I invested to Moderna believing that it will bring covid-19 vaccine. However, it seems the stock price is going through a wild ride. It surged 10% from 29.34 and has fallen to 26.30. Was there any incidents while delivering the vaccine? or is it because more people want their stock to be sold at lower price?
You are making assumptions not based upon reality. If you list all your assumptions I will explain what is not true.
You can’t expect stability in this market. While pharma stocks are the wildest of them all. Moderna isn’t doing that much more than all companies involved with vaccines. They all announced vaccines while explaining it will take more than a year to make it available. So you cannot just bet on one specific vaccine to be approved and widely used first. What a bizarre statement.
You've grossly oversimplified how the markets work and that's why you're confused. There's some 5-6 announcements of a vaccine, none are approved nor tested -- how do you know which one will make it?
In addition there are companies working on vaccines who for competitive reasons etc. do not say anything.
