I agree with you.
Probably T212 could have some automated investing strategies with ETFs, using or not, the Pies, like a robo-advising service for investors that want passive investment or don’t have time, formation or the will do the proper due diligence to invest. For example:
- Retirement Strategy
- Dividend Strategy
- Growth Strategy
- Low Volatility Strategy
The investor choose the currency and the Strategy, with or without answering some questions first about his/her investor profile.
(T212 could take some of existing ETFs fees and/or could have a fee for the robo-advising service.)
Returning to OP, just to put in perspective, Morningstar (Europe) has 11015 ETFs, it includes all versions (stocks exchanges, currencies, distributing/accumulating, with/without currency hedge, long/short, leverage/non-levereage) and the several legal structures (ETFs/ETCs/ETNs).
It could take some time to add all that and make fractional. Some will not added due to low volume or other considerations. In the end, T212 is dependent of IBKR offer.
