Will Moderna Vaccine progress effect MSB SP?, page-9

The share price goes up. The share price goes down.

Whilst it is likely we'll see a pullback in the price today, as so often happens after a big uptick, the price will continue to be driven by the expectations of a positive result for multiple MSB treatments.

It's probably a pointless exercise to analyze every price movement and try to point to a reason for that move.

As discussed on HC multiple times, vaccines are not in competition with MSB's products. MSB's far greater problem is producing enough Ryoncil to meet demand, if we get approval.
