No, it is not. you need a "material event" (negative in this case) to send the stock falling like this. A positive material event would send it shooting up. Is that really so hard to understand??
In a sense, yes. Some events—such as the start of the NEO phase-1 trial—have been pushed out to a significant degree (#msg-134670005). Other events, such as the SITC presentation of the AXAL/Durvalumab data, have been nixed entirely (#msg-135694047).
