I disagree.
The share price fell right when it was announced that the offering price would be 7.5 cents. Arbitrage.
Second, going from 70 to 50 cents on JDZ drilling news is hardly a realization by the market that there was only biogas found. If the market knew that then the price would have dropped far, far, further than that.
A 70 to 50 cent move is nothing more than investors saying to themselves, "this is good enough for me". Some said that, others didn't.
Taking chips off the table is something that stock investors do all of the time. When one stock within your portfolio ends up becoming 80% of your portfolio because it appreciated so much, many investors will re-balance their portfolio by selling some shares.
I challenge you to find ANY company which rockets several 100% and DOES NOT pull back at LEAST 30%.
