There’s been a lot of interesting goings-on in the geek industry the past two weeks but nothing big enough to write an entire column about, so here’s a roundup of some interesting nuggets.

Strange goings-on at Wizard World. If you’re looking for a way to make a financial bet on the convention industry boom, Wizard World is about the only publicly-traded option. But if you go that route, pack a seatbelt. The over-the-counter penny stock has been subject to a lot of turbulence in recent months. Monday morning, WZD plunged from $0.45 per share to $0.30 – a huge percentage decrease – on trading volume six times greater than average. It eventually closed at $0.37, a nearly 20% single-day drop.

The company has not reported quarterly earnings since November 2015. There have been only a few disclosures from the company in recent months:

That’s an interesting sequence of announcements for a company that is about to stage its premier event, Wizard World Philadelphia, in early June with a celebrity lineup that industry insiders speculate could be costing well over a million dollars in guaranteed appearance fees. And something just caused the stock to plummet again Monday morning. Wizard World did not immediately return requests for comment.

What’s going on with Batman v. Superman box office numbers? Speaking of financial roller-coasters, the announcements around the financial performance of WB’s box office tentpole Batman v Superman: Dawn of Justice have been a mixed bag to say the least.

First we heard that it destroyed a series of Friday, Saturday and Sunday box office records on its way to a gigantic $424M worldwide opening weekend. At the time, it seemed surely on track for an easy billion, maybe more.

Then it came out that the film suffered one of the largest day-to-day drops between Friday and Sunday of its opening weekend, and that’s not all. My colleague at Forbes Scott Mendelson observes that BVS is now the second member of the very exclusive $100M Losers Club, having dropped $121M from its first to second weekend. The only other member of that club? Harry Potter and the Deathly Hallows Part 2, which dipped 72% in week-to-week domestic box office, for a disparity of more than $122M (for more, see “Number One with a ‘Sinker’”).

On one hand, it’s a sign of strength that a movie could shave $121M off its domestic box office week-to-week and still win the second weekend with a $52M take. On the other hand… wow that’s a big dropoff, to go along with notoriously terrible reviews (29% on Rotten Tomatoes, 44% on Metacritic).

Despite this gap and a trendline that now points toward a gross of under $1B worldwide, Tim Beyers of The Full Bleed estimates the film will still be enormously profitable for Warner Brothers when you account for all the tax advantages, product placement, licensing and partnership marketing. Beyers says it would take a considerably stronger performance for BVS to match the profitability of Deadpool, however.

CBR Acquired by Valnet. Finally, some news came across this morning that comic news supersite Comic Book Resources (CBR) has been acquired by the Canadian firm Valnet, publishers of a site called ScreenRant.com (see “Comic Book Resources Acquired”). CBR’s founder and executive producer Jonah Weiland announced the news in an email to CBR staff and contributors on Monday morning, and also indicated that he will be leaving CBR following the transition to new ownership.

Considering the number of comics/geek culture news sites that have shut down, contracted, changed leadership or changed focus over the past 12-18 months, it’s interesting that one of the largest and best known was seen as worth acquiring. Bleeding Cool’s Rich Johnston, who got his start at CBR, estimates the deal could be a “seven or eight figure sum.”
