The BlackRock fund is still down a but I have held it longer than the physical gold ETFS and so it would be misleading to see it as a less successful investment.
Basically I sold all of my PHAU shares back in December 2011 (at a £250 loss) and couldn't make up my mind whether to buy in January and didn't own any again until March when I paid £1066 for 10 shares and then again on April 4 2012 - 10 shares for £1009 and then another 10 shares for £978 on May 9 2012. All together my ETF holding is now up £146 so I haven't regained the original loss.
What I might try and work out is whether I would have lost less if I had simply held on and bought more.
