Bill O'Reilly from FOX news' O'Reilly Factor show is calling for a boycott of French products. He doesn't have it in his list here:

but he specifically mentioned dumping the stock in his show yesterday which is much worse. He likes to get people into action so could be a reason for the drop. It may even affect them longer term, too.
