Afrosia - you are 100% correct in your analysis. The fund share price today is irrelevant.
VinoDiony - not sure what your tracker portfolio is tracking (i.e. its obviously not the FTSE100), but I would say that the Bolton fund has held up very well since its launch considering the fall in the markets as a whole.
I would rather have a bit of my portfolio in places like China where people get worried if growth falls to 8.5% as opposed to the 10%+ of the last decade than have all my eggs in Western markets which are likely to tread water for several years to come.
