@Transversal,
You're probably right; all other things being equal, I should be buying in now, with the price 40% lower.
Especially given that since I sold, it turns out that the Revenue milestones I had set still appears to be intact, after all. Meaning that my concerns were unfounded.
Trouble is, the passage of just three months has left all other things quite different to what they were when I sold. The ructions in markets in recent weeks have left me somewhat overwhelmed with emerging choices of alternative investment opportunities other than OMN.
So, yes, I'm inclined to do as you say, namely buy back in, but every day I wake up there seems to be something equally, or more, appealing to buy. A bout of mild choice anxiety prevails.
So, a bit like the bunny stuck in the glare of the headlamps, I'm simply doing almost nothing in terms of buying or selling shares.
