And to also quote the Motley Fool...

Northern Star Resources Ltd (ASX: NST) is another gold miner suffering heavy falls today. Its shares are down 9.7% to $2.98. The share price falls have likely also been caused by the unfavourable movements in the price of gold and the Australian dollar. The losses have perhaps been exacerbated by the announcement of three analyst downgrades this morning: Deutsche Bank and Canaccord Genuity both downgraded to Sell from Hold, while Macquarie downgraded it from Outperform to Neutral.

For me, I think it is still a sell.  It over ran, people will be profit taking, possibly over shooting before bouncing back again, especially if AUD shows strength and USD Gold controlled.   IMO only of course.0
