Here is a "more reasonable explanation" for your tiresome paranoia:
Pharming had a precipitous drop in its share price at the same time as GTC. Why? The EMEA announced a negative opinion on Pharming's MAA for Rhucin. Pharming announced it will appeal.
Do you suppose there was a knee-jerk reaction on the part of some GTC shareholder(s)? Do you suppose the fact the negative opinion was known, or at least suspected, before it was announced this morning accounted for some of the volatility in the GTC share price the past few days?
