I'm always a bit antsy when $Moderna, Inc.(MRNA)$ reports earnings, especially when the share price is increasing in the run-up to the release. But this time, the company has a lot of momentum behind it and other than letting go of one 27 Aug 350 that returned me a 300% gain, I'm holding onto the rest of my position.I've seen a few posts comparing $Tesla Motors(TSLA)$ and $Moderna, Inc.(MRNA)$ , but one big difference between the two is that a Tesla is a luxury purchase and the Moderna jab is a basic necessity.
