Strong volume of million and half by noon. Combination perhaps of profit taking by traders and some who missed yesterdays action. Also some buyers perhaps expecting news first thing this morning and sold when not received.
Always hard judging these kind of movements when we retail holders can't see much reason for the fast scramble for shares. Even more so when it seemed to involve a lot of 'ROF' players in addition to Noront.
A lot of good guesses on this forum and no doubt several will turn out to be correct. Meanwhile lets enjoy the nice increase and watch how the afternoon unfolds.
