Nothing to panic about. A lot of profit taking, that's all by small holders over 2.5 million as per the chart to the right.
IMHO, I am more than confident that Orocobre will break through the $5.00 resistance in the next few trading days and push close to $5.50 be the end of the fiscal year.
Again IMHO, once clear of the $5.00 resistance level, it should be clear weather to $6.00
