Gilead's market cap increased by ~15BB after Stat News released a story about a video showing Chicago area doctors and nurses casually discussing redeliver and saying that they thought it worked. That was after the close and after market trading. Someone thought that a rumor that the drug was effective was worth $15BB.
For CYDY, $15BB translates to ~$22 / share (you have to assume the fully diluted share count is close to 700MM because their warrants are so deep in the money).
Another way to approach it is from revenue assumptions. CYDY will have 1.5MM vials of drug delivered in 2020. That's 750K doses and at $1200/dose, that's $900MM in revenue before royalties or distribution. In 2021, they've ordered 5MM vials which is worth $3BB in revenue. Small pharma often trades at 10x revenue.
