I wasn't expecting a bounce. For companies that I watch, around SDCC, it's more about possible new projects announcements/deals. No new deals/projects, no bounce. SDCC attracks good worldwide media attention, so it's a good place for small company to announce stuff.
Also, if there is no history of good money making deals being announced at SDCC, there isn't much chance people will drive a stock's share price up going into SDCC.
REDG's panel is on Sunday, maybe some mega-deal announcement will be mentioned there. At the very least, they should mention the "Waywards Sons" new comic book.
