The one exception was the 2014 list, which was fractionally ahead as gains by engineer Ricardo and recently-floated TSB cancelled out another dire performance by Marks & Spencer. Most of the M&S setback was of its own making as investors dumped the shares following its latest dismal trading update, although the British Retail Consortium added to the misery with mid-week news of falling prices throughout the UK's high streets.
We will join the sellers if the price slips a few more pence to our published stop/loss target.
Other shares suffered in a global stock market retreat sparked by fears of higher US interest rates and a slowdown in Chinese growth, while news of a downturn in UK factory production during May added to the unease.
The 2013 portfolio was the biggest casualty, down 2.1% as Lloyds Banking Group and Perth-based Stagecoach suffered an additional hit from Labour Party plans to boost competition in the transport and banking sector. Jewellery giant Signet was caught up in a general markdown of retailing shares.
The 2012 selections gave up most of the gains seen the previous week, with a 1.4% slip for Greene King putting it in danger of triggering a "sell" signal despite news of stronger profits.
The overall market trend meant our decision to add packaging group DS Smith and cash-and-carry specialist Booker to the 2011 list backfired, both ending their first week with hefty losses.
We are still convinced their shares are ripe for a recovery, but their performance dragged down the overall portfolio 1.5%.
