If you believed in the EKA story then it does seem foolish to think about selling the stock equivalent of CER.
Just think about it. EKA was always going to need financing to do anything with CHELY so dilution was certainly on the cards. The Moly sales have been already committed to repaying a loan, at least initially, so that usable cash to run the co was in short supply. Didn't you think this a problem? yet you still invested.
What has happened solves a lot of the shortfall of EKA. CER has cash and will be in a much stronger position to bring Chely to production and hang on in there until the Moly sales are bringing in revenue.
From my point of view the T/O is the best thing that could have happened to EKA. I certainly didn't like the SP of either co at the time but to me that is not the point.I had no intentions of selling until the value of the resources has been recognised by the market and then I will invest in another growth story and no doubt go through it all again before (hopefully) I make money on that company too. The frayed nerves and noise in between is not worth paying too much attention to. By all means keep stop losses but if you decide to hold until the big picture is played out you shouldn't beat yourself up about it.
Just about every stock I have ever owned has dipped (or dived) below the price at which I bought it. In most cases if the story is good the SP recovers. (if the stock was CMR ultimately the Spanish story wasn't good and I lost money but this was an exception)
What is important is the SP at the time you buy and at the time you sell.
If however you have lost faith in the management to deliver then this could well be a reason to sell but think of this The new management were clever enough to get EKA cheaply you have to give them credit for that. Maybe they are clever enough to make you some money too!!
Oh well in the end it is your decision but try not to make emotional decisions based on feeling angry at the take over arrangements. DYOR etc and think about what you find out.
All the best
