Yes a few years, like many others I was attracted to the blue sky prospect of E Commerce in China and 99 Wuchian was a share of much interest which I got involved. I could have made money there but I held on because I believed in the e commerce story so eventually black became red and got redder and I had to pull the plug because it didnt look right, and fortunately when I recognise that I was wrong (on the stock) I was quick to act to sell completely, as if I had not, it would have been a disaster for me. It was the right sector but the wrong stock and AFR today documented the plight of shareholders who held on to it.

Since then I vowed not to touch any stock with Chinese interest for lack of transparency and sadly integrity. And likewise I am also wary of Israeli owned stocks (eg SAS) who are coming in with highly valued IPO.
