2021年6月30日 I just created this chart to better understand how PTN moved on the big spike recently. Seems like it didn't take much, just a Yahoo article after the positive dry eye news and then a few YouTube videos. Here are the links to the article and videos: 12/22/2020 Michael Marcus - TipRanks tipranks.com/news/article/these-2-penny-stocks-are-poised-for-a-massive-rally-say-analysts 12/22/2020 JT Wealth - YouTube youtube.com/watch?v=H1mP74IQGng&t=20s 12/25/2020 Kenan Grace - YouTube youtube.com/watch?v=wlt93RTyN4M 12/27/2020 Kenan Grace - YouTube youtube.com/watch?v=5zpn10RupY8&t=13s 1/18/2021 Market Gains - Youtube youtube.com/watch?v=ufy7AaQF0Ak&t=51s 1/22/2021 Kenan Grace - YouTube youtube.com/watch?v=LNEAXrMQTyI&t=185s 3/25/2021 Kenan Grace - YouTube youtube.com/watch?v=B7YZDIALwF8&t=153s Potential Upcoming Catalysts Eye Preclinical - Next Anterior Indication Vyleesi - Korea PK Vyleesi - China PK PL9643 - PH2/3 Initiate Diabetic Retinopathy - File IND PL8177 IBD - PH2 Initiate Vyleesi - Multiple ROW deals Vyleesi - NA deal I would watch for the recent dry eye news or one of the above catalysts to result in another spike after new articles and videos are published.
