bhp and rio tough to call

Seems to be no stopping these two. Are we looking at a 12.00 bhp.

Have had a small short on rio the last week but its
crossroad time again, again. These stocks keep defying gravity. 5 days of falls recovered in 2 hours. Feel like i've been put though a washing mashine, tossed left to right.
What do you more experienced think of todays moves.

I was expecting a degree of volitility so my position is very small but i'm more interested in reading it right, the money factor is insignificant.

Are we seeing the next leg up ?

Cheers.
