I do not expect any significant price action in shares of Hepalink before top line is officially released, however it is possible that in case of good news, info is leaked to China, and that Hepalink gets bid up a bit.
Assuming positive top line is worth a billion or two in market cap (%RRR still unknown) then Hepalink’s market cap should move commensurate with their stake in RVX. Their market cap is currently $5B (CAD) and they own almost half of RVX so it should be significant to their stock price if top line is positive. If negative I don’t think it’ll be as significant.
So what to watch for Sunday night is a big move in the positive direction in Hepalink shares. That will mean something. Anything else reveals nothing imo because maybe no info has leaked.
