That's clearly show how dangerous to hold BBOZ for long term.
you can simply calculate.
ex. share price 10. I will use times 2 only.
day 1. up 10% 10*1.1 = 11
day 2. down 10% 11*0.9 = 9.9
day 3. up 10% 9.9*1.1 = 10.89
day 4. down 10% 10.89*0.9 = 9.801 (No changes on index but you will lose at least 2% + management fee)

If you intend to trade geared product, please be mindful that this is not a long term product.
Just buy only when you need it for short term.
