$Moderna, Inc.(MRNA)$ For those who buy low congrats, for those who have not buy, please don't chase.

The higher is goes the greater the seller pressure when it seller come. Don't be the last bag holder. There always demand and supply. Set a stop loss if things goes south. 

Not a call to buy or sell. Market are forward pricing, guage for yourself if the vaccine could still sell to sustain current price with current PE.
