Yes, not substantial. It was a long August call. And I wanted to avoid the time value loss as I don't expect a very soon rise now. I agree that BHP is worth a strategic investment and will revert to this idea later.
Thank you for joining this idea. I even thought about Biliton as a strategic investment. I had not realized the bearish divergence of the MACD however. But the bottom of the monthly chanel as you show it supports the idea well.
Do you have an idea of Turquoise Hill (THQ)?
the arrow i shown is kind of pre-mature bullish hidden divergence but if it happen then it is really bullish as you can see that price isnt dropping anymore http://www.babypips.com/school/high-school/trading-divergences/hidden-divergence.html
