It's meant to be alpha-bet, where alpha is investment return above benchmark.
Ahh that makes sense, like seeking alpha. I was thinking it was due to indexing things from A to Z.
There is definitely double entendre going on, which is why they picked that name. At the surface it means one thing, but it has a second more relevant meaning hidden in there. They make bets which make great returns on investments, and these bets cover everything from A to Z.
