wound up at the end of the year although it has easily outstripped a 34.6% rise in the FTSE 100 share index over its four-year life span.
The overall performance was again boosted by solid investment support for Standard Life and Aberdeen Asset Management, which have enjoyed a stock market re-rating in recent months.
We have no reason to believe they will not continue to rise but we have set fresh stop/loss levels some 10% below current prices to ensure we can lock in the bulk of the gains.
AG Barr also received a new stop/loss target as its price responded to an encouraging trading update and the prospects for rationalisation gains after its tie-up with Britvic.
Moodiesburn sausage-skin group Devro came within a whisker of triggering its own sell signal early on before staging a useful recovery to end the week marginally ahead.
