Hehe, it really is true. Thatās what competition does, it drives down fees.
As far as I know, no downsides. As I mentioned itās very liquid (low spread) and itās also big in AUM (3+ billion dollars) so no chance of closing.
Iād go with SPXL or SPXP, theyāre both uber-cheap at 0.03% and 0.05% respectively. In theory, the latter should marginally outperform because itās swap based but some prefer full replication, myself included, even if itās a bit of a misnomer due to existing lending/counterparty risks.
I donāt know why T212 doesnāt show bid/ask spread, but for sure they are not profiting from it as itās illegal to add to the spread when trading stocks or ETFs (they can and do add to CFDs though).
