It's true that it is only marginal profitability, but surely the fact that it is no longer a drag on the business should be worth something (if they can keep it that way). The last two months, the sportsbook was -87 and -35; this month +2.4. The trajectory of sports definitely seems to be in the right direction but the BTC and $ denominated share price went down (a bit and a lot respectively).
The only way I could see to justify this is if a) CBTC was massively overpriced for the last couple of months (or is very illiquid now), or b) you don't believe the sportsbook trajectory and believe instead that there is huge overhang risk from sports and we just got lucky this month. Does that make sense?
