They (market makers) must know that people (retail) are using BBOZ instead of CFDs to go short, and want their money as well, can't let anyone enjoy the ride down and scoop up discounts later on. I can't recall any time that BBOZ has been positive at the same time the ASX200 has.

Perhaps there's just so many people wanting to get into it that Beta isn't able to sell down quick enough to match the supply side (please correct me if I'm wrong with how this product works). I know it's meant to inversely reflect the futures, but people are using it as an inverse index ETF because there's no other options. I originally bought it without realising it tracked futures.
