The stock market's overreaction this week was mainly due to the fact that most countries are preparing to open and are opening up. The sudden transformation of the epidemic means that the open economy may reverse, causing market panic. When the US, Britain, and Singapore announced entry bans on some African countries, it also highlighted concerns about the epidemic. Personally, I don't think it's over yet. Every panic doesn't bring about an immediate correction; instead, it continues to explore the bottom until the panic is over. When will the panic end? Pfizer says it will take 2 weeks to know how effective the vaccine is against the virus. Why not wait? Or is it down to the bottom now?
