I think the markets will go up this week strongly as they have been trying, but the worries over Oil have held them back, now that OPEC is increasing output. The DOW should have a good week.
BHP appears to have come of support in the UK now and the Australian Chart looks good to.
I think BHP will get to 4.80 in the UK this week, which is 12.30 Aus. Add say 2% premium (Light compared to 7% generally) and we have $12.54.
Un-fortunately People in May warrants will loose mostly but those in Jun Calls for instance will be big winners.
I personally will call BHP around 13.50 Next month. Only my call though.
