GERN dropped very badly in premarket today because of some bad news involving Johnson & Johnson's (NYSE:JNJ) Janssen unit. I was curious to see if there was any insider trading in the days before the news was released. I found out there were two transactions, both of the director and the secretary sold a total of $7 million dollars in late August - middle September. Usually when a single insider sells shares, it can be for many various reasons - not necessarily because they expect the price to drop. But when there are more than one sellers and they both sell significant amounts, it should be a question mark for investors. Now the price is $2.40 and I don't know if they will go up or down from here. I consider they have the right to do whatever is in their best interest with their shares and if the company happens to have bad news, it's ok to sell their shares - they did the right thing and they filed their trades in the same day.
