So I noticed the article linked beneath and was questioning if all of the platforms charged a further charge if you happen to purchased a fund not belonging to that particular firm on their platform. I.e. shopping for one thing like VOO on Schwab or Constancy or shopping for SCHD on Constancy or Vanguard would imply you would need to pay a further charge since you were not shopping for them on their particular platform.
So the query is that if I wished to purchase funds like that, am I higher off simply opening a brokerage account on that platform to keep away from the extra charge? Or are these charges negligible?
