I suspect its more fundamental than that. Big run up from the 30's to near 60c over 3-4 month. lots of folk in the green probably taking some profit off the table as the latest run lost some momentum. It seems counter-intuitive but this is a predictable and healthy pull back. heading into a pretty risky phase with commissioning often throwing up lots of quirks....
i started buying small parcels at this 40-42c range as it looks like where it should consolidate and await renued enthusiam as it its already tested this support once. It may go lower, but shouldn't be by too much or for too long. if they can deliver the numbers that suggest and avoid delays or CRs (which that suggest they won't need), then the next 24 months should prove to dramatically firm up the SP based on what ever metric EV/EBIDTA, EPS, PE to sector multiple.... Just got to see the retracements as opportunities to load up or wait out.
