Seems pretty unlikely that this fake tweet affected the company's stock. It's odd this reporting has survived.

Other similar companies that are not in the Insulin business in any way moved down by about the same amount at the same time. Eli Lilly's stock has mostly gone back up. Also the timing is off, the stock moved after open the following day, after other news was announced and not in line with the timing of the tweet's creation or growth in impressions.
