Dow Jones short! Overbought and euphoria.

First of all. I don't think, we'll see any vaccine next two months, covid is a seasonal illness and december is hard (you can see flu season statistics, most of the times respiratory diseases start to became really hard in december), and because of appearance of new strains we will have to make new vaccines every year.
Second of all. Moderna. A lot of insider sells. I'm really scared of them -.-
And last. It's overbought. We can see 30150 today, maybe more, but then it will fall down, because it's abnormal behavior.
Good Luck!
