Trade volume has been extraordinarily high over past two days.
Is it:
* People jumping ship, and not valuing the benefit of the actual and probable franking credits?
* People thinking their main money is made here, and the the time to benefit can be put to better use elsewhere?
Or is it:
* Buyers happy to take shares from sellers at current value on the possibility or even expectation of passing them on to another bidder ?

The price hit $2.47 a few times today - small volumes, but interesting. We may yet see a spike in the price on expectations of obtaining a higher price.
