There are many people believing that if something is 50% cheaper (half price) then it is a good opportunity. But it can go another 50% lower, then another 50% ... there is no bottom ... there are only decimal places. While doing my review today ... i looked at the list of insiders transactions. Yes ... MRNA was hugely successful on the way up with 2600% amazing performance. But since the top we are already down quite a lot (ca 60%). And you also see that insiders (both the President and CEO) keep selling .... in total ca 100m. Highest price was $350 ... and they keep selling with latest transaction recorded on Jan 13th .... Ask yourself ... if this was such a great opportunity to buy ... would they be selling??? :)
