MRNA: Buy at the Green, Sell at the Orange, since 2020. Moderna, Inc.BATS:MRNARonbrown100Buying at the 135 day MA, and sell at 3x the 135 MA, ever since 2020 would have made a good amount of money, if the share count was kept constant for each purchase and sale. I'm thinking of buying some new near the green line and selling it at the orange. Haven't decided yet. I might wait on a catalyst ... of course their mRNA flu vaccine did get approved last week.
